Sustained 7d video on the beach

Where in Florida? If it's in Miami may is quite hot we range from 90-93 deg @ noon. Sometimes more than that.

South of Tampa

How much of a concern is there over direct sun? I've taken plenty of pictures into direct sun but haven't seen or heard discussion on video. I would imagine canon would design the system to protect itself. The only damage I've seen is that video on lasers.

Well, direct sun is what would overheat the camera body and lens (and cause grease/oil to come loose in the lens itself, at the right temps). What I'm worried about is pulverizing my sensor with too much light over a sustained period... I've seen the laser example here. I've also read how other users did a quick video pan over the sun and ended up burning out pixels, lines, etc.

It does neither, as I said, the exposure is what matters. If it only hit the center of the sensor then we'd all have circular pictures as we stopped the aperture down.

When you put it that way, that makes sense. Still, I think I'll bring along some NDs, just for the protection and peace of mind

But now that I think about it... does it really evenly distribute the light across the sensor, or does it just focus it on the center, and reduce the concentration of light hitting the borders?

And this is someone who has 3K+ posts and is going to video a wedding?

I offered to do it for free because they opted not to get a videographer. I have never shot a wedding--it is not my cup of tea.

Excuse me for not completely understanding how light moves, but I know for a fact that light passing beyond the aperture blades (say f/22) will NOT be evenly distributed across the sensor at the instant of contact. Instead of providing any useful information, you've only succeeded in proving to be obnoxious and rude.

And thanks for wishing me a happy birthday--that is much appreciated. I can only hope others are equally helpful when you request assistance.

Are you referring to diffraction at small apertures?
