  1. Re: Emil Busch Petzval generation transition history: sampling needed to testify & mo

    Well, perhaps not fitting matching, but perhaps ensuring identity BEFORE use of serial numbers.
    In other words - this is the 8th lens made in a batch of 8 (or 10 or 12) made in the workshop of this...
  2. Re: Emil Busch Petzval generation transition history: sampling needed to testify & mo

    What a super lens - and just the right size for 8x10 without being nervous about coverage!
    It is obvious that Busch wanted to try just every feature novel feature that was being launched in Paris....
