History
The Alpa-Altelar 90mm f/2.8 is the second of A. Schacht’s two Alpa lenses: four elements in three groups, a sixteen-blade preset diaphragm from f/2.8 to f/22, 255 grams, close focus 60 centimetres, introduced in 1957. It sat in the Alnea catalogue beside Schneider’s Tele-Xenar 90mm f/3.5 as the faster of two 90s until Angénieux’s Alfitar f/2.5 succeeded both around 1960. The name is a hazard: SOM Berthiot’s Altelar 145mm f/4.5 of the 1947 range is a different lens by a different maker. Production is unpublished and no review has been found.
This history is AI-written, from the sources listed at the foot of the page. Where the record is silent it says so rather than filling the gap — but no human wrote these sentences.
