This is a simple easy to use adapter that feels durable and well built.

Early review: I disregarded the recommendation not to use this adapter on the Sony A7II. The fit doesn't give me any cause for concern. No play, but no unexpected resistance when attaching it, either. Functions well with my collection of Nikon lenses.

Very well constructed. Excellent materials and fit & finish. Highly recommended.

The adaptor itself seems to work fine. I've used it with lenses like the Helios 44M 58mm and Helios 28mm wide-angle with much success. However after shooting with it for several days, I've noticed maybe a dozen fine metal particles covering my A7ii's sensor. I can't be certain whether the particles came from a lens or the adaptor itself, but it might be a good idea to leave one of these adaptors on each M42 lens you have, or purchase a more expensive one that won't wear.
