Review on 📸 7artisans 35mm F1.2 APS-C Manual Focus Prime Fixed Lens for Compact Mirrorless Cameras M4/3 Mount - Compatible with Panasonic G1 G2 G3 G4 G5 G6 G7 GF1 GF2 GF3 GF5 (Black) by Glenn Cho

It was difficult to install at first: you have to use extra force and I was afraid of scratching the camera as the lens mount has sharp edges. Unfortunately, once fitted, the lens dangles in place and some contacts may shorten as I have a black screen every other time. The quality of the optics is normal, but the m43 mount needs some work, polishing and better quality control. I don't want to damage my camera by checking it further and the lens is going back to Revain.
