SMALL PICTURE NUTS AND BOLTS WISH LIST FOR DSMC
1. Have sensor chip mounted on symmetrical frame perhaps made of a nickel alloy similar to Invar. This is to mitigate thermal movements in X,Y and Z. (very important for precision work).
2. Provide plenty of surfaces to bolt onto. We need rigid mounting so we can maintain 3 arc second precision in 6DOF. Not even industrial cameras adequately provide for this.
3. Removable chassis. The enables further 3rd party engineering. It takes a lot balls to put leaf digital camera back into a CNC vice and start cutting!
4. Narrow form factor, this makes it easier to get good close up stereo shots such as peoples faces. Interaxial separation of 8cm between two camera would be nice.
5. Sensor size probably not to be larger than 35 by 48 mm, as this will include the largest number of possible lenses (at least from our point of view). The new leaf 56MP backs are approaching 60x60 mm formats, which leaves one reaching for older lenses.
6. At least if the system physically breaks down to an open sensor, like a digital back then people have the option if the want to go range finder and use Biogon/Scneider/Rodenstock wide angle low distortion lenses, or if they want a mirror box/prism that can be bolted on and folks can use their distagon type primes i.e. Hasselblad (depending on provided shutter mechanisms), Mamiya etc.
7. For FX and other works such as 3d, would nice to make sure the system can be mounted on rail system so one can pull focus, and use the same type of filters and matte boxes that the cinematographers are using on set, so that it is possible to match color and contrast for special process shots.
8. For special process work 2d or 3d (as you know) when you have 4K final output, in my opinion it is absolutely necessary to have a higher resolution acquisition system so that in the final composite you don't get artifacts that manifest themselves as textural differences as a result of under-sampling. A 48MP sensor would be very nice (indeed)
9. Simple methods to easily synchronize (time wise) to the pixel, multiple cameras from two to 10, enable complete remote control so the action of physically pushing buttons on the camera does not upset precision adjustments.
I know, its a rather greedy wish list,
