Originally posted by pxpaulx While an f2.8 constant Aperture lens is ideal, with the K-x a quite useable ISO6400 makes even the kit lenses a viable option for someone on a budget (considering the 50-135 or 70-200 F2.8 options run just shy of $1K on their own).
It would have to be head and shoulders above my K20 at higher ISO's to be real usable for decent sized prints. I have been only marginally happy with the K20's performance in the upper ISO range. (hence the thread that I started last week).
The f/2.8 also gives you a very good DOF for those great sports bokeh shots. You need those to isolate the subject at times, especially when the BG is not appealing in the first place.
And at some places you just don't have enough light during evening games to shoot with a slower lens.
The problem with getting a camera is that is the cheapest thing you will buy... then comes the lenses... then you realize that you need this or that lens and you spend more... and looking back the camera was a cheap "starter drug"...
About the size of the new bodies, I actually like the larger size of the K20. Not that the *ist or K100 was uncomfortable... but I do prefer the bigger grip. I bought a battery grip for my film *ist because it was so tiny. (that was a nice camera!)
There are plenty of ways to work around all the problems... the bad thing is that most take money... and the best ways take the most....
