I've been shooting my daughter playing high school and club volleyball for three years now and I'm still looking for the perfect lens (or set of lenses). The lighting is anywhere from terrible to worse and I'm not happy with a lot of motion blur on the ball or the player's hands (fastest moving bits). Therefore, I usually want to shoot at 1/1000 (doesn't quite stop the ball on a spike, but close to sharp on most other moving bits). I have the 1Dx and can live with the noise up to ISO 6400, but really see a drop off versus even ISO 3200. I have been shooting with the following lenses: 85 1.2L II (the fastest aperture, but slow focus - works well for following one player but not the overall action, focal length is about right for most venues where I can walk along the side of the court); 70-200 2.8L II (ideal choice in good light - I rarely have good light); 200 2.0L (great lens, a little too long a focal length at times, but get beautiful shots when the lame photographer can keep players in the frame). My question is about adding the 135 2.0L and it's performance in terms of IQ, AF etc.... From viewing the ISO charts on this site, it seems just a little less sharp and contrasty than the 70-200 II at 135mm (2.0 -vs- 2.8), which might be good enough for my purposes (95% of shots just posted on-line, 5% processed and printed up to A3 size, but I confess that my own satisfaction comes from as perfectly sharp an image as possible even if I am the only person to ever blow it up on the big screen high res monitor and go 'wow'). So, 135 f2 - sharp enough? Other lens options? (I sold a canon 100 f2.0 b/c it didn't satisfy my IQ requirements.)
I wished for a 100mm f1.4L w IQ like the 200 f2L, but Santa Canon did not deliver - yet.....
