This is a blog post to wrap up my short experience with my past broken Rolleiflex Automat MX-EVS. It is sad to report that I have sold my Rolleiflex to a new owner.

Taking Lens with Zeiss Opton Tessar 75mm f/3.5

The Rolleiflex has its own characters and charm and it is quite solid in construction and I especially like its film winding crank. Unlike the Yashica, the advancement of film and shutter click can easily be felt.

I got mysterious soft and Holga-like pictures when I tested it with a roll of Ilford Delta 100. Pictures seem to be soft and out of focus all around. I looked through the lens and time the shutter in different settings and initially I couldn't figure out the issues. I discussed the Holga-like and soft pictures with others and I learned a bit about the camera along the way. It is not normal with my copy of Rolleiflex.

I learned it from others that the Zeiss Opton Tessar 75mm f/3.5 lens is quite a sharp lens and my test shots are just not normal. Possible causes of the problems

  • Taking lens and viewing lens are not in the same focal plane.
  • The taking lens front element has been reversed by previous ownership or someone did a poor job of re-assembly of the taking lens in a CLA service
And checking at the back of the Tessar lens gives evidence of the later with re-assembly of lens with scratches around the lens retaining ring.

I see the pictorial diagram about Tessar in

According to wikipedia
A Tessar comprises four elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative plano-concave flint glass element cemented with a positive convex crown glass element at the rear
It is likely that the double-concave element second from left is misplaced or reversed in the previous re-assembly.
