The Adapter for Nikon/Contax RF S-series Mount Lenses to Pentax Q Mount Mirrorless Cameras from FotodioX allows a Nikon/Contax RF S-series Mount 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. Can this adapter be used for an external bayonet mount lens like the Jupiter 11 135 f4 ? (http://fedka.com/catalog/product_info.php?products_id=88)

A: Unfortunately, the Jupiter-11 135mm f/4 won't work with this adapter, since the Contax rangefinders have a different mount than the Contax/Yashica lenses, as the Contax/Yashica lenses have an SLR mount. At the current time, there are not any adapters made for the Contax Rangefinder mount to any other current camera mount.

Q: 2. Will this adapt a canon RF lens (800mm f11) to a Nikon Z Mount(Z9) camera? If not, is there one available you can recommend?

Q: 4. Does the aperture priority mode actually work, and is there a difference of focus like on a DSLR if you use a lens it’ll appear in focus but when you take the picture it won’t be because of the different distance to the sensor
