Like Ole, I sometimes use an enlarging lens on 35mm camera bellows via adaptors. There are shortcomings: a longer than normal enlarging lens is necessary to permit focusing on distant subjects, the smallest aperture sometimes doesn't give adequate DOF for macro photograhy, and one must calculate the effective f/number. I've been happy with the images.
When I remove the front adaptor ring from my Novoflex
bellows, the M39 Female threads fit the threads on
my EL-Nikkor 50mm f/4 Enlarging lens. Use it on a Nikon F2AS
for extreme close up, flat field photography. Stamps,
coins, and the like. Works fine, except bellows won't
compress enough to get to infinity, which is why I
have a 50mm f/1.4 for normal work.
Well, I shot a roll through the camera last weekend, and the upcoming weekend I'll be printing from it. So far the negs look good, but since it's 35mm it's difficult to tell without a decent lupe. They appear to have normal densities, good sharpness, even contrast control looks well managed.
Thanks again for all of the enlightening contributions. I'll be sure to post my results here some time next weekend.
If you can find a camera that was in one of those early 35mm film recorders used to turn out powerpoint slides in the late 80's, early 90's, then more than not, the recording mechanism is a motor drive 35mm with a custom, fixed focus enlarger lens mount set at 1:1 (or whatever the target/frame ratio was).
I have one of those mounts around here, but can't remember off hand what mount is for; Chinon maybe?
So I finally printed some negs taken with the Schneider Componar 105mm... It came out surprisingly well. I think I'll keep using it as a camera lens. I have to learn to use it in a portrait setting first, but it really works!
Nice density in the negs, wonderful sharpness, but most of all I was shocked by the contrast control. Attached below is a scan of a print.
Lens: Schneider Componar 105mm enlarger lens. On DIY barrel and focusing ring. Mounted to a Pentax KX body with the K-mount.
Film: Fuji Neopan 1600 @ 640, souped in Pyrocat-MC using semistand technique.
Printed: on Ilford MGIV in Ansco 130 diluted 1+1
I'm VERY surprised by the results.

In your opinion, what are the differences optically between an enlarging lens and a camera lens? Why would one design be used for one purpose over another?
An 80mm enlarger lens is designed for medium format, and so when mounted on a 35mm camera will have a much larger image circle than a 35mm lens. It is possible to use a piece of black rubber (e.g. from a bathroom plunger) with a hollowed out body cap to create a flexible mount for such a lens - hence giving you a cheap tilt and shift lens. This is basically the idea behind a lensbaby, but at a fraction of the cost - enlarger lenses are going for peanuts on ebay
