Review on 📷 VILTROX EF-M2II Speed Booster Micro 4/3 Focal Reducer Adapter EF Mount to M4/3 Camera GH4 GH5 GF6 GF1 GX1 GX7 E-M5 E-M10 E-M10II E-PL5 by Paul Barnes

I bought these to fit Canon EF lenses to my LUMIX G7. So far I'm very happy with it. The build quality is almost all metal and feels solid. Autofocus, aperture control and EXIF work perfectly. Autofocus is a bit sluggish, but that's to be expected when fitting non-native glass to any system, and it's not a big deal for photos. Definitely a great and cheap alternative to Metabones. Image quality is good and fairly sharp around f/2 and above, softening everything below but still acceptable. It attaches perfectly to the G7 and the lenses attach perfectly with no issues.
