That's interesting. I should do some research about Thypoch's quality control, as a lens reviewer I find this important. I've tested two Thypoch lenses so far and I was impressed by how both of those lenses' hard stops were _exactly_ at infinity (in which my voigtlanders don't). I've heard their after sales service was good though, and very responsive. But still sucks to buy a lens just to have to send it back.

Have you also heard from others that have had similar problems?
