I ran into a whole mess of difficultly due to some lens flare problems that caused a blown out spot in the center of the image and horrendous flickering on about 25% of my footage. Correcting it took forever and the results are not that great, but I'm happy to have it done. I didn't think it would even be usable for a while. On the bright side, I now have some tricks for completely eliminating really horrible flickering from footage.
I used a variety of nikon 35mm lenses on the camera and i've decided that I'm never going to use them again on 16mm film. I can't seem to reproduce it every time but there seems to be something with the rear element being really big and the mirror reflects light back onto the film. It mainly seems to be happen when there's a bright light source in the frame.
