Q: 9. Beware crop factor, not mentioned in spec. What % of area of FULL FRAME is lost, to MFT image?

A: This adapter is an extender, not a cropping device. I bought a Vello adapter for my Canon EOS6D and 7D to fit my old FD canon lenses.The Vello extender increases focal length by 1.25x and add one f stop.EOS 6D (full frame)-Vello adapter- FD 50mm f1.4 lens become a 63 mm f2 lens. No cropping with Vello adapter.EOS 7D (1.6 crop)-Vello adapter-FD 50mm f1.4 lens become a 1.6(crop)x1.25(extender)=100mm f2 equivalent view compared with full frameIf the MFT adapter is similar to one described above then:FD 50mm f1.4 on MFT sensor (2.0 crop) + extender would be: 2x1.25x50=125mm f2 equivalent view . I am very happy with the Vello adapter. I took great photos with my old FD canon lenses. They are sharp and soft. Characteristics difficult to find in new lenses.
