high shutter speed vs. performance in K3
Posted By DBGrip

Have you noticed differences in contrast or color vibrance say 1/500th vs 1/4000th?

Shoot outside, pretty wide open, on primes is the situation I''m thinking of. Live event so I'm not worried about getting a fast enough shutter to freeze action. I did shoot this event last year with my K20, and am just trying to make some self improvements this year. Two bodies is going to be a good start.

Thanks for your input, I'm going to go look through my shots from last year, and see if I notice anything. Was wondering if anyone had tested it, maybe I'll do it this weekend :)

Again, I'm just assuming there has to be a difference with the duration that the sensor "views" the scene.

high shutter speed vs. performance in K3

I've read a bit about slow shutter speeds and performance with regards to sharpness, color depth etc; but I haven''t found anything about high shutterspeeds with the K-3, or K20D for that matter.

I want to know is there a shutter speed where the sensor in the K-3 starts to lose performance just from not getting enough time viewing the scene? 1/250 th vs 1/5000th say? I'm try to ascertain if there's a point I'd rather ND to maintain aperture setting rather than speed up the shutter.

Lenses have aperture sweet spots, zooms have focal length sweet spots, just reasoning that there's a shutter sweet spot for bright exteriors.

If so, is it different for the K20 (my other body)?

Thanks,

Rob

Put it to a tough test...that moment between night and day. Tiny lightroom exposure grad to check detail in bottom right corner. Need to learn about HDR more, this might have been a good instance to use it...

Get the K-3...just upgraded from K20D. It's fine for video, if you don't auto focus. Screwdrive is loud.

K-3 has the DA 35 2.4 "plastic fantastic" on it (just got it, putting it through its paces)
K20D has the FA 50 1.4

Thanks for the info. Sorry it took a while to reply been out of town... This would be my first time taking apart a lens, and have read some of it on here. Do you know of a good place to start looking for a specific walkthrough for this lens or something similar?

That's my hope! would you put wider primes on the K-3, and longer ones on the k20 (theory being more room for cropping/zooming with more MP)?

I too, just took advantage of holiday pricing, and upgraded from the K20 to the K3. Luckily the body had had its firmware pre-updated. I love it, and you will too. Everything that bugged me ergonomically about the K20 seems to have been addressed in the K-3. That front dial and the AF button feel WAY more natural. Getting usable images at 800-1250 ISO has been great too. Hope you get your issues resolved soon, so you can start enoying it, as well. I've loved my k20, and as I acquire more primes, I'm going to play around with using 2 bodies.

I have this old Hanimex, and it's become one of my favorite lenses over the years. I stepped away from photography for a while, I've recently started re-exploring some of my old lenses, and discovered a little fungus starting to grow on this lens.

I'm having trouble finding out more about this lens on the interwebs, Serial number is h52040. I've found out many companies manufactured for Hanimex, as was wondering how to find out more about this lens, specifically how to take it apart ant clean this inner element.

Thanks for any help

Are SLRs dying?

No... This is the key point, I think. It's not telling you what you are seeing. The EVF is telling you what the camera is seeing. And that's a good thing, because it's the camera that has to capture the image with its own sensor. It's not your eye, or your retina, that takes the picture. If I want to know what the scene looks like to my naked eye, I can always lower the camera and look. If I want to know how the camera is interpreting it, then I need some kind of electronic display. It's helpful.



You just made this whole argument resolve for me just why DSLR's aren't dying. It clicked... the OVF is telling you what the lens is seeing, the EVF what the sensor is seeing. The medium behind that format is different, I've had a few bodies behind some of the same lenses. I want to look through the lens, I'll figure out how to record it later. I'm not going to deny there are many benefits to having a screen that accurately displays what the sensor records. I imagine the first truly color accurate to recorded output screen would be the one on the back. Why give up the ability to have BOTH? That's why DSLR isn't dying, because people will want to look through their lenses, and see reflected light, not projected light.

Next step in sensor technology will be making them translucent, so we can drop the mirror and look straight through the sensor, through our lenses. OVF Forever :) EVFs are what reference monitors are for :) Why waste that OVF space?

I'd rather have a 7" monitor mounted in the hotshoe, than pretend that the tiny video screen I'm looking at through a hole is actually looking through the lens. I understand the reasons EVF's could assist in some cases. However no sensor, nor film for that matter has the dynamic range of my eye. The viewfinder is for framing. Call me old fashioned but in MOST applications if I'm hunting for the shot I want to look through the lens. I can tell which of my 50's I'm looking through, when I'm actually looking through it, I can't in Live View. Skill in getting exposure and tweaking exposure, through experience, meters and eye, is what makes one a photographer, the more mystery that gets taken out of it, the more the craft deteriorates, and the more the skill gets devalued. Can't "feel" focus by wire.

