Was coding 50mm lenses as 85 or 100mm.
The tool is easy to handle and the codes work.
Delivery and all OK.
I bought the 6-bit encoder kit which includes both a black and a white pen. The (3D-printed?) tool works reasonably well by clicking in place in the locking hole on the mount. While it is solidly made, it is a bit thicker than I'd prefer. The pen gets obstructed by the overly thick plastic frame when filling the designated areas. Not a big issue, but it means you have to angle the pen in all directions in order to fill each area completely. A small issue, yes, but there is room for improvement in that regard. The printed list of 6-bit codes was nice to have, but the one I got wasn't up-to-date: When I wanted to encode my Nokton 50mm f/1.2 as a Noctilux-M 50mm f/1.2 re-issue, that code was missing, but I found it on the net, so no big deal. Am I happy with the purchase? Yes. I am just nitpicking in order to present potential buyers with possible minor issues they may encounter.
It's a simple and effective way to give your lens a 6-bit-code. My Leica M EV1 recognised the code without any problems. The setup was a piece of cake. I would definitely recommend this product to any Leica photographer using third-party lenses.
Easy and worked well for my two Thypoch lens
