The Adapter for Leica R Mount Lenses to Pentax Q Mount Mirrorless Cameras from FotodioX allows a Leica R 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 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: 2. so,,want to have an adapter for my sony a 57 lens to fit pentax kaf2...body???

A: I have Nikon manual focus and zeiss manual focus lenses adapted to my Pentax K3, KS2, and K01. You will likely lose autofocus capability. My cameras automatically go to AV exposure mode. The camera exposes properly for the f stop I set the lens to. The adapters I have add a glass element and I find stopping the lens down two or three stops from wide open helps image quality. Sharpness is fine, but I notice a drop in contrast. But I can control that in post processing. For me it was a reasonable investment to add several lenses to my arsenal.

A: I am using the adapter with a Vivitar 135 mm lenses on a Nikon D700. The quality is ok but I have not found it exceptional. I would need more experience to give a definite opinion one way or another. I just got the adapter and have not taken a lot of photos yet.

Q: 8. How do I remove the 1.4 lens from the Fotodiox Pro?

A: Typically the lens cannot be removed.

Q: 9. What would I need to mount Pentax K lenses to the Sony A6300 ?

A: As the Sony Alpha a6300 Mirrorless Digital Camera uses the smaller Sony E-mount lens mount, it is not compatible for use with the FotodioX Pro Lens Mount Adapter for Pentax K Lens to Sony A Mount Camera listed above. The options we carry that would allow you to connect a Pentax K-mount lens onto the Sony E-mount lens mount would be either the Novoflex Adapter for Pentax K Lens to Sony NEX Camera, B&H # NOAPKSNEX, the Voigtlander Adapter for Pentax K Lens to Sony E Mount Camera, B&H # VOEAK, or the Dot Line NEX Adapter for Pentax K Lenses, B&H # DODL0809.

Q: 10. If using on an A7 ie full frame camera, will you have to put the camera in crop / super 35 mode? Or can the full frame be used?
