i think it has been said, but: what focal length to use for what purpose is mostly bs. who said you can't shoot landscapes with a short tele? or a long tele. you can do whatever you want, experiment, and don't worry about rules so much. (i'm sorry, i no longer have pictures online to show examples)

wide angle: 18mm on apsc is not at the limit, it's "right in the middle", it's a respectable wide angle (like 28mm on 35mm film). a 24mm would be a "mild wide" on aps-c. a 16mm would be in the realm of ultra-wide already. Beware of wide angle lenses, you need to learn how to use them effectively, otherwise the pictures will not be making any sense. i suggest to start with this idea: a wide angle requires a foreground, subject, and background. the foreground is almost always not optional ;)

for instance, two rather boring pictures, taken in the same area (grossglockner hochalpenstrasse -- hey, don't tell me, tell the austrians):

http://www.alpy.net/grossglockner/obr/glo_206.jpg

https://www.pentaxforums.com/gallery/images/3491/1_K20A9851-watermark.jpg

they both seem to be shot with a wide angle (i guarantee for the second, as i shot it), but in the first you can't quite tell if it's a wide or not, and it has that "meh" look about it. Now mine is not something to make you sit up either, but you can see the foreground gives it some "depth", this is one of the "magic" things about wideangles. Until i figured this out, i hated wideangles with a passion.

the pentax kit lenses are generally very decent, so you will find it hard to compare the iq to old primes, but it is, almost always, better for the primes. add to that the elegance, size and "pleasure to use" of the primes, and you'll see why many people are addicted. however, this does not mean they are for you, you might be fine with the zooms and take great pictures with them.

landscape/dynamic range: i happen to hate the hdr look, what i do (used to*) is to use a little piece of software called "enfuse", it is part of hugin, and it is great (it manages to do exposure blending in a "reasonable" manner, to my eye, without the tone-mapping insanity). hugin is worth having a look at in any case (probably the best software for panorama around these days, and open source)

* used to because, since i switched from k20d to k-5, i ended up taking "one shot" instead, the dynamic range improvement was so dramatic for my needs that i found myself leaving the tripod at home at times, and trying higher iso handheld (yeah, i know, blasphemy, i was having fun though); having said that, in extreme situations, using something like enfuse to bring the dynamic range of the raw into a jpeg might still be worth it.

bmx bike: interesting, i must consider a trip to new york one of these days. everywhere else in the world we call that a wheelbarrow :P

right. my post was already too long as it was. my point was "making money out of a hobby almost never works", in the sense that it will not longer be the same thing. of course it can work out for some people, for some it can work out very well even, but it's not the same anymore (and that can also mean it's "more" and "better" - different), was just trying to warn of that, not to say "it sucks, don't do it", sorry if it sounded like that. I guess jatrax' story pretty much sums it up (or gives a good example at least)

seems like a lot of sane people on pentaxforums ;). your gear is fine, your pictures (technique) decent.

disclaimer: i am _not_ a professional photographer myself.

if you want better, especially commercially, i'd say:

- focus on a specific area (like "baby photography" or "portraits" or such)
- learn to use your gear (you have excellent gear, nothing of what you have is bad, the k10d is an excellent camera, manual focus lenses can be hard to use but not that hard to make them useless, especially in "studio"); learn how to use your lights, play a lot with lighting, that's the most important thing, technique wise
- close your aperture a bit more in the studio, to get some dof, and be freed from the worry of missing focus if the model breathes ;)
(consider even a cheap focusing screen for the k10d, if you don't have one, to help with focusing those manual lenses)
- play with the lights more, (did i mention play with the lights?), maybe add a second yungnuo flash (they are perfect for studio work -- i prefer mine to the dedicated pentax flash -- and cheap, very good choice there); radio triggers as mentioned are nice
- don't worry about the body, k10 is fine as long as it works. if you have the budget, anything current is fine (k500 included). if budget is tight, keep shooting the k10d.
- you have a decent lens lineup, keep using it, learn it's strengths and weaknesses. you will know exactly what you need if you will want another lens, only then, it's time to shop for a new lens.
- if you want to make money, remember it's hard work, extremely competitive, and it has to do a lot more with how you market yourself/how well you do business/how well you make and keep connections ("industry socializing"), than with how good your work is (not that quality of work doesn't matter, it's just it is not enough)
- before you quit your day job, shop around for the kind of "pro" services you want to offer, in your area, see what are the going rates, make an assessment (a very honest one!) of what that would mean if you were to work at those rates (how much cash in, the first two months? does it cover your expenses? how much will you work for that cash? can you really expect that much work coming your way so early on? (recalculate) etc)

