Bosse Blomqvist pulled the lens off a Lex35 and put it on a 4×5 camera with a medium format 9x12cm back. Above is the somewhat surprising result: the coverage is far bigger than I’d have expected!

Had to check out how the magnificient Lex 35 would behave as a large format camera, or at least how the lens would perform when mounted on a view cam and using it to shoot a 9x12cm negative…
The Lex35/Vivitar T100 is a crappy, hackable, cheap, plastic camera. Above is Eben Ostby‘s result from flipping and spacing the lens. He writes:
I don’t have pictures to show what I did, but if you look at my photostream, you’ll see a few "addled" photos that were done with a Lex 35 with a flipped lens. Here’s what I did:
Took apart the Lex35 [Eben’s instructions, with photos, are here].
Took the lens "board" off by removing its two screws. On the back of the lensboard, there’s a plastic ring that holds the lens in place, and which can be popped off by prying it gently with a screwdriver or such.
The lens comes out and can be reversed and placed in the front part of the lens-holder – in the stepped rings that are visible from the front. I used a thick washer to hold it in place, but you can improvise something else… tinfoil, glue, putty… I dunno. With the lens pushed as far back as I could get it to go, it the camera "focuses" (if that’s really the word) from about 2 feet to 30 feet. Sort of.
I also tried flipping the lens around but putting it back in the back part of the lensboard. If you do this, you’ll need to shim the lensboard away from the body of the camera, and use longer screws (such as the ones that hold the body of the camera together). And the focus is worse.
I’ve gotta say, I’m thrilled at having a screwed up Lex35 like this. It just made my week.
You can pick up a Vivitar 100 (same as the Lex35 except it has a tripod mount) for US $1.95 from American Science & Surplus.

The Lex 35/T100’s shutter cocking mechanism is coupled to its film advance, so reliable multiple exposures are out on a stock model. If you’ve got a screwdriver, a metal coat hanger, a pair of pliers, and some tape, this is not a problem. This will show you how to add a key that will cock the shutter without touching the film advance and allow you to shoot multiple exposures with impunity as well as how to block the shutter from closing, allowing you to keep it open as long as you want…
