Anyone using Pentax Auto 110 lenses?

[Moses Chisel]

I did a search but the engine says 110 is too common a word for the search.

My question is about using Pentax Auto 110 lenses on the GH1.

There is someone listing an adapter on ebay #320455375295


The 110 lenses are all fixed aperture but are fast at 2.8

Four primes 18, 24 50 & 70mm
One Zoom 20-40mm
and a PanFocus 18mm

The nice thing is they are cheap - you get the whole set preowned about $100 and they turn up on ebay regularly.


If you are using these lenses I would like to see some clips if you can point me to them

First time I've seen it mentioned. Sounds very cool and given that the Kodak 110 cartridge used in those cameras had a negative size of 13 mm × 17 mm it should have a image circle matching perfectly the m4/3 sensors.

I digged around and found a dpreview post with some stills

sharpness seems adequate

would still like to see some video though


also found the manual for the lenses

these tiny lenses are quite sophisticated

Optically they will likely be more than enough for the video encoding - the problem for video will be doing accurate focus pulling on such a small lens, unless you are a leprechaun, and attaching any kind of gears for a follow focus looks really difficult.

Haven't even heard of these Auto 110 lenses before, but looks fun. I otherwise use a Pentax adaptor. What mount are these, not Pentax K obviously!

Looking a little closer, I'm not sure how practical these would be for video. If you're in lighting where you need 2.8, it's be fine...but as soon as you have any substantial amount of light...unless you're going to find a massive step-up ring or invest in a miniature set of ND filters (Does such a thing even exist)?

Still might be kind of fun though, I must admit.