there's some pros who have recently been very open about talking about the photo industry, and what it means to make money like that (Zack Arias is one of the popular ones, you will find some of his videos easily; keep in mind though that applies to USA, i have a hunch that's not where you are, so beware)

word of warning: all pro's i've ever talked to or heard speaking about this, will say that "yeah, photography is fun. if you're an amateur"; doing something professionally (for money, against a deadline, with set expectations, needing to deliver, etc), is not the same as "just doing it how and when you feel like it"; watch this carefully:
















You Tube




this one is quite a bit longer, personally i find it insightful:

good luck!

well, yes, in calling me out that i'm doing this in the wrong place, so i guess you're safe :P



mhh, note really. in fact slightly faster works fine when panning, and even much faster works fine (though the "farther from sync you go" the more problematic it gets, panning aside), the only problem is that it will not fix your panning technique magically, basically what happens is if you're able to pan "well enough" for the sync speed, you'll be good, if not, increasing the shutter speed will prove frustratingly ineffective (not useless, iirc, but not even close in effect to what you'd expect); the picture will not look the same (many other things will look different), but neither will the faster shutter "fix what you want fixed", at least that was my experience (not scientific testing though, and other things come into play too, like focus, etc, so obligatory grain of salt etc)

i didn't mean to speak about panning exclusively anyway, but i admit i almost never shoot fast moving subjects from a tripod with high shutter speeds, so some sort of tracking is included in almost any action shooting i personally have experience with.

do you think the discussion is interesting enough still to move to a separate thread? i'm still curious what controlled testing will show, but i'm definitely not about to continue this here. beginner thread or not, this is clearly offtopic for this thread.

i think old members and new ones alike need to make sure before making definitive statements. i already explained it's a bit more complicated than your simplified version above, even from the first post. you're trying to disprove something that was never stated, and with all due respect you don't have the data to go after it (and neither have i, as i already stated). read my last statement and think again

i would gladly do some testing, just for fun, (and i'm sure i'll find the results interesting even for myself), but i just didn't have the time. if you think no testing is needed, and that your "1/4000 is 1/4000 and the fact it's a rolling shutter makes no difference" is all there is to it, well..

happy shooting

the term "rolling shutter" has been made famous by the emergence of consumer video devices, but in general the term rolling shutter applies to all such shutters (where portions of the frame are exposed at different times, as opposed to a global shutter). anyway, the topic is a bit tricky and apparently people find their rolling 1/4000 very dear to their hearts, so let's let it rest or move it to another thread if somebody is still interested. in short, a rolling shutter works fine for "mostly static" subjects, or for freezing "local motion" within the frame (think of turning wheels on a fast moving car), it's not so good at freezing motion of the subject across the frame. Let's leave it at that.

