I am currently planning a camera projection which involves zooming in from medium closeup [head/shoulders] position to extreme closeup onto an actor's eyeball. For those that do not know, a camera projection is a visual effects technique which a still image is projected onto computer-generated geometry so that you can regain parallax when a virtual camera is placed into the scene. As a result, for something like this you'll need a pretty high resolution image so that when you get up close to the eyeball things remain sharp and un-interpolated. I'd like to do it all in one shot, that would be preferred for simplicity sake, so I am looking to rent a 5Ds. I could probably do it in steps, but there are real significant complications with that. The next question would be lenses. What lens would you recommend that will perform well at 100% viewing? I'd like to use something in the 80-135mm range. Price here is not so much a concern since the lens will be rented only for a few days.
