Hello
Can someone tell me what is the difference in performance, if any, between these two M42 lenses:
Pentacon f=3,5/30 mm and Meyer-Optik Gorlitz Lydith f=3,5/30mm
I think that they are optically equivalent (I may be wrong) and I know their prices are substantially different, but are there other differences??.
Thank you for any information
Joao
