History
Spectros, a small Swiss optical firm, supplied Pignons with one lens: the Alorar 50mm f/3.5, a four-element Tessar-type standard with a manual diaphragm to f/22, weighing 85 grams and focusing to a metre, introduced in 1953. It was the entry-level lens for the Alnea 4 and 5 — the copy-stand and no-rangefinder bodies — at a time when the Kern Switar cost as much as a good camera. Production is unpublished and no review has been found.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.
