I can also see A LOT of people talking about razor-thin depth of field... in my opinion the depth of field in the latest 5D videos is TOO THIN. Yes, there it is, I said it. Too thin. If you can, it doesn't mean you should. I can't undestand why people shoot with f/1.4 , f/1.2... what's the point? Everybody who owns a 5D Mark II tries to shoot EVERYTHING with shallow depth of field just because they can, not because there is a reason for it. I was looking at Philip Bloom's blog the other day, he's got some nice footage but God he shoots everything at f/-1. Even the stills when showing some piece of gear are shot using 1mm shallow depth of field (example here is an example (http://philipbloom.co.uk/wp-content/uploads/2009/08/IMG_01531.jpg)).
As others said, RED one is similar to a 1.6x sensor. Also, when shooting film you have the depth of field similar to a 1.6x sensor.. so why do people complain? Oh, I know: you won't feel your footage is good enough if it's got more then than 1mm sharp? :doh:
The DOF is going to be the same on the 7D as with the 5D if you are using the same Canon F1.2 lenses anyway. If somebody chooses the 50mm 1.2 over the 85mm 1.2 then the perceived DOF will be deeper (even though technically the DOF is the same between these two lenses but thats a different discussion)
I don't see why you should go for a smaller sensor just because you have the ability to get very shallow DOF with a larger sensor. Either choose wider lenses with 5D, stand further back or stop down your aperture. I know that stoping down your aperture will cause you to loose some low light capabilities but the larger sensor is probably giving you about 1 stop of room to boost the ISO over a cropped sensor anyway.
Yes, some people will shoot closeups at 1.2 but that will just make your footage look better because you don't do silly things such as this. Personally, if I had a choice between a 50mm 1.4 on a 7d or an 85 f1.4 on a 5D, I would rather shoot with the 85 @ f2.0 and ISO up 1 stop with a 5D then with the 50mm wide open and a lower ISO on the 7D. Framing being equal the 5D will have a bolder image because you are using a longer focal length which pronounces the background and you are shooting at a sharper aperture with the 85mm lens. The only good thing about using the 50mm on the cropped sensor is that you are discarding the edges of the lens which is the worst part optically.
