Yea, I noticed that yesterday too. And the sheer quantity and virulence of the vitriol hurled at Pentax isn't necessarily a bad thing. It humanizes the company while getting it a lot of publicity. I don't think all the borderline autistic camera techophiles really understand how smug and off putting they are to normal human beings who just want to take some lousy pictures.

A super-technical camera like Fuji's X Pro with it's DOF scales, tiny buttons, and anonymous greebles and nurnies is their idea of a wet dream, but to most people it just looks complicated and prohibitively expensive. Not to mention that market is already ridiculously saturated. Pentax is trying to broaden its base of consumers -- and a good way to do that, is offer something no one else is.

:lol: You should get a film camera, thousands of shots from a single battery! (assuming they are up to your high aesthetic standards)



I welcome discussion. You thinking of starting some?

AF confirm innacurate (confusion)

Contrast AF will always hunt becuase it when the subejct is OOF it doesn't know whether it is front or behind.

With phase focus it does know so theoretically there should be any hunting. Of course in practise there is a degree of hunting, but in really good light it zips straight there.

Autofocus: phase detection


Autofocus: contrast detection

LumoLabs: Pentax K-5 low light focus study is published

Yes, the hypothesis needs more data. There seems to be some lens dependency indeed. Which is strange enough in itself, actually. My hypothesis is compatible with the limited data I had. If anybody knows about a lens pair where the slower one jumps later (so to speak, meaning, doesn't have the focus shift while the faster already does), then this would be a very valuable contribution rejecting the max. aperture hypothesis. After all, it may be a false path...

Maybe, the AF assist light behaviour (single or multiple engagements) is lens dependent rather than camera dependent. Could be another important clue.

Moreover, I think that maybe the K10D struggles in low light as well. Unfortunately, I could not repeat the test for other cameras or brands. Nevertheless, I would be surprised to learn that focus for the K10D jumps in such a binary way when the light is dimmed.



It is 1.01.00.05 (1.01). I heard that the 1.02 doesn't improve and so I didn't want to upgrade in the middle of my tests.


I am sure (from experience), I can do user errors as much as anybody else. So, please watch out for the errors I make :ugh:


Yes, and it has been subject of philosophical debates.

To make a long story short: If all humans were like you and unlike me, it can be shown we all would still live in caves. Like all other animals actually. To spread sperm (or raise children) isn't all you can do for your species, assuming a minimal degree of organization. I think that's all I say about this. But good literature about the topic exists. Thanks for your question.

20 things I learnt on my first paid fashion shoot
Posted By clark
Replies: 7
Views: 3,567
Hi, so I was commissioned to shoot a model portfolio for my first paying client, I got him to bring a female along to act as my assistant, I also took a few shots of her when my client was getting changed etc



I was shooting with a Pentax ist DL with a 50mm 1.7 and 28mm f2.8, and a Nikon d300 with a 35-70 f3.5-5.6

lighting setup was a 5 in 1 reflector to diffuse the sun/add in fill light and a tripod mounted sunpak flash unit with wireless trigger

The shoot was done inside and out, the outside shots were shot just before sunset.

the models I was working with were both brand new, and as i'm a brand new photographer I knew it would be hard work, so here's what I learned from the day's shoot.

the results of the shoot can be seen in this thread: https://www.pentaxforums.com/forums/photo-critique/111457-people-first-fashion-shoot.html

i'd appreciate some comments and critique on my work
about 600 photos were taken, of that I think i'll supply 6 to the client, and 9 of them will end up in my portfolio


so
1. I can see why they say 'Cold' models are a waste of film, don't expect to get anything decent out of the first 10 minutes, although it took me that long to get myself started too!

2. You'll have to direct more than you'd think you'd have to, getting the models to do what you want is 3/4 the challenge of fashion photography, especially when you don't know what you want them to do, having a collection of images you want to emulate in terms of lighting and poses really helps, plan out what shoots you are going to do and where- scout locations, the background is part of the photo too

3. Lighting really is key, photoshop can only do so much, and even then it can't correct a flatly lit image, getting exposure right is essential too, pulling up the exposure in RAW pulls the noise up so much

4. Get the lights up high, bounce flash off the ceiling and high mounted flash units are the key to good light, light at head height coming from the side will give an unsightly 'across the face' nose shadow- so get those lights 10ft in the air!

5. A reflector to soften the sun is 100% essential. A reflector to add fill in is also handy, but getting your assistant to hold the thing where you want it is tricky, using a reflector without an assistant is nigh on impossible unless you're doing staged shots

6. Have everything to hand, it looks unprofessional to have to disappear every 5 minutes to fetch something. Have spares of everything as well, I had a flash trigger die on me, luckily I had a spare (although it turns out the trigger was fine, the flash had just slipped a little and was loose on the mount, which brings me to my next point)

7. Know your equipment inside out, be able to fix problems in a second- if you have to stop the model will lose momentum. You need to know exactly when to use each setting in any given situation, you don't have time to keep checking histograms and the LCD

8. A 24-70 f2.8 is probably the perfect lens on APS-C, the 50-135mm would be perfect on full frame. Wide enough to cover the model and the surroundings, and long enough to get face shots. Fast lenses are essential for throwing the background OOF, if you're shooting slow lenses or at a small aperture position your subject against a wall

