Well, actually both, for fun and pleasure and finally, I have a couple of km 30+ year 8mm film that need to be transfered so I can store the actual film in a safe enviroment, probably N2 atmosphere at -30 degC. > > Why not use a consumer digital camera and project the film > using a relay lens to get appropriate image size?

A lowly 3 MP camera today. Well, you can project a 8mm film quite large (A0 size or so) without getting any grain, so I thought that getting a resolution so it can be viewed on 42 in HDTV or similar is the lowest resolution I can accept. > > With modern optics you can get as good a result as your > 'direct projection' > method.
