Related Questions and Answers

Q: 1. Will this work with the NEX 7?

A: Yes, this will be compatible with the NEX7.

Q: 2. Is there any way to adjust this so I can achieve infinity focus?

A: Unfortunately this cannot be adjusted in any way and is designed to mount at a specific distance from the Sony camera sensor. There may be alternative accessories you could add to it for infinity focus. We may have several options, available from multiple companies, depending upon your needs and their unique features. Please contact our Sales team via chat, email, phone, or visit our NYC SuperStore for additional information.

Q: 3. Understanding that it says this adapter works with EF lenses, does anyone know if it will also work with EF-S lenses?

A: No. Some 3rd party lenses for Canon APSC format will work, but NOT actual Canon EF-S lenses. Canon equips the EF-S lenses with protruding structure that obstructs them from fitting the non-S EF mount. 3rd party lenses hafta be built to be either Nikon or Canon from the same basic lens, so they aren't built with protruding structure.

Q: 4. Will this adapter work on the original Sony a7iii?

A: a7iii is full frame camera- meaning that you will only be able to use this adapter in crop mode or video mode. This focal reducer is meant to adapt a full frame lens to APS-C sensor bodies to give maximum coverage. What you want is a passive adapter (no inner optics) for your a7iii so that you dont get heavy vignetting.

Q: 5. Can it work on FS700?

A: I haven't done extensive tests on picture quality, but I can say that it generally works very well on the FS700. As advertised it increases the aperture and field of view, and reduces the depth of field. I've used it with a Canon 24-105 L, Tokina 11-16 and Tamron 70-200 and it is able to control the aperture of all these lenses. Don't know about autofocus because I don't use it. I'm very happy with this adaptor, especially for the price. Worth it.

Q: 6. Just to be really clear, this will allow me to use an RF mount lens on an EF mount body? It says compatible with Jupiter lenses, but they are PL or EF, not RF.

A: The Sirui Jupiter EF-RF Adapter for Canon RF Lenses to Canon EF Cameras is only compatible with Sirui Jupiter cine lenses.

Q: 7. Will this work for the Tamron 70-200mm F2.8 DI VC USD (EF mount) on the Sony A6000?

A: As long as it is the EF Mount.

Q: 8. Will this work with the sigma 8mm f/3.5 EX DG Circular Fisheye len?

A: Yes. The auto focus hunts for a while, but auto focus does work.

Q: 9. Will this adapter work on a Sony a6500? ( the pdf chart goes up to a6300).Is there an updated chart? Thanks!

A: Yes, this adapter works with the Sony a6500.

Q: 10. Will this work with the Sony FS5?

A: Yes, I'm still looking for a lens that the autofocus will work with though.
