Showcase Pentax auto110 18mm/2.8

[Petrochemist]

A tiny little (27g) lens designed for Pentax's 110 film SLR system. Unfortunately lacking any aperture control as this was made in the camera.

NEX-6       0mm    f/1.0    1/2000s    ISO 100

Slight vignetting & corner softness seen here, as APSC is bigger than the lens was designed to cover. Here adapted via stacked MFT-NEX & PTX110-MFT adapters. A direct PTX110-NEX adapter is available & seems a bit more practical to use. Shame I can't find one with a iris in the adapter. - The 24mm version is smaller still at 12g & seems to cover APSC comfortably, better see about getting some examples with that!

Yes it seems if you've got a lens it's worth trying!
I've heard the coverage of the 24 & 50mm versions is better
