The Hermagis Aplanastigmat 1:6,8 is an anastigmatic 6-element version of the Aplanat. It was announced as new in advertisements of 1898, and described as a universal anastigmat.[1]
Variants
- Aplanastigmat No. 8 — 140 mm f/6.8
- Aplanastigmat No 8 140m/m (for Vélocigraphe)
- Aplanastigmat 1:7 f=140m/m
- Aplanastigmat 1:6.8 f=170m/m
- Aplanastigmat 1:7 f=210m/m
- Aplanastigmat 1:6.8 f=210m/m
- Aplanastigmat 1:6.8 f=270m/m
- Aplanastigmat 1:6.8 f=310m/m
- Trousse aplanastigmat lens kit (convertible lens in casket)
Aplanastigmat lenses were also offered or even made by
- P.J. Plum, Lièges
- C. Holtzem, Elberfeld[2]
- W. Recker[3]
- Aplanastigmat Extra Rapid
- E. Fischel Jr. Amsterdam[4]
- Paul Loewe[5]
- Waldemar Jacobsen, Wien[6]
- E. Welsing, Amsterdam
Because of the similarity of the name, collectors often speculate that Hermagis might have been the maker; the reality of the situation is likely to be more complex with several French (and possibly German) OEM supplying custom-engraved lenses.
