Sources of data

  • mamiya/sekor interchangeable lenses for 1000TL and 500TL booklet.
  • mamiya/sekor DTL series booklet by Ponder & Best (May 1968).

From the editor

Mamiya literature states that the closest focusing distance is 2 ft (or 24 in.), which is equivalent to 0.6m. We were able to find photos of this lens with the closest focusing distance (CFD) of 0.4m, however, we do not exclude the possibility that there was a version with the CFD of 0.6m.

The lens is suspiciously similar to the TOKINA WIDE-AUTO 1:2.8 f=35mm (not in the database) with the CFD=0.6m or Tokina WIDE-AUTO 1:2.8 f=35mm (not in the database) with the CFD=0.4m.
