okay so let me first say, that i have not built a 35mm adapter, but i have been researching the post here. I have an idea / question about the focusing screen.

okay so does anyone remember those old light boxes used to transfer 8mm from a projector onto a video camera? You place the projector on one side, then the film is projected onto a large focus screen. Then you take a video camera and film off the screen from the other side of the box.

Would this focus screen work for a 35mm adapter? my only thought is that its not transparent enough. anyone try using one of these yet?

I have one of these old boxes lighting around, if you dont know what i'm taking about, i'll have to take a picture.

I have tried this sort of by using the ground glass focusing plate from a hand cranked 16mm projector. Twas alittle too grainy but they all have different grains so you should still try.