"So you can give all kinds of great technical explanations, but it won't work because you're leaving something critical out of your theory."

i'll be the first to accept this, but it would be interesting to know what it is i'm leaving out ;)

the theory here is indeed a bit non-intuitive, and it might not apply to many situations (like movement which is "composed", as i noted, not predominantly in one direction -- like the hokey examples). most of my experience with action shooting is rally (which is very different form hokey or runners etc), i agree without a test the "theory" is questionable.

to be fair, the discussion should have been started separately, not in a beignner thread, you've got a point there, i can see how it can only be confusing to a beginner. my bad there.

note: i never said "don't use anything above 1/180" i just said "don't expect anything above 1/180 to do miracles", that's all.

i'd say let's park this, or maybe move it to a different thread, so as not to hijak our new members thread (again, my bad there, apologies to the original poster)

who will laugh your behind off at you, and what's true and what is not, are two separate matters (see "appeal to authorithy"); have you tried asking though? it's very hard to grasp what a "rolling shutter" will do at first glance, and it's not as simple as i tried to explain it, because i don't want to write novels here, but you can try a test with a fast moving subject across your frame, with the camera on a tripod (should be moving on the long side of the frame, and fast enough that sync speed won't freeze it), and see what you get with different shutter speeds. The rolling shutter might help some, but it won't freeze the overal motion (like a global shutter or central shutter will do), and in my experience the results show that. ymmv etc.

i owned the tamron 70-300 when i was much younger :P , it did great on a nikon d50. i only had one major problem with it: chromatic aberrations, particularly at the long end, were horrendeous (really spoiled the fun when shooting concerts, or rally -- if sunny). CA can be corrected in post processing though, or so i heard.

when i ditched the nikon for my first pentax (k100d, yeah, i'm old :P ), i got the 50-200; my first impression was: 1. same image quality, smaller, nicer build 2. the almost inexistent CA (by comparison) can make up for many shortcomings 3. de missing 50-70mm range was more of a pain than having 200-300mm was a blessing (note: i still have the 50-200, and i still think it's a perfectly decent lens for what it is)

don't disregard the possibility of a good old manual prime if you're on a budget. you'll need more care and "think more shoot less", but personally i enjoy the results from such good lenses, and the process of shooting them, enough that i ended up shooting rally (when i was still doing that) only with manual focus. You can easily get a 200/f4 for under 100usd, it will only be challenged, as far as optics go, by a modern 70-200/2.8, but it will walk all over any consumer zoom.

if you'll get either of these consumer zooms, remember you'll not be shooting any birds (ahem, any-thing) unless it's sunny and bright (well, the awesome sensor in that k500 will help a lot though, so maybe partly cloudy might work too), and you shouldn't expect "premium image quality". and remember, with the camera you have, there's nothing preventing premium image quality to be put out, except the lens (i'm just sayin'...)

btw: the k500 is the greatest entry level dslr ever marketed, okay, so it has no weather sealing, but that's the only thing it's missing (i'll keep quiet about the focus indicators). it's a great camera, don't complain ;) (sensor, build, viewfinder, ergonomics -- with dual controls!, almost a danger to the k-5 :) )

for macro of that sort, prepare to spend some time and effort, it's not easy. a good example of a success storry is

Thomas Shahan’s Spiders in National Geographic | Flickr Blog

this guy used to use a pentax k200d (i think some time ago he said he had moved to a k-r -- not that it matters), an old manual focus lens reversed and on some extension tubes, and (most important) his own home made light box with a flash in it to light his "models".

so not necessarily expensive, but lots of work. not something you can do casually, if you want it done well. (hmm, that applies to anything worth doing, doesn't it?)

nope. you are assuming i'm assuming :), i said nothing about flash. the problem is that the shutter is only as fast as the shutter is fast, which is the sync speed (the fact sync speed is also meaningful for flash is "only a coincidence"), and while using rolling shutter to make exposure "locally smaller" (or, if you wish, locally increase the shutter speed) seems to work, the speed of the shutter on the entire frame is the same at speeds at and above the sync speed. this basically means that if your subject covers a significant portion of your frame (aka: is not a speck somewhere in the frame), using speeds above sync will not help with freezing motion: you will need to track the motion as well as if you were using the sync speed, to get something decent. it might help with some local movement on a subject which is complex-moving (like a bird feathers in some areas? neh), but this is splitting hairs. the simple rule for a beginner to remember is: "when shooting action with a "rolling shutter" (focal plane shutter), use whatever shutter speed works for you, but remember no speed is really faster than sync speed, and pan -- and plan -- accordingly"

