Don't forget that there were two different silver Konvas designs, the 
one built by KMZ and the one built by MosKINAP:

Also, from what I understand (I've never physically seen one), the 
Ostcam has a capping shutter (or at least a capping shutter attachment) 
making it light tight. While both the older silver Konvas and the newer 
1M and 2M Konvas have the standard rotating mirror designs.

My K200D Pentax has a setting for a wider dynamic range, but it raises 
the minimum ISO from 100 to 200. I'd assume that the other major DSLR 
manufacturers have something similar. That, along with shooting in RAW 
modes might not be quite the same as film, but I wonder how it compares 
overall? Could the average person notice it when projected onto the big 
screen?

I haven't done any tests on my own, but I have seen a few tests of the 
wide dynamic range done with the K200D online. Looks like it could 
possibly be getting at least a 1/2 stop extra (maybe even a full stop), 
but... I wouldn't bet my shoelaces on it. ;-)

With my Pentax, I've also been using a few of my older, manual M42 mount 
lenses. Since they are older and much heavier than the modern plastic 
lenses, they feel more like Cine lenses than they do modern plastic 
still lenses.

Do you mean the Sony A900? The new 25MP studio oriented camera? Nice rig 
- but it's a little pricey...
