I'm after a 20mm/21mm lens. Zeiss 21mm ZF/ZE would be great but it is way over my budget at the moment. One option would be Sony 28mm with a 21mm adapter, but it's all just speculation at this point. I have 28mm covered with Zuiko 28mm/2.0 and will only buy the Sony 28mm offering if it is to be something very special optically. The ULTRA wide end I have covered with Voigtlander 12mm, which by the way works very nicely with A7S.
Has anyone had an option to compare Canon FD 20/2.8 with Zuiko 21/3.5 or Nikon 20/3.5 AI-s? Of course I will be open to other suggestions as well.
Thanks in advance!
Best regards, Jyrki
