But as to the issue of black versions being available, I can say I just received a replacement black lens via UPS yesterday, after Thypoch told me they would send me one under warranty when my first lens failed. The serial number on the new one is actually lower than on the old one, for whatever that's worth. I haven't had it mounted to a body to test yet so I can't speak to performance, other than to say that the aperture on the new one definitely feels better than the old one did.
Bought a couple of Thypoch Simeras (50mm & 75mm) earlier this summer and had issues with both. Contacted their support directly, and with the 50mm they informed me the (lens mount light leak) was a known QC issue, but they had a fix. So it may be that the lower serial number lens you got was (hopefully) fixed from one of their initial batches.
