Pentax Q adapters?

Just got an Q7 Kit and need some advise on third party adapters for it to use the following lens:
  • Pentax 110
  • K-Mount
  • M42
I looked in the reviews and did not see anything there.

Thanks for your input / help.

I asked about the K-Mount adapter, and got wonderful, concise info here:

Plenty of discussion in the Q subforum

Pentax Q - PentaxForums.com

I have a cheap K-mount adapter and am replacing it with the Pentax Adapter Q. No need for an M42 adapter because I can use Pentax Adapter K with it.

Get the Pentax adapter IMO:

For 110 there are commercially available 110-Q adapters available.
Check the sticky thread at the top of the Q forum for examples of adapted lenses in the reference thread.
There is advice on how users tweak for best results.

No need for an M42 adapter because I can use Pentax Adapter K with it.
Plus an M42-to-K adapter which is no problem.

However, a M42 - Q adapter plus some very economical M42 extension rings is a very inexpensive way to explore close-up/macro with M42 lenses. The same could be said for the PK - Q adapter however the extension rings are much bulkier.

E.g., a 20+30mm ring stack will produce a nominal 1:1 macro image with a 50-55mm lens on either the Q or Q7. FOV is on the order of 5-8mm wide from MFD to infinity focus. A single 20mm ring provides a nominal 1:2 ratio and an FOV of appx 10-20mm wide.


[Note: A clamp-type tripod foot around the rings is a good idea to take the weight of the lens off the mount.]
