Related Questions and Answers

Q: 1. Is the 645 format a standard like MFT? Meaning, is the Pentax 645 the same mount as a Mamiya 645? Will this adapter work with Mamiya or Schneider-Kreuznach lenses that use the Mamiya 645 mount on Fujifilm GFX cameras? TIA.

A: The Pentax 645 and Mamiya 645 offer the same film format, but with different mounts for their respective lenses. This adapter accepts Pentax 645 lenses that originally worked on the Pentax 645/645AF medium format film bodies or 645Z medium format digital body.

Q: 2. 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: 3. How do you change the f-stop when using this adaptor?

A: When using the Vello Pentax K Lens to Fujifilm X-Mount Camera Lens Adapter, one is not able to change f stops, unless the Pentax lens features manual f stop control. If the lens does not have manual f stops, the lens will step down to the smallest f stop.

Q: 4. What's the crop factor from Pentax67 to X fuji mount?

A: The crop factor on an X mount Fuji is 1.5x.

Q: 5. Is that a tripod mount on the adapter?

A: Yes. The FotodioX Pro Mount Adapter for Pentax 645 Lens to Fujifilm G-Mount Camera has a tripod foot for added support when adapting the lens.

Q: 6. Does this change the focal length of the lens?

A: While the adapter itself has no optics that would directly affect the angle-of-view of the lens (meaning no magnification or cropping from the adapter), the difference in formats between 6x7 and Fuji G formats would introduce a crop factor, essentially narrowing the field of view of whatever lens you adapt onto the GFX-series of cameras.

Q: 7. 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: 8. Can I use this on my Pentax k-70? Thank you!

A: Yes

Q: 9. Does this allow using a "Pentax smc FA 645 200mm f/4 IF Lens" on GFX body with AF?

A: FotodioX Pentax 645 Lens to FUJIFILM G-Mount GFX DLX Stretch Adapter doesn't support autofocus.

Q: 10. does this adapter come with caps to close it when not in use?

A: I'm sorry, this adapter does not come with caps.

[3 x 3 x 1.5"] Really nice adapter. Works exactly as you would hope! 5

[3 x 3 x 1.5"] I purchases this to be able to use older 645 Pentax lenses on a Fujifilm GFX body. It works just fine. I like the tripod quick release mount and the aperture adjustment one the mount. 5

[Metal, Brass] Coming from a machining background, I found this adapter to be well made and functional in adapting a T Screw mount device to my Pentax K-mount cameras. Definitely recommend it. Three tiny screws allow it to be 'clocked' and locked on T-mount threads. 5

[FUJIFILM X] Well, mine worked. It is useful for attaching a Pentax 50mm 1.4 SMC to the Q-S1 as well as a Tamron 500mm mirror lens with a Pentax Adaptall K mount adapter on it. It's just a piece of machined aluminum with a steel plate attached at the K end. 5

[Metal, Brass] This T-mount will work on Sigma SA mount and is ideal for macro work T-mount extension tubes or T-Mount bellows. The adapter is a true T-mount (42mm) with 0.75 thread pitch. This adapter will not damage the gold contacts of the Sigma SD Quattro mount for transmitting data from lens to body. When mounted the adapter is still about 1 millimeter away from the contacts. Since it does not have any gold contacts it works only in manual mode. It is simple, well-made and excellently machined. 5

[3 x 3 x 1.5"] I wanted a way to adapt all of my favorite Pentax lenses to my favorite Fuji sensor, and FotodioX gave that to me. It's simple, straightforward, and well-built. I've been using it for a few weeks and, aside from getting used to the slightly different focal lengths from a change in sensor, it's been a breeze. As much as I love Fuji glass, being able to use my vintage lenses has brought so much character to the massive photos the Fuji GFX delivers. 5

[Metal, Brass] Typically i shoot manual and although i love fuji lenses, their manual feel could be a bit better. With this mount i can use my vintage manual focus lens with ease. Its great! Also, the mount adapter has its own aperture control. would definitely recommend this to anyone wanting to try out their vintage lenses on a digital camera :D 5