welcome and have fun, sorry i didn't see the thread earlier. what i would have told you would be "go for the k10, if on a budget, and stop worrying". basically any camera made by pentax (and frankly all the others too) after the k10 (included) is great, the k10d is also a piece of history (a game changer). in other words, the k-r is absolutely fine, stop worrying and continue shooting, you've got great gear.

shutter speed: this is a commonly misunderstood factor i feel: for sports (subject moving across your frame), the highest useful shutter speed is really the sync speed (modern dslrs means somewhere between 1/160 and 1/250, pentax is 1/180 i think), making it faster than that will help little if at all. higher shutter speeds are useful in bright light, so you can control your aperture (use a wider aperture for nice dof effects etc). to understand why that is, you'd have to learn how a focal plane shutter works, if not technically inclined, just remember the rule above and keep it in mind (it will come in handy when you're shooting rally and bump the shutter speed to 1/4000 or such, at cost of iso and dof, and see no improvement in "motion sharpness", you will know to clam down, bring iso back down, aperture back up, and start tracking the motion carefully ;) )

edit: hmm, let me tone that down a bit: let me replace "higher than sync speed is useless" to "is problematic at best". experiment and you will see ;)

for the curious: http://en.wikipedia.org/wiki/Rolling_shutter

have fun, and stop worrying about the gearfor a year or two ;)

okay, Professor (and i say it without the slightest hint of sarcasm, btw), your logic is, as seems to be the norm, rock-solid. There's only one tiny problem: your starting assumption is wrong;

most people don't worry so much about destructive impact. The truth is most modern cameras (dslr and up, not "digicams") couldn't withstand an impact capable of _incidentally_ destroying the back lcd, and keep on going (without internal damage etc), most people don't actually expect a dslr to survive a 3 foot drop for instance (though i hear many will, surprisingly enough, survive), after all our beloved celulloid film has turned to glass. etc.

the problem is mostly perception, but not all perception:

- a hinged/articulated screen is mechanically more complex, hence more prone to mechanical failure (how many fixed panels have you seen fail to.. ahem.. stay fixed, as opposed to damaged/worn off hinges on a car door?); yes, it can be well built, i admit, but you can't help thinking that "all else being equal(...) the fixed design will be sturdier"

- a fixed (burried/built into the body) screen will not catch on things, cloathing, etc, this means it is unlikely to incurr any un-intentional shock, and it is also less likely to cause loosing grip on the whole camera and potentially causing the camera to take a flying start to the bottom of the valley. silly? paranoid? perhaps, but some people shoot in rather extreme conditions, and apart from equipment cost, the loss of a camera will basically spoil an entire trip (especially a photo trip)

- a hinged/articulated screen will have a mecahnically mobile connection to power it and feed it data. some can't help cringe at all the trouble they have seen with even semi-mobile electrical connections of any complexity.

- some people don't trust the ability of properly weather sealing an articulated screen. obviously, it won't be impossible, but it seems many manufacturers struggle to seal "monoblock" cameras (see the long range of "sort of kind of maybe sealed, in places" canon x0d). I'm even more disturbed by this than most people, because while i love pentax and am used to having proper sealing, i _know_ that most decent quality cameras these days are in fact effectively sealed to some extent (tight enough tollerances by design/manufacturing process), but when you put a hinged screen on them, you're inviting moisture not only to enter in new and previously in-accessible places inside the camera, but also invite water to "stay for tea" in "water trap" areas; of course this can be alleviated by very clever and careful design, but such design is even more expensive than proper weather sealing itself i reckon, and i am talking about non sealed cameras to begin with, that are designed to (officially) never be used in such conditions.

