  • Related Questions and Answers

    Q: 1. Does this adapter support autofocus on either SONY/Minolta's SSM af lenses or on the older SONY/Minolta screw drive af lenses?

    A: Autofocus is not retained when using this adapter.

    Q: 2. Apologies, I meant Nikon AF lenses. - Mark ? in Canada

    A: I see the correction you made but that still is not the correct adapter.This will work on your camera with the Nikon AF lenses, Metabones Nikon G Lens to Sony NEX Camera Lens Mount Adapter (Matte Black) B&H # MENFGEBM1 MFR # MB_NFG-E-BM1.

    Q: 3. Does this adapter can be use on Sony a77 and Sony a99 ii for Sigma 800mm F-mount with AF? If not what adapter do you suggest to be able to use this camera with AF?

    A: No, the Metabones Nikon F-Mount Lens to Sony E-Mount Camera Speed Booster ULTRA will not work with the Sony A99 or the A77: https://bhpho.to/2dRc0U1

    Q: 4. Will this booster work with Sony A7sii?

    A: No, this booster dont work with Sony a7sii, because this booster is for crop sensors

    Q: 5. I have some late 80's early 90's Minolta AF A-mount lenses , like the 100mm 2.8 / 50mm 1.4 / and 500mm 8. Would these autofocus on the sony 7rii in Video Mode? Thanks

    A: A to E Mount adapters can give you autofocus. https://bhpho.to/2qaXWtu

    Q: 6. May I use this booster on A7 MarkII to mount Sony/Minolta Alpha lenses?

    A: The Sony A7 II uses Sony E-Mount lenses. The Metabones Sony A-Mount Lens to Sony E-Mount Camera Speed Booster ULTRA (B&H # MESPAEBM2 MFR # MB_SPA-E-BM2) will allow you to use Sony A-Mount lenses with the E-Mount A7 II.

    Q: 7. Will this work with the Non AI manual Nikkor 50mm f1.4 lens without the rear lens element touching the speed booster front element? The competing brand I have tried cannot focus beyond 7ft or so because the elements collide.

    A: No.

    Q: 8. Will IBIS (in body image stabilization) work with this adapter?

    A: Yes you can use the in body stabilizer with this adapter.

    Q: 9. Do this works in both cam 1, cam 2 and cam 3 lenses?

    A: Yes, this adapter works with all Leica R lenses.

    Q: 10. 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.

    [1/4"-20 Female] Solid build with great optics.  This company is the go to in speedboosters and the product proves that to be true.


    A must for your Nikon lenses and micro 4/3 camera system.

    [1/4"-20 Female] I tested this vs. some $100 knock offs (2 different styles that I own). Those are clear at 4x in my GH5's camera viewer, the Metabones is clear at 8x. I saved money on the FD lenses, and will gladly spend some of what I saved on the Metabones to have them as sharp as can be.

    [Leica L] Love this item, works great and is all-around super. Expensive for sure, combined with paying full price for returned item makes me a little salty.�

    Nice adapter but taking my business elsewhere from now on.

    [Leica L] Beautiful clarity. Makes the GH5 a very usable low light camera. Widens the viewing angle without distortion.

    [1/4"-20 Female] At first I was worried about vignetting but the speedbooster straight out the box worked splendidly. The added stops also supplemented the EF Sigma 18-35mm f1.8 and gave me an f1.3 which was perfect for low light shots

    [Leica L] Metabones is a true champ when it comes to lens adapters. This adapter will not only let you use your canon EF lenses, but it will actual focus more light in onto the sensor adding almost a full stop. I love canon L series lenses but I also love my GH5. This was a great way to get the best of both worlds.
