+ Clean processing
The adapter can be seen on the product image plastic (by the way it smells neutral / not at all), the side where the lens attaches metal. From the inside it is matt black and has fine grooves. The small pin to release the lens from the camera, also made of metal, not acting insanely stable, but has so far ~ 20x on and remove without any problem / change without participated.
+ Good handling and proper functioning
I use the adapter with my Olympus E-PL5 and the Minolta MD 50mm 1.4:
The lens snaps a well in the adapter - no play, but without excessive force. At the camera adapter is also tight, but can also be set up here well. Weight Technically it fits perfectly with my slight M43 equipment and light-tight it is.
I am deeply impressed. Since my objective Park has yet extended times abruptly :)
I do not know if it is strongly recommended, but I still have an old M42 Minolta adapter and the Combined camera - Adapters - Adapter - lens also works.