having said that, i agree the idea is good (i always loved the waist level finders on my medium format gear).

anyway, can they stop playing silly buggers already, and bring on the wireless remote screen (perhaps with an "eye mounted" finder system, using the excellent electronic finders in some mirorrless cameras today)? it is clearly possible, it's just a matter of wanting to do it. i see no reason not to do it, sounds like a killer third party accessory to me (especially as many cameras have hdmi outputs and such these days), and an even more killer "system gimmick" for any brand who comes with it first (because if done properly, with all needed overlays, etc, it might be not only worth getting it instead of the third party, but make the system on the whole more desireable); not to mention that, again if done properly and paired with proper remote control "bundled in", serious sports photographers would eat them up.

ahem, excuse me while i go and file a patent or two :P

please stand up and apologize. the highly scientific nature of this discussion demands the utmost precision, and you just went and screwed that up with your layman terminology, in the process making all participants to the discussion look like "common people" (how dis-tasteful). and don't you dare bring up the argument that "how much does this weigh" is an accepted english inaccuracy, and that the expected answer is always in units of mass. Nor do i expect you dare point out that, as "how much does this weigh" "two ounces" is older than the concept of mass (well, older in greek probably), thus it means newton or whoever simply had it backwards, and mis-used the existing names (weight should have meant mass as it was already being used like that, etc). Don't you _dare_ bring reason into this (again), this is about scientific prestige and and.. and stuff, okay?

very interesting, fascinating i would say, but unfortunately wrong :). many people are guilty of exactly what you described (but not that many: i was a "victim" of the stain problem of the early k-5, and you can imagine i was watching the threads related to that, for instance); there's also another common human "flaw": "whatever didn't happen to me cannot logically happen to anybody else, unless they do something stupid", unfortunately that kind of reasoning ignores the fact that the variance of factors at play is too wide, and you need a serious sample of experience (not just one persons, with one camera) in order to draw a conclusion.

anyway, based on my extensive and all encompassing experience, the design of the slot is "too tight" from at least two points of view: clearance between door and card (so hard to remove the card with ones fingers), and the actual size of the slot (yes, Fogel70 is right on the money imho)

depending on how you look at it, it's either very hard, next to impossible to do, or extremely easy: the easy way is "a list of everything we've ever dreamed of having for a price point where pentax would litterally pay us to buy it", the difficult way would be somebody wading through all these threads, regularly, try to make sense of them, and decide what is plausible and what not (a very slippery job, can you imagine the criticism threads about how incompetent the poor bastard was, because he missed this or that un-confirmed statement which proved to be true, or included this spec which was "obviously" (in hindisght, everything is obvious) not correct

imho, you're missing the point though: where's the fun in that, if you want boring and safe, wait patiently for the official spec in a few days (or weeks or months, whatever) :). rumors are to be enjoyed in their entire unreasonableness and insanity, otherwise it's a waste of time, it's all speculation and hear-say anyway, at the end of the day. the fact that some things might prove accurate is largely irrelevant (statistics at work)

surely, you jest, sir. every single release since at least the k100d or so has been a "wow" moment, has made people talk, etc. every time it has been some major improvement (unlike most of the other manufacturers..): k10d, weather sealing and pro build quality and ergonomics in an enthusiast body (the nikon d80 designer cried), k20d (slight tweaks to the acclaimed k10d body, brand new, at the time class leading sensor), k-7: a new body to die for, sensor from k20d (still good though not the best), video by popular demand, k-5 (no introduction here, just "wow"), k5ii(s) was the only apparent exception, though people who actually shoot them say the af improvement is _major_ (btw, af improvements have been made all along this little history, with each and every single model, no exceptions afaik). What are we expecting here, a camera that's credit card sized, takes all the lenses ever sold by anybody, doesn't need recharging, has a mind control interface and doesn't even need to be taken out to take the shot? (you'll have to be patient in that case, i hear they're working on it)

