Review on 💡 Commlite CM-AEF-MFT Booster: Canon EF Lens to M4/3 Micro Four Thirds 0.71x Speed Booster Autofocus Adapter for Panasonic GH4, GH5, GH5S, GF6, GF1, GX1, GX7 & Olympus E-M5, E-M10, E-PL5 by Kevin Stephan

The Commlite Ef to Mft Adapter is great if you want to get a speed boost for your Micro Four Thirds camera, it allows you to control the lens aperture from the camera. There is a glass element that offers 0.71x magnification. What I like: Electronic iris control Metal lens mount Solid build quality Comes with tripod mount Good image quality for the price What I don't like: No Allen key to remove the tripod adapter. When the lenses are wide open, there is a loss of detail. (You can look at the images provided.) The autofocus isn't great. Overall I feel it's a great little device that lets you use EF lenses on Micro Four Thirds bodies.
