I used my k-7 regularly at 800, but there was a noticeable loss of quality. I have more than a few that I shot at 1600 that turned out ok, but I don't know if I would try to print them poster sized. For people shots and coverage, 1600 was fine for just web and 8x10s especially. With the k-5, iso 1600 looks amazingly good. Better than iso 800 on the k-7. 3200 has some grain, but in a pleasing way imo and black and white conversions look good...especially with silver efex. I was reluctant to use 6400, but when I started trying some portraits with it more with black and white intent I was surprised. It looks really darn good. I wanted a k-5 for a long time. I bought a used k-7 and took enough pictures to make some cash and I bought a k-5. I'm pretty amazed at that sensor and what it can produce. I use a 5dmk2 for some stuff at work, and the shadow noise is really awful in comparison. The greater DR helps a lot too. You really have to blow the sky pretty hard to make it unrecoverable in raw. Best part is you can just totally expose for the sky and push your shadows 2 or 3 stops pretty easily without hardly any noise near base iso. On the flip side I preferred the k-7's contrasty bite the files it produced had. it was almost film-like in tonality to me. I liked the vibrant colors I got off that sensor too, where the k-5 seems a tad bit more muted, or maybe its just me. the k-7 seemed to nail tungsten WB better too. anyone else ever notice that? the k-5 gets pretty warm and hot fast.
