Metabones MB_SPPL-M43-BT1 Overview

Boost the performance of your Zeiss CP.2, CZ.2, or CP.3 PL-mount lenses when mounted to your Micro Four Thirds camera with the Speed Booster Ultra 0.71x Adapter from Metabones. This adapter uses specialized optics to reduce the effects of crop factor on mirrorless cameras, offering a magnification of 0.71x to make the lens wider.

Precision-crafted from brass and given chromium plating, the adapter is designed for daily use and guarantees infinity focus.

Additionally, it has a detachable Arca-type compatible tripod foot for simple mounting to a variety of tripods.

This adapter is designed exclusively for Zeiss CP.2, CZ.2, and CP.3 lenses. Any attempt to mount a lens that is not listed as compatible with this adapter may result in damage to the lens and the adapter.

Don´t use with a GH5!

By David
Rated 1 out of 5
Date: 2019-08-07

I bought this to use with my GH5 and canon lenses. ALL of the lenses I have used cast a serious blue flare in the center which makes the image almost unusable. This happens when ANY sort of light hits the lens from the front. It is unlike any normal flare from any normal lens. Look this problem up on the internet. You will find others with the same problem. Just saying... stay away if possible.

Perfect! (For my needs)

This was a hard purchase to make since I didn’t know if it would work and there was very little information about its compatibility with most lenses. I bought it because I have the Blackmagic pocket 4K and I wanted to shoot anamorphic lenses. I rented the SLR magic anamorphot PL lenses and both the 35mm and 50mm fit this adapter. I didn’t rent the 70 so I can’t soeak to it’s compatibility, but based on photos of the 70, I don’t think it would fit. But the 35 and 50 worked beautifully. The adapter perfectly eliminated the crop on these lenses that would’ve been present because of the small sensor. And as advertised, I got an extra stop of light coming into the camera. So all in all the speedbooster did its job wonderfully...with THESE lenses. People have said it doesn’t work with many lenses. So it’s a gamble. However if you’re itching to shoot anamorphic, and you have the pocket 4K...and you want to use SLR magic anamorphics...this is for you!!

Will this work with the DZOFilm Vespid prime lenses?
Asked by: Charles
The Metabones Speed Booster Ultra 0.71x Adapter for Select PL Lenses to Micro Four Thirds Camera is only compatible with PL lenses that have a rear protrusion of less than 14.5mm. As the rear protrusion of the DZOFilm Vespid primes are only 14.3mm, it should be compatible.
