Originally posted by dgaies Agreed. The K5 produces excellent straight images out of the camera that don't require any NR manipulation. Images up to 6400, if shot and exposed well, don't require much of anything. Even images at 12800 and some 25600 images often just need a quick pass of light NR, which only take a minute or two. And yes, at 51200, you probably need to put some time into the PP to get a decent image noise-wise (John, please chime in and correct me where/if I am wrong). However, my understanding from speaking with John (who owns a D700) is that from a noise perspective, this is no different than the FF (albeit from FF sensors that are 1-2 years old at this point).
This is all very comforting for someone who does a lot of wildlife/bird photography in often not-so-good lighting conditions.
Even with underexposed images, done inadvertently, we can now assume that it is possible to get decent results at much higher ISO's than with the K20D/K7.
On a cloud covered day, even with some mist and/or rain, especially late during the day, the available light isn't very good. Unfortunately, these are times when one can actually encounter lots of wildlife, especially water birds near/on shores of rivers and lakes.
Same goes for early mornings with a misty atmosphere and low available light.
Contrasts are just not there and I usually have to crank up the ISO way beyond what the K20D/K7 can properly handle, keeping in mind that a reasonably fast shutter speed is near always needed.
(I can imagine what this would do to the K5 AF as well, but that's another story).
This is like a dream come true, I just need to get my own K5 .... sooner than later.
Thanks for all of the images shared.
