Re: 60D Video-High ISO
 

The 7D will allow ISO 12,800 in video mode. The 60D won't.

I used 12,800 once, in testing only. If I had to use it, the choice being 12,800 or no video, I'd use it knowing that I'd have to "live with" a fair amount of easily visible noise. The only test that showed almost no noise at that ISO was on something that was evenly lit enough there were no dark areas or marginally lit areas.

In your situation I would purchase the EF 28mm f1.8 USM prime lens. Not inexpensive by any means but close to an absolute miracle worker in marginal lighting situations. Perspective is "normal", much like we used to "settle for" in the 50mm lens most film SLRs came with before zooms became so popular.

This lens is your best solution if you don't want or can't go supplemental light. I have it and for video it is one of my favorite optics. Two others I use for video are the EF 24mm f2.8 ("wide" normal) and the original metal barrel EF 50mm f1.8 (portrait tele perspective).

Hey Dave....

May I ask, where do you use a DSLR for ENG work?
