Fits Select T-Mount T/T-2 Screw Mounts    Focus to Infinity or Beyond    All-Metal Design    Anodized Aluminum Construction

Pentax K (PK) Mount SLR Cameras
Popular models include:
K-7, K-x, K-r, K-5, K-01, K-30, K-5II, K-5IIs, K-500, K-50, K-3, K-S1

This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.

Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.

If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.

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

A: Typically the lens cannot be removed.

Q: 3. 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

Q: 4. 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: 5. Hi, just wondering if this adaptor would work on my Nikon d5500 body? Thanks

A: Lens adapter did not work for my camera. I have Nikon D3200. although the lenses fit to the camera my camera did not recognize that there was actually a lens attached. Having the lens adapter did not work even in manual mode. So looking forward to using my Pentax lens again but I just can't make my camera recognize the lens so it can't focus.

Q: 6. What is the function of the movable silver ring on the adapter?

A: This FotodioX Pentax K Lens to Nikon Z-Mount Camera Pro Lens Adapter is designed for lenses that do not have a manual aperture control ring, such as the newer Pentax K AF lenses. This adapter has an aperture control dial built into it which will allow you to open and close the lens manually. The silver ring is for controlling the aperture.

Q: 7. Does it also work with Pentax PK mount lenses?

A: Wikipedia says PK is an abbreviation for Pentax K so it should.

Q: 8. does this adapter come with caps to close it when not in use?
