From: Cheesehead on 21 Jul 2010 12:24 A 4x5 film holder that has a slot for a strip of 35mm film in the center. Might make not only for some great 5" neg panoramas, but also provide a way to use some films not ordinarily available to 4x5 (albeit in a reduced form factor). I'm thinking of making one from an old holder. My Caltar HR 210/5.6 turns out to be quite sharp. Shot on certain 35mm films it might be quite nice. Just a thought. Enjoy.

But I doubt if anyone manufactured such a thing. (But of course it's possible.) If a guy wanted to experiment with 35mm in a 4x5 camera, a guy could just cobble up a homemade holder by taping some cardboard strips into a holder to hold a piece of 35mm film. I'd use two thin overlapping strips on each side, with the top one projecting out a little bit to hold the film in. You should be able to slide the film in from the edge of the holder through the dark slide slot. (That'll probably take some practice in the dark.) Of course, if you're going to do this, you might also want to think about using a wide-angle lens if you really want a panorama and not just a thin strip of a picture. -- The fashion in killing has an insouciant, flirty style this spring, with the flaunting of well-defined muscle, wrapped in flags. - Comment from an article on Antiwar.com (http://antiwar.com)

Except that the slide won't clear if you put the guides such that you can get the film _under_ them, and the film won't stay flat if you don't, because 120 film is much, much more flexible than either 4x5 or 35mm film. The problem you'd have with 35mm film is that it is curved across the narrow dimension and would practically require a vacuum back to stay flat in a 4x5 holder without a special slide and back that worked much like the film gate and pressure plate in a real 35mm camera. 35mm in 4x5 is a real pain. 120 is not as hard but you'll do a lot better to use a factory made holder. Otherwise, in both cases, sure, you'll get images, but parts of the film will be so far off the plane of sharp focus that if you can convince yourself the results are sharp, you're a much better liar than I am. -- Thor Lancelot Simon tls(a)rek.tjls.com "All of my opinions are consistent, but I cannot present them all at once." -Jean-Jacques Rousseau, On The Social Contract

Are you sure about that? I'm looking at a 4x5 holder (old Graflex), and there is a good 1/8" between the slide and the back of the holder where the guides would go. Looks like plenty of room for some paper guides. They only need to be about 3-4 times the thickness of the film total. Can't guarantee how flat the film would stay, of course, but might be worth a try. -- The fashion in killing has an insouciant, flirty style this spring, with the flaunting of well-defined muscle, wrapped in flags. - Comment from an article on Antiwar.com (http://antiwar.com) |
