The Pro Lens Mount Adapter Kit for Rolleiflex SL66-Series Mount Lens to Fujifilm G-Mount Camera from FotodioX includes two adapters, one of which allows a Rolleiflex SL66-series mount lens to be used with a Canon EF or EF-S mount camera, while the other adapter allows a Canon EF or EF-S mount lens to be used on a Fujifilm G-mount camera. When combined, the two adapters allow a Rolleiflex SL66-series mount lens to be used with a Fujifilm G-mount camera.

Together, as well as individually, these adapters are designed to support focusing to infinity. The FotodioX Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera and the FotodioX Pro Lens Mount Adapter for Canon EF or EF-S Mount Lens to Fujifilm G-Mount Camera are constructed with brass. Both adapters also feature stainless-steel lens mounting rings to provide a durable, yet lightweight camera-to-lens or camera-to-adapter connection.

For focus control when using this adapter kit on a Fujifilm G-mount camera, or the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera on a Canon EF or EF-S mount camera, the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera features a built-in helicoid that extends and retracts a compatible lens in a manner similar to a Rolleiflex SL66-series camera's focusing rack. Similar to a Rolleiflex SL66-series camera's lens mounting ring, the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera offers the ability to mount a compatible lens in reverse. By utilizing this feature, the focal length of the attached lens relative to the camera being used is shortened, which can then provide a macro effect.

When removed from a compatible Canon camera, the aperture diaphragm on a Canon EF or EF-S mount lens is designed to open to its widest setting. A Canon EF or EF-S mount lens may be effectively used with its aperture diaphragm fully open along with the Pro Lens Mount Adapter for Canon EF or EF-S Mount Lens to Fujifilm G-Mount Camera. Otherwise, an aperture value on a Canon EF or EF-S mount lens may be set by first placing the lens on a Canon EOS camera and then pressing the camera's depth of field preview button while removing the lens prior to placing it on the adapter.

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 SL66-Series Mount Lens to Canon EF or EF-S Mount Camera includes a detachable tripod foot that features 1/4"-20 threads.

Q: 1. Hi, totally new to astrophotography. I want to connect my Fuji X-Pro2 to an old Tele-Vue Pronto telescope using (I think) this: "Tele Vue SLR Prime Focus Camera Adapter for 2" Focusers." Would the FotodioX T2A-FXRF be the missing "link" to what I need to interface everything? Thank you!

A: The items you listed and the FotodioX Lens Mount Astro Adapter Compatible with T-Mount Telescopes to Fuji X Mirrorless Camera BH #FOT2AFXRF • MFR #T2A-FXRF would be the appropriate adapter.

Q: 2. On my test with 3 Hasselblad lenes. There seems to be an issue of back focus. Is that possible?

A: The FotodioX Hasselblad V Lens to FUJIFILM G-Mount Camera Pro Lens Mount Adapter could cause back focus issues.

Q: 3. Help! I am trying to use this adaptor with my Nikon AF-S NIKKOR 70-200mm f/2.8E FL ED VR on my new GFX 100s. everything mounts up but I have NO aperture control. it seems to default to wode open or fully stopped down. I cannot control the aperture at all. this is useless in this state. Is there any resolution? Thanks..

A: When your Nikkor lens is wide open, the aperture control on this Fotodiox NIKG-GFX-PRO would be utilized.

Q: 4. How much of Fujifilm GFX-50S sensor's area is utilized by Leica M Lenses attached with this mount?

A: The Leica M lenses are mainly full frame (35mm) compatible so there would be a crop factor of 0.79x applied to those lenses using them on the Fuji GFX-50S.

Q: 5. I have used this with a 80mm c, 50mm distagon c chrome and 250mm c chrome. All seem to have back focus. Is that possible?

A: The FotodioX Hasselblad V Lens to FUJIFILM G-Mount Camera Pro Lens Mount Adapter is a manual adapter. Meaning you focus manually and has no autofocus ability. It does not make sense with a back focus issue.

Q: 6. Has anyone used a Hasselblad 500 mm lens with the Fuji GFX and how was the quality?

A: The lens adapter has no optics. So it does not take away from the lens’s optics.

Q: 7. I have a NiSi X-len. Is this X len and the Xpan lens the same size? I intent to mount to A fujifilm G mount camera body.

A: The size is not the important factor--the design of the mount is. Only Xpan lenses are compatible with this adapter.

Q: 8. Does it restrict image circle? Canon EF is not a digital MF lens mount. Does it cut off the 6x6 Bronica image circle?

A: The FotodioX Pro Lens Mount Adapter Kit for Bronica S-Mount Lens to Fujifilm G-Mount Camera does not restrict the image circle of a lens attached to it; however, an EF or EF-S lens would not have a big enough image circle to cover an area larger than full frame--both the Bronica and the Fujifilm G-mount sensors are larger than full frame.

Q: 9. What is the use for a Fuji X mount to Fuji X adapter?

A: This is a Fujica X-mount Lens to Fujifilm X-Mount Camera adapter. Fujica X-Mount if a vintage lens mount option which is no longer in production, however this adapter allows you to use those older lenses on the new Fujifilm X-Mount Cameras.

Q: 10. Does anyone know if this would allow me to use a vintage Hasselblad lens(from 1000F) that does not have leaf shutter on the GFX platform? Specifically, it's the Kodak Ektar 80mm, from back in the day when the Hasselblad had a focal plane shutter in the body, and not the leaf shutter in the lens. Thanks!

A: Yes, it will work without any issues.
