Related Questions and Answers

Q: 1. Can I use this with a Sony FS7 and a Fujinon XK20-120mm T3.5 Cabrio Premier Lens (PL Mount) ? Will there be cropping?

A: The Metabones PL to Sony E-Mount T CINE Speed Booster ULTRA 0.71x B&H # MEMBSPPLEBT1 requires that the lens be full frame. Unfortunately, the Fujinon XK20-120mm T3.5 Cabrio Premier Lens is not full frame. Therefore it is our opinion this combination will not be able to work. You can use this straight adapter to mount the lens to the FS7 and fully utilize the lens. Metabones MB_PL-E-BT1 PL to E-Mount Adapter with Internal Flocking B&H # MEMBPLEBT.

Q: 2. 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: 3. On the metabones website, it only lists certain zeiss lenses as compatible with this speedbooster. Is it true that these are the only lenses you can use?

A: The Zeiss lenses listed on the Metabones website for the Metabones PL to Sony E-Mount T CINE Speed Booster ULTRA 0.71x are guaranteed to work since the adapter was designed exclusively for them.

Q: 4. IS there a polarizer available?

A: For the Mavic 3 Pro we offer PolarPro Circular Polarizer Filter for Mavic 3 Pro (BH #POM3PCPF • MFR #M3PRO-CP) and Freewell Circular Polarizer Filter for DJI Mavic 3 Pro (BH #FRFWM3PCPL • MFR #FW-M3P-CPL).

Q: 5. Will this work with Cooke Minis?

A: It will not. Cooke Mini lenses cover a Super 35mm Sensor, this is a Speedbooster that requires lenses which cover a Full Frame Sensor. You would need to use the standard, none speedbooster adapter instead. https://bhpho.to/2CkcWYK
