Thypoch Eureka 50mm f/2 Aluminum Reviews

Terrible Build Quality

By Alex
Rated 1 out of 5

I bought this on Amazon due to faster shipping but had to warn others here. The inner barrel that extends and retracts is not well fitted to the outer barrel. It wobbles and spins freely. Overall the lens and included filter and hood feel cheap, which at $499 it is relatively cheap compared to the Leica it tries to imitate. I actually had to repair the hood as the locking mechanism was installed incorrectly by the factory. Additionally, I think it is likely going to be sucking in dust into my M11-P. I plan to return the lens to Amazon.

Beware: It may not be compatible with your camera

I’ve bought this lens for my M10 and M3. While it worked perfectly fine on the M10, the lens didn’t mount properly on my M3. It couldn’t “click” into the mount. I’ve tried 3 variations of this lens and they all behaved the same. I hope this review helps those who are looking to use this for old film Leica bodies. While I can only speak for my M3, please make sure to test this lens before purchasing it.

Would this work on an Epson RD-1?
Asked by: Carol
The Thypoch Eureka 50mm f/2 Lens (Leica M, Aluminum) is M mount like the Epson R-D1. However, the lens does stick out in the back a bit, and it might hit the camera's sensor.
