Q: 1. Do any of the auto functions work like aperture stop down, or is that even needed with the GFX100S body?

A: Using this adapter would require the lens to operate manually.

Q: 2. I have an older Pentax 400/4 lens with a male flange and I need an adapter that will slip into that flange which is rotatable to lock that lens adapter onto the that lens. The other needs to fit Canon EOS. Are this available? I can't find any reference to this adapter on the Fotoidox pages. I do have same adapter to Nikon but need same to fit Canon. Thanks,James

A: I'm sorry but I have no knowledge relating to this particular question.

Q: 3. Bought this adapter totally fine with running everything on manual... unfortunately shutter will not fire. Are there maybe specific settings I'm not set to for this? Working with the Fuji GFX100s and Pentax 67 2.8

A: You should turn on "Shoot without lens" in the camera menu.

Q: 4. I have a cheap version of this adaptor - 30 bucks off ebay - while it all works and fits well - my Pentax 67 lenses are very prone to flare - FYI this adaptor is attached to a metabones - then to a Sony A7S2 / R2 . I doubt weather my metabones is causing the issue here. I suspect its the interior of the cheap adaptor - does anyone here that owns one of these Fotodiox know if the interior is a super matt finish similar to the metabones ? Or is it a shiny painted black ???

A: It's very, very matte, and very grainy like a course powder was coated on the inside.

Q: 5. will it fit the leica 007?

A: Yes, it is compatible with the 007.

Q: 6. will this work with a pentax ka mount?

A: Yes, it should work, but I have not personally tested it. As far as I know, the KA lenses are very similar to the K, but have autofocus features whereas the K lenses are manual only.Hope this helps!

Q: 7. 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: 8. Is this where Ricoh lenses would fit in too?

A: I really don't know.

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. 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.
