I am going to be doing some basketball action shots soon, and just wanted to ensure I had the right equipment/knowledge. I have a rebel xt and sigma 24-70 2.8 and 70-200 2.8 lens.
I think I will use the 70-200 2.8 most of the time - the AF is really quick on it (has equivalent to USM in canon).
Shooting at ISO 800 (1600 if I MUST), with aperture wide open, do you think I will be ok to get a shutter speed faster than 1/100?
Do you guys use Manual or Av mode?
Well, I'd say that if you can't get a shutter speed higher than 1/100, then you just ought to pack it in and go home .... 'cause 1/100 won't be good enough for "action" ...
Seriously, though, shooting at ISO 1600 is what you're probably going to wind up shooting at, unless that gym is really well lit - and don't get me wrong, some gyms are really well lit ( but, apparently, they're all gyms that I never shoot in! ).
Anyway, when I shoot basketball, it's usually in Manual mode; ISO 800 or 1600 (depending on the light) and wide open at 2.8 and 1/250 or 1/320 shutter speed. Actually, I shoot basketball with an 85 1.8 or a 100 2.0, so I shoot at 2.0 most of the time. I find that in most gyms, even a 2.8 lens is kinda slow ....
If you're good with post-processing images, shoot in RAW with the above settings and just set your shutter speed at 1/400 and shoot away. You might be a little underexposed, but you can "push" that a little in the RAW conversion. Be aware that a sharp, non-blurry image with a little noise in it beats a bad, blurry image with no noise every day of the week .... so keep your shutter speed up enough to stop the action, be spot on with your focus, and "push" process the image (if you have to) in order to get those sharp, non-blurry photos.
Best of luck with that ....
