The Pro Lens Mount Adapter for Rolleiflex 6000-Mount Lens to Pentax K-Mount Camera from FotodioX allows a Rolleiflex 6000-mount lens to be used with a Pentax K-mount camera. It is designed to support focusing to infinity, and is constructed from brass and an aluminum alloy to provide a durable, yet lightweight camera-to-lens connection.

This adapter does not support electronic communication between an attached camera and lens. To control the amount of light that enters a Pentax K-mount camera when using this adapter and a Rolleiflex 6000-mount lens, an iris is built into the Pro Lens Mount Adapter for Rolleiflex 6000-Mount Lens to Pentax K-Mount Camera. This iris allows for approximate adjustments of brightness as well as depth of field along with a manual Pentax K-mount camera or an electronic Pentax K-mount camera set to manual mode.

To help prevent stress on the camera mount if the supported camera and lens combination is to be placed on a tripod, the Pro Lens Mount Adapter for Rolleiflex 6000-Mount Lens to Pentax K-Mount Camera includes a detachable tripod foot that features 1/4"-20 threads.

Q: 6. 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.

Q: 7. 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: 8. 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: 9. would the medium format pentax 6x7 lenses fit this adapter and work on nikon digital (d610)and 35mm(nikon f100) film bodies?

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?

A: It can be used in FF mode, assuming the Pentax lens is a FF lens.
