Have the rings just screwed with joy on my Sony A7. Unfortunately, too early happy. The first ring is very loose at the camera circuit, the second ring has so so game that there arise on the first ring with safety light spots. An expensive / heavy lens I like not even bolted to the rings at the loose construction. In addition, a strong edge (no vignette, but a real black border) with focal length to 85mm-turvy.
Either I caught a Monday model, or the rings like so not with an E-mount or Sony A7.
The first time that I'm going to send the article back.
