I was just looking around for some wide angle lenses and came across the Pentax 110 18mm 2.8 lens. It says that it was built in the late 1970's. Does anyone know anything more on the 110 lenses and if they would work on the DSLRs (ex. *ISTs in particular). I know that we can use older lenses as our cameras have the backwards compatibility but i just want to make sure.
Thanks

No, the 110 lenses won't work and can't be adapted.

No, 110 lenses don't work on the current batch of DSLRs.

I wonder why Pentax doesn't make a 110 digital. I'd buy one in a heartbeat.

Good to know that it will not fit the DSLRs. I searched for the answer and couldn't find it. Looks like a cool little lens though.

They can be made to fit the Panasonic Lumix G1 though.

The document linked looks very much like Panasonic marketing hype. I have yet to see a functional adapter to use Pentax 110 lenses on M43 cameras. The big issue with Pentax 110 lenses is that they have no diaphragm at all -- in the original Pentax 110 system, the iris was located in the lensmount attached to the camera body. It means that the adapter should have its own aperture ring and diaphragm, while remaining thin as a sheet of paper because of the short registration distance of these lenses. My conclusion is that if this adapter really exists, it allows only to use the lenses wide open, which is rather limitating.

Well, in fact I would love to try my cute 70mm F/2.8 on an EVIL camera, even if it's wide open only. It would make a nice 140mm equiv. portrait lens...

Cheers!

As others have noted, those lens are not compatible to current set of dSLR bodies.

I have few pictures of those tiny lens from my Auto 110 film camera. You get a picture of the size comparison.

As I recall, the lens don't have diaphragm, the mechanics are all in the body. And I have sold the entire set in Marketplace last year.

I think Fuji has stopped the production of 110 films and
those available films may become difficult to find



Complete set with 3 primes as I recall roughly
but there is a big crop factor in 35mm terms
18mm, 24mm, 50mm

A great article on Pentax Auto 110 from Rick Olsen is in this aritcle: World smallest camera by Rick Oleson

I had no idea how small they were compared to a DSLR. Now that is just tiny.

Hi,

I took a 24mm 2.8 110 lens and mounted it on a cheap body cap. I carry it when traveling light in case I want to do 1 to 1 macro. Can get very close and a nice full frame image. Have to shoot wide open because the 110 camera's aperture was part of the body not the lens. Still, it's cute to have a use for these old lenses and they sell cheaply on ebay. I don't really bother fiddling with the lens focus - I just position the camera to focus. No realistic way to make it infinity focus as the lens would have to be so close to the sensor that the mirror would smash into it. I also tried a 50mm 110 lens ( much larger and also only good for macro but the lens can be a bit further away from the subject - haven't used it enough to say if it's better than the 24mm.) Will attempt to attach a photo. These were taken on a K-m dlsr (so much lighter in my backpack than my 20D.)



Cheers,
Alan
