Do Auto 110 lenses fit a K-x/K-7?

I can't seem to find what mount the Auto 110 camera uses?

It uses Pentax 110 mount

Not compatible with any other mount.

The lenses are too small for APS-C sensor anyway.

The Auto 110 slr had its own mount. It is sort of like a mini-k but with 2 bayonet flanges instead of 3. These lenses were designed to cover 110 film which is roughly 16mm which ironically is in the neighborhood of the 4/3 sensors. Some people have made adapters to use the lenses on those formats. The aperture is integrated into the 110 body.

They might fit INSIDE your camera though, those are the tinyest lenses that I have ever seen.

The 70mm is the size of some of the LTD lenses.

Really?

I've seen some examples of Auto 110 lenses mounted on the E-P1 on my forum, and it seems like they would fit inside of the camera because they're so small. Am I thinking of a different type of lens?

I don't have the 70mm 110 lens here with me, but I think it is larger than most DA Ltd. lenses, except for the 35mm macro.

The 70mm has 49mm filter thread (same as Ltd. lenses), and probably 1.5" long (tapering toward the rear of the lens, however).

That's it in my Avatar. Now if I change my avatar, people's head will explode. I need to line up my LTD lenses and the 70mm and make a comparison shot.

Here are the DA 70mm Ltd., the 110 70mm and the Pentax 110 body. It shows how small the DA 70mm is:

Soldbear did a comparison of the DA 70mm ltd. Here is a comparison of the FA 77mm ltd and the Auto 110 70mm lens . . .



Here is an example of the 2 flange bayonet mount found on the 110 lenses. Not the size of the mount cap compared to the K mount cap on the 77mm ltd . . .

Some folks use them on a m4/3 camera with an adapter. However, there's an issue of some sort with aperture. Like the only option is shooting wide open or something.

Pentax 110 lenses on adaptor [Page 1]: Micro Four Thirds Talk Forum: Digital Photography Review

It really seems that the m4/3 cameras with their short registration length make all kinds of interesting lenses usable to some extent.

in my view ...: Pentax 110 adapted lenses on micro4/3

The actual aperture system is in the 110 camera body. The lenses are rated at a maximum aperture of f2.8.

Wow, I was really hoping that some kind of mount adapter existed so that I could possibly use one of these cool and small lenses. A couple weeks ago I stopped by the Air Force Museum in Dayton and they actually had a 110 on display in the spy gadgets section, boy was that cool to see.