9. Get some tight face shots, fill some of the frames with your subjects face- you'll crop a lot of your photos down later in photoshop and you'll wish you'd done it in camera

10. The 50mm 1.7 is too sharp, even wide open- using a softer lens will save you hours of retouching. A 2.8 zoom is probably soft enough to be good for portrait, and fast enough for low light/bokeh, the kit lens works well for portraits when you're using fill in flash. I can see that softer f1.4 lenses would be perfect for portrait

11. Slow flash is an absolute pain, my flash unit on full power takes 16 seconds to recharge even with new batteries, by the end of the day I wanted to throw it off a bridge- get a flash with a decent recycle time. On 1/16 the recharge is near enough instant, but the flash only has full or 1/16 so I was kinda limited in what I could do, physically moving the flash was my only option to adjust power

12. Direct flash is too harsh, you 100% need an umbrella

13. Manual focus doesn't work for portraits, I got some great infocus shots, but 70% were off, a split focus screen doesn't help either, you have to use AF especially if you're shooting at large apertures

14. Selectable AF points, I don't know how it works on pentax, but on the d300 having the ability to select visible focus points was so helpful, i've heard that on canon rotating the camera to portrait will automatically change the focus point to the top centre, this sounds interesting. On another note having to manually rotate the PEF's was a pain too, the nikon puts the orientation into the exif, I guess the newer pentax bodies do too.

15. Having rule of thirds gridlines in the viewfinder was a massive plus for the nikon, I think any focussing screen I ever buy in the future will have grid lines unless the viewfinder has it as an overlay (like the d300/7d)

16. You can never have too many mega pixels, when you have MP to spare you can pull a portrait out of a full body shot- all of a sudden the 21mp 5d mk2 is looking tempting

17. Having an assistant is great when you know what you're doing, but it's actually a ball ache when you don't, you're constantly worrying about appeasing your assistant who's clearly so bored she can't even hold the reflector still, and not concentrating on the shoot

18. Multiple bodies is very very useful, you don't have time to change lenses- so 2 bodies allows you to use 2 lenses, I was shooting the 1.7 on the pentax for shallow depth of field stuff, and then shooting flash simultaneously with the nikon at f9

19. When you're exposure is correct there is no difference in high ISO noise between the 5 year old pentax ist DL and the brand new d300, to get any perceivable amount of benefit at high iso (with properly exposed shots) you have to go full frame

20. You can get great shots out of both systems, after looking at all the photos you couldn't tell which were which. In fact the pentax images had better noise control, and were sharper (but that's due to the lens). The Nikon does feel nicer in the hand though, although when shooing landscapes out in the field the pentax feels better, so horses for corses.



All in all I learn that having a good AF system you can trust is the most important thing in fashion photography, manual focus was way too difficult to be useful. I tended to favour the nikon for most of the shoot, using the pentax for f1.7 shooting and just to compare against the nikon, I got great images out of both cameras and i'd really like to try my next shoot with a top spec pentax camera with the 50-135, and maybe a canon 7d for comparison- because the nikon was definitely a top grade camera with great ergonomics and a great viewfinder- the k7 can't compare to the d300's finder, and the 7d is even better- bigger/brighter than the 5d mk2!!


i'd like to hear from other people who use pentax for fashion photography and what they think about the pentax AF system, and what tips they've learnt along the way



just for fun I also did a full lens sharpness test with the 18-55, 50mm 1.7, 28mm 2.8, 28mm 1.8, 28-200mm and the 50mm with a 2x tc, so I will compile the results and post them up here.

Mystery Lens Experiment (warning: lots of photos)

Many, many years all I had was a spotmatic and a tak.55/1.8 and a super albinar 135/2.8 and I could take pictures if there was money to use for my hobby. Life got better, more money brought more possibilities. But not always the time one needs. So, close to home, I often walked my bramble lane, many, many times. Many, many seasons. And took shots with many, many different lenses. And had many, many different pictures of always bramble lane. Which I still deeply love, maybe just because of it. And I learned that all these lenses have their moods, some of them are difficult (tair 135 allows for sharpness in mistlike flare) or masters in a certain color (100mm meyer - grey). some so sharp it pains the eyes (jupiter-11, well, my copy - astounding blues), and so on. They are are are so different, they walk with me my bramble lane and change it for me into different worlds. They are my companions, my poetry.

Special love goes to smc.tak 85/1.8 the only lens I have to picture the heather and the moores with the true colors brown and purple when the heather doesn't flower. The moores are always purple, even when brown.

Photography as the art of living the live I see around me. Lenses like pens to write the words I see.

FA* 85mm F1.4 and DA* 55mm F1.4 portraits

I believe I was asked to take some comparative shots with both the DA* and the FA*. Well, not really as those different focal lengths cannot be compared unless I shoot on film also (I won't), but I hope the viewers will be happy with the results below.

Today was a good day for portraits in available light. I have used both lenses extensively and at the end of the day I could not name a favorite: both lenses are top quality products, and both definitely deserve the Star designation.

I have also included the direct links to the pictures in case the picture viewer for wide pictures screws up things (you'll want to view them at 100% and not resized).

(And no, I won't measurebate the lenses; the worst thing I could do is to take pictures of newspapers or test patterns. Because I usually don't take pictures of test patterns; do you? :)
