Related Questions and Answers

Q: 1. I have a Sony FS7 & FX9. I have a Fujinon 20-120, and Cooke Mini S4s. I understand there might be some vignetting which is fine. I wanted to know if you still get the speed boost stop with any PL lens. I don't understand how it could only open up full frame lenses? Thanks.

A: This will only work with Full-Frame PL Lens. In theory it should allow in more light on any lens, but it is not designed to work with lenses that do not cover a full frame sensor and we do not recommend it.

Q: 2. How well does the camera's autofocus system work with a Nikon F-mount lens using this adapter?

A: There is no AF function with this adapter.

Q: 3. Will it work with a tilt-shift, perspective correction lens?

A: Yes, this Metabones adapter will adapt over any Nikon F-Mount lenses to the Sony E-Mount body.

Q: 4. Investigating whether this would work with Sony FS5 II and Nikon 500mm f/4 lens or perhaps Nikon 200-400mm f/4. Would I be able to control aperture? Not worried about AF.

A: The Metabones Nikon F-Mount Lens to Sony E-Mount Camera Speed Booster ULTRA will mount onto the Nikon 500mm f/4, or the 200-400mm f/4, but one would not be able to receive electronic control of the lens aperture or auto focus when one is connected to the Sony FS5 II.

Q: 5. I have a wooden camera PL adapter and it came with shims, which I definitely needed to correct the back focus for use on my FX9 and Fs7. Does this adapter come with or require shims to correct back focus?

A: The Metabones PL to Sony E-Mount T CINE Speed Booster ULTRA 0.71x is designed to be used without shims and does not included shims, but they still may be necessary for some lenses. "Note: Due to the positioning of the optical elements used in this adapter, compatibility is limited to lenses whose rear element and mount won't interfere with the optics. See the Metabones website for an updated list of compatible lenses."

Q: 6. Does this item work well with PXW-FS7 and Nikon F and G lenses?

A: I bought it to use on a Sony FS100 with my Nikon lenses. I've not put it through a great workout yet but I have used it several times with no problems. It's very well built, it feels very snug and secure even with heavier lenses, though it still attaches (or removes) to the camera and lenses smoothly. As for F&G lenses, I've only used it with the F mounts, but I just stuck a G on there and looked, it operates the aperture on it as well. The aperture ring on the Metabones has no click stops, so it rolls smoothly with just a tiny bit of resistance (good). I've also bought one for using on a GH-4 which is a micro 4/3 mount. I'd recommend them.

Q: 7. I have nikon FX lense, Is this adapter work on my new A6300 ? and does it auto focus on A6300?

A: I bought it to use on my Sony A7. Unfortunately it did not work and I had to return the product. This was a number of years ago though so things may be different now. The good news was I had the option to try it and they return it when it didn't work.

Q: 8. Does anyone have experience with this adapter? How does Canon R series autofocus work with this and Nikon AF lenses? Is there a better option to leverage both ecosystems?

A: The Metabones Nikon G to Canon RF-Mount Speed Booster ULTRA 0.71x is a manual speed booster adapter. It does not support autofocus or any camera to lens communication. Because this is a speed booster it is only compatible with lenses designed for full frame cameras being used on APS-C format camera (eg. Canon C70 and RED Komodo, etc.) or using with the APS-Crop mode of EOS R3, R5, R6, EOS R and EOS RP.

Q: 9. I cant find a dedicated Speed Booster for Nikon F mount to Fuji X. I need to be able to connect a Samyang 24mm (Nikon F mount) to the Metabones Speed Booster, however I'm worried that because the Speed Booster is for an 'F mount G lens' that the F mount (non-G) lens wont work, or be able to change focus or aperture. Any experience with this? Thanks,

A: The metabones will work perfectly. You don't need to have G lenses for the adapter to work 100%.

Q: 10. Will this booster work with Sony A6000 ? Will the autofocus work ?

A: It will work with the A6000 and has the benefit of reducing the crop factor from 1.5 to 1.1 giving you essentially a full frame field of view. Unfortunately, autofocus doesn't work.