Mtngal, try throwing on a CPL to deal with the reflections in museum, main draw back being the need to come up with another stop and a half or two, potentially. Sucks to lug around a tripod, but...
Lastly, a black handkerchief thrown over the camera body at the last minute can make things disappear.

I get it. Thank you for the suggestion. I ended up running some tests on that lens today, and used live view on a tripod to check focus, and also to double check my diopter. I'm hoping the 27 vs 9 pt AF system works better. The focus marks on my 17-50 are way off 3ft read about 6 ft, 1.5 ft was just shy of 3. I plan on trying some landscapes and long exposures on my trip I can see using live view and punching in will be useful with my manual lenses.

Thanks for the tip.

And take my eye out of the lens !?!?! :) I tried it once or twice on my K20 and didn't feel it, but I usually hand hold my camera. I could see where LV would be a benefit for tripod work, I imagine you can punch in for focus, especially with manual lenses. I'm going on a Florida trip this weekend, and since we've rented a mini van, I'm taking EVERYTHING, including the K-3 I can't touch til Thursday. K20 is coming along too, as are the old lenses. Going to play a lot. will give live view a whirl.

I've mostly been using the 17-50 handheld, Auto focus, chasing the kids around mostly with some "posed" (they're 4 and 1, still have to keep the finger near the back AF button), and some concert/journalistic shots. I thought it was softer than I expected, but noticed that focus has been off, sometimes front, sometimes back. I notice these problems mostly at the short, open end of the lens. Hoping that the improved AF of the K-3, might make a difference. I guess I should search the forum for a good tutorial on lens setup/ testing and put it through its paces before going away. I really wanted that lens to be my "walk around". Maybe I have a bad copy.....

Or maybe that 70-200 is just so damn awesome, it makes the 17-50 look shabby (it's warmer too, I think). :) Thanks guys.

Though I'm still figuring out digital still photography (mostly internet reading, and trial and error, mixed with scattered periods of life of being an entusiast), I'm around motion picture photography every day. I'm new to the forum, and I've recently learned that my monitor is not the best (but doesn't suck) for properly viewing images, I try to look at photgraphy in sRGB mode to get as close to a standard where I can see what the photographer intended. I flipped through the other modes and it totally changes the look of everything. Now that I've disqualified myself from any point of authority, here's the advice:

I'm not even going to talk about post, because that is totally subjective, but necessary if you shoot RAW. For a landscape such as this, shoot more frames. Change some settings, and shoot different exposures, and shutter speeds. Not knowing your situation (handheld/tripod), I see you're at a low ISO 125, relatively slow shutter, and almost wide open. If you're handheld, ISO is your option to change. (i'm still wrapping my head around EV adjustments, and stick to film principles) shoot a frame at 400, 800,1600, and you may end up with a better starting point. With a tripod, you can get into real slow shutter speeds, and start playing with apetures and filters, a polarizer might have pulled out the cloud detail before heading into post, or a top grad to balance out the frame, for that matter, but you'd have to slow that shutter down. It seems to be a great situation to have played around with HDR as well

A theory, I've recently learned and so far seems to help, is in digital to try and get your histogram shifted right and introduce more contrast in post. This one has been tough for me, as I like high key ratios, so if the opportunity presents itself "bracket" your shots, the more you do it, the more it will become natural.

I need to figure out how to put up some of my shots, and open myself up to some criticism, it's only fair :)

I like it. Compositionally. The way the tree silhouettes. The grass is a little dark for me.
I have confidence problems in PP myself. How much is too much? Sometimes I end up with 4 versions of the same image and can't decide what's best.
What PP did you do? Radial filter? Left Grad? It's hard to tell without seeing the original

How's the scanning process with the v500? I had bought my dad a slide and negative scanner a decade ago, to digitze basement boxes full of slides and negatives over a decade ago. It was too complicated and he never did it. I have a v500 and have thought about trying to take over for him. I believe some of my early work is mixed in :). Your story resonated with my own experience, including the reaching a plateau he was quite happy with. I had to learn with the Honeywell Pentax full manual, and a weather beaten Sekonic dial meter, before I could use the new ME Super :).
