Lens Mounts for Epic

[Eric Ulbrich]

It'd sure be a nice system. Swapping mounts may take only a minute, but if collimation takes significant special equipment and time... it's no longer a viable production move.

I hear that. I worked on a cinealta feature a few years back. The 1st AC for both camera units each carried a field collimator and calibrated through the day. It must have driven them nuts

If it could move in the x-y axis as well, like the sony dslrs, you would have internal image stabilization or for special effects an explosion shake button.

By the way, if you have never seen the sony IS where they actually move the sensor it is amazing to watch, they had a demo at one of the circuit city stores and I was astounded at how far and how fast the sensor moved.

I'm sure there is a youtube somewhere.

This surprises me for a different reason. It means that the lens will need to cover a much larger area than it would have to if the sensor didn't move. So if you are applying this to an APS-C / S35 sensor, for example, you might need lenses that cover FF35...

It's pretty impossible to change the lens mount on a set... That has to be done by a camera specialist who knows how to do it and can set the back focus well.
Interchangeable mount is probably a good idea for Scarlet. I don't see the real need for interchangeable mount on the Epic S35. Because of it's price level, that camera is going to be owned mostly by rental houses, these people have plenty of PL mount optics. I would suggest to make the Epic S35 PL mount only and have the mount very robust, a steel mount would be nice.
The Epic FF35 sensor seems to be as large as the Dalsa Origin sensor. I think Dalsa modified some Leica prime lenses for getting a full image on their sensor. I'm not sure the type of mount they use on the camera.

Dalsa uses (soon used) a PL mount. They designed some lenses to cover the full image area of their sensor, which while larger than Super-35 was still considerably smaller than FF35 (which will forever be known to me as VistaVision).
