This guy has handled the 5D:
You can set the ISO beforehand but not the exposure, other than via a plus / minus exposure compensation adjustment available via the rear wheel control. There also doesn't appear to be any way to control exposure in video mode (other than the aperture (+ / -) wheel), because exposure control appears to be allocated to stills mode.
Look at his video. He has obviously has achieved maximum aperture settings with the 5D.

Forget Reichman. His reviews are a hack job for the most part. Did you see how he kept referring to the video format as 1080i ??
Hi boogerg,
Alright, I read your post (the long one), now it seems to be gone for some reason.
So I see your concern now. Hm... hmmmm....
If this is true (and it's hard to believe), then there must be some kind of video mafia or something. Maybe they have a deal with other video companies to hold it back, like the alternative energy and oil companies. I couldn't explain this any other way. It's totally stupid to force this automatic mode to such a camera.
I see three possible options:
1. Firmware update
2. On release it will be changed anyway
3. Hacking
4. Use manual lenses.
On my Zeiss 50mm the lens is not electronically connected to the canon body, so the camera literally couldn't force the aperture. I'm concerned about shutter though. 1/30 shutter is the worst that can happen to our footage (see the reverie video).
Anyway, I'm still not giving up guys. My preorder stays. I'll have a 5D that has manual mode. I believe!
If you look at reichman's video there is a shot of a train coming toward the camera with a tree branch in focus in the foreground. It is obvious the lens is wide open or close to it.
You can see he doesn't have the exposure locked down as it fluctuates once as the train moves toward the camera. The camera does not adjust the aperture, so it must be adjusting the shutter. I don't think the ISO is being adjusted. I think ISO and aperture are fixed movie mode. shutter will fluctuate if not locked down.
Dual: My theory is that Canon will introduce 5D2's technology to a dedicated camcorder. In anticipation for such a product, they purposely crippled 5D2's video capability so it won't compete with this theoretical future camcorder, nor would it compete with their current pro-sumer camcorders.
Say he was shooting at 400mm @ f/4 as that is the exposure value the camera decided, what if he wanted to shoot at f/2.8? not possible to acquire with auto functionality..
This is what Vincent Laforet has to say in reponse to this question:
Q:I think that the fact that you have no control over the aperture is the biggest disappointment. Video quality is amazing though.
from Vincent, A: you DO have control with the aperture - I just didn’t have a manual - I’ve now been told that by pressing the “*” button on the back of the camera - you lock down all of your settings (no need to hold it down either…) when you press it again - it resets… you can also change the EV compensation as you shoot - with the exposure locked down… Therefore Aperture, ISO and shutter speed can all to easily be locked down…
So that’s one “big” down - and 24 fps to goWe’ll have to lobby Canon for that and see if it’s even possible… I understand and agree that this is someone that everyone is waiting for…![]()
