It's noticeably better at 6400, and better still at 3200 (duh). The 50D is slightly worse than the 7D at those ISO's. I'd love to be able to shoot at 3200, but it just isn't going to happen at these stadiums, although I did drop to 6400 near mid-field at Seacrest. What is acceptable depends a lot on what you'll be doing with the images. If you use some good noise-reduction software, 12800 is perfectly OK for facebook-sized photos, because the downsampling tends to average out the noise. For large prints, it sucks.<br /><br />One thing I've learned the hard way through my event photography (both sports and speakers) is that shutter speed is king. A photo in which your subject is blurred because they're jumping or gesturing or whatever is worthless, because you can't do squat about motion blur in post. You MUST achieve an adequate shutter speed at all costs. Once you've done that, then you can start worrying about trifles like depth of field or ISO noise. ISO noise can be compensated for (to some degree) in post. Not so with motion blur.<br /><br />For fast-moving sports (high-school level & above), the ideal settings are to get shutter speeds around 1/1600s, a tight depth of field (f/2.8), and the best ISO that those settings will allow. In dim stadiums, I had to max out my aperture (f/2.8 or f/4) and my ISO (12800) and just take whatever shutter speed I was left with (1/500s). I'd consider that the absolute slowest shutter speed for football. I'd rather underexpose on the field and brighten everything in post rather than shoot any slower than 1/500s.<br /><br />Hope this helps.Obi-Wanhttps://www.blogger.com/profile/15191019726892983113noreply@blogger.comtag:blogger.com,1999:blog-3652457072960239076.post-3447556023413566252013-11-16T10:28:36.668-06:002013-11-16T10:28:36.668-06:00Thanks for the detailed explanation of your night ...Thanks for the detailed explanation of your night of shooting, it answered a couple of questions I have had, especially about the 7D's iso capabilities. I have yet to push it to it's max and have never gone beyond 3200 for fear of the noise factor but will experiment with a little higher numbers if needed next time.pookiepeahttps://www.blogger.com/profile/08956470749605369401noreply@blogger.com
