Metabones Canon EF Lens to Sony E Mount Speed Booster - $250 Realize the full potential of your full-frame Canon EF-Mount glass on your APS-C and Super35 format Sony E-Mount cameras with this Metabones Canon EF to Sony E-Mount Speed Booster. Utilizing advanced optics, this adapter will bring back the full-frame equivalent field of view by around 0.71x, negating the crop factor of an APS-C camera. This also increases the maximum aperture by 1 stop. This adapter works wonders on vintage lenses like the Helios lenses that really shine when using the outter reach of glass elements for the character they are known for. Also, this adapter has the electronic contacts, so autofocus on EF lenses should be possible, I do not have any EF lenses to test this. This adapter also has the USB-C port to update firmware to support more lenses if you need to. The exterior shows some signs of usage, but as you can see from the pictures, the glass elements are perfect and will not disappoint. Comes in the Metabones case and both caps. Sale is for cash only, pick up only in Kitsilano. Pick up in Kitsilano only, Cash Only. Thanks.
