I'm buying Redrock m2r and I have a question about which lens mount to get. You see, I also own a Canon EOS REBELXT and I'd like to be able to use the same lenses for both. But Redrock cautions that because the EOS is electric, you don't have the ability to close the aperture down unless it's hooked up to a 35 mm camera body. It goes on to say that regardless, they've seen some really good shots this way. My question is this, should I just live with the fact that I gotta buy two diff brands of lenses, the canon's for my canon, and probably some cheap Nikon's for my DVX Redrock adaptor ? (I just love writing that). Or should I get the EOS lenses and figure it out? I hope somebody knows what I'm talking about. Thanks. LJ.

I can't say for sure, but I'm guessing that exposure control with the M2 and EOS lenses is done strictly with the aperature on the DVX. If that in fact is the case, then you won't have any way to control your depth of field because the EOS lens will always be wide open. That would give you less depth of field, which is one of the primary goals of the M2. But, of course, you would't be able to increase your depth of field.
My suggestion would be to buy the M2 with a mount that takes standard lenses. You might want to consider Olympus OM lenses, as they may be cheaper than Nikon but just about as good if not as good. Not sure though.
And if I'm wrong on any of this, someone please chime in and let us know.

I faced a similar decision... had a couple of Canon EOS lenses, and yet still went with the Nikon mount on my M2. With the Nikon mount you are pretty much guaranteed that every Nikon lens for the past 40 years will work. So maybe you should sell your RebelXT and pick up a Nikon D70.

I read that the succesful use of those lenses required removing the lens from the M2, attaching it to the still camera body, setting the aperture with the camera, and then returning the lens to the M2. On the one hand, this workflow sounds awful -- swapping lenses to change the iris setting. On the other hand, you probably won't be changing the aperture that often. The reason is that you will probably want a shallow depth of field and as much light as possible coming into the M2. So you would naturally leave the 35mm lens as open as possible. And you want the best focus you can get from the screen back to the video camera. So if you have extra light to play with you would naturally close down the back iris in the video camera to control exposure and get better focus on the screen, rather than close down the front iris on the 35mm lens. That means resetting the 35mm iris is probably an aesthetic choice to control depth of focus and not something you have to use to control exposure.
I didn't have any Canon lenses, so my choice was simpler.
