Review on 7artisans 35mm F1.2 Lens: Perfect Manual Focus for Olympus/Panasonic Micro 4/3 Mirrorless Cameras (Silver) by Chad Gravely

In the beginning the assembly was difficult: you have to make an effort and I was afraid that the camera will be scratched because 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.
