Originally posted by Singinman I anticipate much better shots of my granddaughter's basketball games this year.
If the K30 is similar to the K-5 it should be at least one full stop better than the K20D, up to 1600 with few visible noise. 3200 and 6400 are quite usable with a bit of NR. 12800 to 25600 are not recommended but can still produce good results with lots of NR. The great thing about this sensor compared to K20D/K-7 it's the absence of any grain pattern (horizontal or vertical) and no color shifts or blocked shadows.
The K30 will also benefit from a faster AF system and faster burst than the K20D.
