By on

The new Metabones EF-EOS M Speed Booster ULTRA 0.71x makes full-frame Canon EF-mount lenses one stop faster, 0.71x wider and with increased MFT on Canon EOS M cameras.

Full-frame Canon EF-mount lenses are now one stop faster, 0.71x wider and with increased MFT on Canon EOS M cameras. The 4k/UHD video crop on EOS M50 can also be mitigated with third-party APS-C lenses using this Metabones Speed Booster. Some Canon EF-S lenses may be modified to fit on the Speed Booster but Metabones cannot be held liable for any issues arising from modifications. Using APS-C lenses with Speed Booster for still photography or full HD videography may result in vignetting.

Metabones EF-EOS M Speed Booster ULTRA 0.71x is available right now for USD 479.00 plus applicable taxes, duties and shipping, from Metabones’ web store and its worldwide network of resellers. See: EF-E Speed Booster ULTRA 0.71x.
