The Adapter for Contax G Lenses to Pentax Q Mount Mirrorless Cameras from FotodioX allows a Contax G lens to attach to a Pentax Q-series camera body. Adapting a larger format lens to a smaller format sensor provides optical as well as practical advantages. The smaller image field helps minimize the effects of lens distortion and aberration by using the center or "sweet spot" of the larger lens' image circle, thus providing edge-to-edge sharpness.

Although the lens will fit physically, automatic diaphragm, auto-focusing, or other electronic functions will not operate correctly while using this adapter. Manual or aperture priority mode must be used when this adapter is attached. Its all-metal design and polished surface provide smooth mounting and long lasting performance.

Related Questions and Answers

Q: 1. Description mentions iris control on the adapter, but there is no such lever or control from the photos. Can you confirm if it is possible?

A: Yes there is iris control with this adapter.

Q: 2. Can this adapter fit Film Rangefinder camera of VM mount

A: This adapter works well with Leica M 240 camera because the digital display can be used to frame and focus the image. Although film type M cameras have the same flange focal distance as the M 240 and will work just as well with this adpter, but you will have to guess the object distance and the framing. The distance is easy enough to guess (using a small aperture helps) but for framing you may want to imrovise a flash shoe viewfinder. Good luck.

Q: 5. I’ve read Contax G system’s AF would always return the focus to it starting position. Is this the case with this adapter? I mean, is there a spring in the lens that returns the focus back or once this adapter is used the lens becomes a manual lens like Leica for example? Also, does it have a hard stop at infinity or one can focus past it?

A: The lens adapter is a manual one. It does not transfer any electronics of the lens. The lens will not have autofocus and like the adapter it will be manual only.

Q: 8. Will this work with a Pentax Q-S1? I am interested in utilizing vintage Pentax K lens with my little digital Q-S1.

A: I have a Q10 and while I've had this FotodioX devise a long time I'd never tried it on the Q10 (The Q10 is the camera that lives in the car and see very little use). And low and behold it doesn't fit properly. So I'd set up purchase rule with B & H if it doesn't work! As I should have. Cheers ReedE
