We are pretty new to the concept of mounting stills lenses on a video camera (still seems like an odd thing to do, to be honest). In any case, is it possible that the lens requires power in order for the Iris controls to work? That doesn't seem to make much sense to me, but I suppose it could explain the fact that the iris blades do not move while mounted.

No replies? It seems like everybody is just as baffled as we are. The only thing I can think is that it's a problem with the lens (or some kind of issue with the conversion)... but as stated, the Iris is indeed opening and closing. It just doesn't make sense!

We are currently working on a corporate shoot, where we decided to mount a Nikon ED 17-35mm lens (f2.8) on an EX-3 using the MTF mount converter. For some reason, however, we loose iris control with that setup (and that setup alone- other lenses work). The lens is flat stuck at 2.8. It's a completely bizarre situation, as the iris IS being closed down (we checked it). But the amount of light entering the camera is not changing. At all. It's almost as if its breaking the laws of physics. Does anyone have any ideas of why this might be happening?

That option is also on the table. However, we also want to maintain the "warm" look that super 8 can give. In any case, the question pertains more to the procedural issues of mixing a DigiBeta signal with other video standards, and the issues that may arise from that.

I am currently working on a film that will combine Super 16 footage with video footage. The idea is that certain sections of the film are told through "home video" footage. As it currently stands, we will telecine the S16 footage and finish on DigiBeta. In terms of the video footage we have come up with the idea of shooting the "home video" sequences on Super 8. We will then project that footage and capture it with a DV camera (most likely a DSR 500). This, we hope, will give us the combination of film/video look that we are striving for. Does anyone have thoughts on this? Or perhaps a more effective way of achieving the same thing?
