Topic: Can the lens from a 110 camera be used in M4/3 ? Like lens in a cap ?

Hello from Maine USA smile

Hey I really enjoy Rokkor lenses - I have a 110 camera from 1977 with a 26mm f/3.5 Rokkor lens in it, this one :

I don't know the flange distance for 110 cameras, but I wonder if lenses from those cameras can be used as lens in cap on Micro 4/3 ?

I'm interested in up-cycling the lenses from old cameras that could be thrown away. While that camera may only be worth a few dollars today, I'm sure Minolta engineers worked hard to design it. Especially the lens smile I bet it's a good quality lens but I wonder how I can use it ?

Thanks,
Craig

I don't think 110 cameras have a standard flange distance, because few have had interchangeable lenses anyway (and those that had them were closed systems).

That said, I suppose there has to be at least one centimeter between the lens and film, if only because of the shape of 110 film cartridges. That's much less than M4/3 requires, so you'll need to design a cap that goes deep in the body to adapt this lens.
Now, you'll also need a way to change the aperture (if it's possible on the original camera). Good luck with that. hmm

Why not open the camera and measure it?

I've read that a Pentax 110 bayonet mount lenses(zoom, 18,24,50 and 70mm focal lengths) with appropriate adapters will work on most mirror less cameras with varying crop factors. The caveat is that the lens can only be used wide open. This is not a big problem as Minox 8x11 cameras fired at 15mm FL with constant open aperture at all times, exposures recorded by manually varying shutter speeds. Not owning a mirrorless body, I cannot verify the performance.

This is sort of a related issue but might have some application here. Years ago, I got tired of having an old D-mount 8mm movie lens rolling around in my misc stuff drawer, so I decided to do something about it.  Recalling that reverse-mounting a lens gave one a much magnified view of the subject matter, and recalling that the shorter the focal length the greater the magnification, I figured, hey, why not? So I took this D-mount lens -- like a 1/2" Wollensak if memory serves, so about 13mm or so -- and I glued it to a 49mm lens cap. Well, first, I drilled a 1/2" hole in the center of the cap, so light would pass through. Heh. Then I mounted the reversed lens/cap to my Tamron 90mm f/2.5  macro and took it outside to see if I could find interesting things to take very close-up pics with. The magnification was simply startling. I don't really know what it was, although if I would have taken a pic of a ruler, I probably could have figured it out. But suffice it to say that this little setup was the most highly magnified macro setup I owned. And to top it all off, the images were actually pretty good. A decent amount of sharpness and detail.

I think I might have a few pics on my website. I'll go look.  Okay, here's what the Wollensak lens looked like glued to the 49mm cap:

Well as it turned out, since the depth of field was razor thin, even when stopping down the Wollensak to f/8 or so, I decided on a flat subject. I chose a Lexmark printer box. Here's a pic of the box:

Okay, so you see the wavy Windows logo?  Well there was a copyright statement under it, stating among other things that it was good for Windows XP. Tiny text, as the image shows.

Here's a closer look at the text -- legible in this shot, but this was a close-up photo:

And here's the shot taken with the reverse-mounted Wollensak:

The image was full-screen with no vignetting, surprisingly enough. But it was shot using an APS-C EOS DSLR. Center sharpness is very good, but edge sharpness is just ok. Still, it's amazing what you can do with a little lens when reverse mounting it, isn't it?  And why wouldn't a 110 lens be up to a similar task? Eh?  It would at least be a bit of fun with your macro lens.  Oh, yeah, I haven't tried this Wollensak with anything but my Tamron macro because I figured I'd need the extension the lens provided to get an image properly in focus. But this might not necessarily be the case.  Something to experiment with, I suppose.

Reverse-mounting a lens makes the flange distance largely redundant. You probably won't be able to use it for normal photography but, on extension, you can get some excellent macro. My main high magnification macro lens is a Schneider 40mm HM enlarger lens, reversed.
