7D High ISO Performance

[mike_haycock1]

Hey guys,

Love reading through the forum here, a lot of good stuff. My question

is in regards to the 7D's High ISO performance. I'm kinda looking for

comparison, I know this is a Minolta forum, to Canon and Nikon. I

understand that some of the suggestions may be swayed here, but for

the most part I think this is a pretty fair forum. Concert shooting

is my main concern right now with ISO performance. I do have other

questions, but I'll just wait for those. Thanks guys.

I put a page up on my site with some 7D shots at various ISO's: <a href="http://www.1point4photography.com/7D.php" target=_blank>http://www.1point4photography.com/7D.php</a><br><br>

 

The only other DSLR I've used extensively is the 10D. I don't have the 10D anymore, so I can't do a direct comparison, but I think the two are pretty even. The 7D might be a bit better at 3200. <br><br>

 

The 7D does have a few lowlight advantages that are hard to come by in other DSLRs; the anti-shake can give you a couple of extra stops and the vf is big and bright for manual focus when af fails. I've only had mine for a week, but I'm impressed.

Question, with the AS feature, do you still need such high ISOs? Can't you use a lower ISO and compensate with a longer shutter time?

Mike, here are a couple ISO 1600 pics taken mostly with the 135/2.8 (couple with the 17-35G) that are along the lines of concert pics (circus pics) ...

In reply to the last q re: AS ... motion blur can be effective in performance shots, but you want the option of minimizing it, too, with as-fast-as-possible shutter speeds. The 135/2.8 is a little gem for this stuff, too ... a 200mm equivalent FOV and a little lens that's smaller than the 28-75/2.8.

Dennis, I apperciate the anwser. Thanks!!

Dennis, AS will not eliminate motion blur. An object moving across the lens' field of view will still appear blurred. AS will only eliminate hand shake. Therefore, my question is still valid. Can you get away with lower ISOs and longer shutter times? Or, is the fact that you may not want longer shutter times because of motion blur the reason that you want to use high ISOs? I guess the answer will depend on the shooting situation.
