Originally posted by kevbirder I'm considering getting a K-5. Currently I have a GX-10 (K10D).
Mostly I use a manual focus 400mm Sigma lens for bird photography.
Solution (part solution anyway) was to get a new focus screen at great expense from Katz Eye.
I use a focus screen from these people. Firstly in my K7 and have now moved it into the K5. Excellent service, great price and tools (though price has risen since I bought mine) and a great choice of screens :
Focusing Screen Originally posted by kevbirder Does Live View make all this redundant? i.e. stop using the viewfinder and zoom in to focus? I guess not for birds in flight etc.
I never use Live View for birding, far too slow and the shutter lag just makes it worse.
Originally posted by kevbirder Another question is whether I can expect auto ISO to be any use on the K-5. It's hopeless on the GX-10, there seems to be no way to set the shutter speed at say 1/500th, set the aperture at f8 and let auto ISO do its thing.
I use the TAv setting about 70% of the time (MF the other 30%) and it is brilliant. Set your shutter speed and aperture and set the maximum ISO speed you want. Note though that with MF lenses the camera defaults to AV mode.
Originally posted by Ron Kruger Before the K5, I used MF for at least 90 percent of my shooting. However, the K5 has the first AF of any camera I've used that I feel I can trust. It is really fast and accurate with all my lenses (primes). I probably should qualify this by saying I haven't tried it on wildlife yet, where AF can often center focus on leaves and limbs instead of the intended critter, but I've been so pleasantly surprised so far with the K5's AF, I think it might work for wildlife as well (just in time for my failing eyesight).
I think the answer is to use a quick-shift. I use the DA*300 for my birding and quickly AF on the general area of the bird and then use the quick-shift to manually focus on the bird rather than the branches.
Originally posted by Ron Kruger There are still times, and will be times, however, when I'll want more control over the exact focus point and the hyperfocal range, and I'm afraid the K5 makes that more difficult; not impossible, but it requires even more concentration. I tried a Katzeye on my K20D and didn't like it. I'm considering a magnifyer eye-piece for my K5 instead.
As my eyes are poor I have the magnifier (helps a little) but IMHO MF isn't that difficult at all on the K5 - so long as you are not trying to MF at f1.4 ! Though naturally there are fewer keepers than with AF it does allow me to use some beautiful lenses. Have you tried using the CIF for your MF lenses ? It enables me to get shots I could never get otherwise (shooting street - cyclists for example). You need to enter the 'zone' relatively slowly (compared to AF) and know with each particular lens whether sharp focus is best attained focusing from near to infinity or from infinity to near.
Sample CIF shot. Contax Zeiss 85/1.4. Probably at around f2 and 1/500.
Originally posted by Darren all of this can only work if the camera knows the focal length which is why you may have issues with a manual lens.

When you put a MF lens on the K7 or K5 (and I assume other Pentax cameras) the first thing you see on the screen is a menu to choose the FL of the lens - so that should never be an issue unless you forget to set it (and then it defaults to the last length you set) !
