Impressions & Notes
- It is a fun experience as the Pentax Auto 110 24mm f/2.8 is the smallest among the 110 series of lens. Its filter size is 25.5mm.
- Corner vignette and softness is seen but not too bad especially if you shoot in b&w. It has a naturally looking vignette in the corners.
- Lens are shot wide open as the Pentax Auto 110 to NEX adapter don't have diaphragm control and neither do the Auto 110 lens has any iris. The leaf shutter stays in the Pentax Auto 110 body.
- Shots are shot wide open in f/2.8 without option to control the aperture and it may not be desirable if one want to get the best image quality of one's lenses.
- The Pentax Auto 110 to NEX adapter is the thinnest adapter that I have seen and if you are after the miniature setup, the Pentax Auto 110 is the smallest setup that one can consider.
- The limitation of Pentax Auto 110 lenses when used in NEX 5N lie in the light loss around the corners due to partial coverage of the APS-C sensor and absence of mechanism to stop down the lens aperture.

Hi! I was wondering of you cropped your images? If you did crop because of the loss in the corner, how much did you crop? Thanks!!
I did not crop any of my test pictures. The picture link to my flickr photo set and you can examine the un-cropped pictures. The vignette in corners are harder to show up in b&w and when they do, it is not severe. But I do run into them occasionally with the 24mm
Whats the name of the ADAPTER ?
I have the Pentax Auto 110 24mm Objective and the Sony NEX 5NY ? I need an adapter for it!

You can take a look at this link
RainbowImaging PTX 110 to NEX adapter.
In ebay, look for PTX (or Pentax) 110 to NEX adapter.
A caution though: I have tried two different adapters from Rainbow Imaging and another one from ebay jinfiance with RJ name, both are loose in mounting the 110 lenses. The lenses move a bit when you turn focusing ring to focus -- your mileage may vary.
