Using a Leica Summicron-R 90/2 pre-ASPH. Works fine with a nice solid feel. It overshoots infinity focus by a small amount. Better than not reaching infinity, though.Mounting is ever-so-slightly loose. The mechanism that secures the Leica lens to the adapter has some play to it, resulting in *very* minor rotational play. I don't tend to notice it in active use of the lens. I am concerned, however, that this part will wear down from stress.

LR-E-mount : fits well both camera and lens connection, sturdy build, great value for money. no play and feels solid. sensor lens distance is spot on.LM-E mount: adapter-camera: fits well, adapter - lens is very tight, requires a little force to full mount: Makes it very secure with no play on the other hand. sensor lens distance is also spot on. Need to be a little careful when changing lenses but at these price i can buy one for every m lens. could probably be better but for casual use it's all you need and better than wobbly connections. great value for money!

Typical K&F quality giving a very good value. Lens fits smoothly and locks in/out without a struggle as found with other adapters. Excellent service by dealer and by Amazon.co. I must compliment the lens adapter companies for having so many adapter choices which allow us to use all the older exceptional lenses on our modern digital cameras.