fair enough, af could be useful, but i find people make too big a deal of it for "big sensor video". i mean, seriously, we're talking cinematography here, this is no longer "home video, crappy quality, blow all the candles now boby, smile to the camera, got it, can eat the cake now". as far as i understand, you either need to leave the focus alone for a given scene, or have a very good cine-cam operator who can actually "follow focus" smoothly, etc. if they can make af that can trully be controlled, be predictable, read your mind, etc, okay, fine, but meanwhile, come on, video on "big" sensors, this is cinematography, this used to be the stuff of holywood, forget the damn af and enjoy it, it's here (if you're a cinematographer, if not just ignore it). Same goes for audio: these are gimmicks, if you want proper audio, get a proper audio recorder, the camera is for image, the integrated audio is useful only for "quick ones", help syncing, etc.

i can't help wondering if people who are _really_ bothered by lack of af during video or sound quality wouldn't be better off getting one of those (overal very nicely designed) "family" video digicams, either memory based or the great sony magnetic tape ones. they seem to be the perfect tool for such purpose.

hell, one shouldn't even change exposure during a "take" as far as i understand, if serious about cinematography, that's why cinema shots look breathtaking, while the digicam ones are just "nice" (ah, it was adjusting the exposure there, right, got it now, oops, focusing,, allright, we're baaack) -- of course, with the dinamic range on those tiny sensors, you wouldn't see anything while sweeping 20degrees on a sunny day, so exposure must be adjusted, but this is the point of using these big chunky sensors instead.. (high dinamic range, color depth, "holywood here i come" on an affordabel budget)

nokia lumia is a different animal altogether: it's designed for casual use, for documenting stuff with "what you have in your pocket", so it must do a decent job with what it packs, otherwise there would be no point. But if you intend to shoot video with a dslr (so cinema-style), you better be prepared, have the equipment you need, have a proper plan in place (what you will shoot when), and a few assistants to help if possible.

anyway, rant over :), of course "things could be better" etc, i'm just saying some things don't matter as much. if they want to do something really nifty, raw video is the trick imho (see blackmagicdesign ;) ), prolly not easy due to pipeline requirements, or maybe not?

wait, this is the rumors section.

completely unreliable sources that i completely trust from inside the outside or thereabouts non-specified strategic location lead me to believe all claims about the new k-3 featuring raw video, and writing it to two cards at once for speed are blatant lies and "they" have never ever leaked such a detailed spec so "you should not even know it exists!" (quite angry here). understandably, i politely excused myself (life and limb first, sorry). make of it what you will.

if you are not assuming you will print the entire frame (full frame, sic), from both the aps-c and the 35mm sensor at the same final size, discussing depth of field is meaningless. if you don't settle on some reference output (usualy described by circle of confusion, which is the "ellegant term" to describe something like "printing at the same reference size, without cropping, looking at the result from the same reference distance with the same pair of reference eyes in the same light"), depth of field is meaningless (read: it does _not_ exist). Depth of field is an aproximation (an expression of what we cannot see/distinguish), strictly speaking, there is no depth of field, and the focus point is only one.

btw, megapixel count has nothing to do with how big you print the picture, that seems to be a common misconception (it can help, but it doesn't dictate it); hint: have you ever seen a billboard print (those huge highway ones) from up close? what do you think it will look like seen from 2-3m (4-6 feet)? ;)

i thought af for video was exclussively for those nasty little video digicams designed for lazy "amateur videographers" who want to shoot their kids at the pool and can't be bothered to focus.

now, this is really not a cooperative attitude, is it? surely there must be some you can spare? really nice clean cuts, i promise, nice sharp blades. be a team player and all that, for the greater good and pedagogical purposes :P

/me shudders at the thought of actually cutting where there's some data, and walks away "this joke has gone too far"
