I would love to know why the Industar was not available for the Kiev. It fits into the J-8 Kiev mount. Was it just too low cost? The Kiev got the Helios-103, the screw mount cameras got the Industar.
The "Specs" on the Helios are even a bit better than those posted for the Industar.
Brian,
Let me venture into this speculation
🙂 Years back we asked James Marc Small a similar question.
Arsenal/Kiev may not have opted to make Tessar types for their cameras since they already were capable of making the fast Sonnar types. Considerations which a factory in a market-oriented setting do not necessarily hold true in a similar factory operating under socialist conditions. Besides, they may be so 'proud' of their abilities that they saw no need to produce a cheaper, simpler lens for their cameras.
From their production point of view, there was nothing in their way to make anything else than the Sonnar types. Or it could be that there was no perceivable/practical reason to make anything else. Since the Kiev were considered as premium RF, they deserved nothing else but the best of the lenses.
The LTM rf from FED or KMZ (Zorki) were considered second to the Kiev. Thus most of them were given the 'cheaper' Tessar type lenses. FED never offered anything else than 3.5 or 2.8 lenses for their cameras. KMZ at least made it possible to choose from several- the slower Tessar types or else an LTM version of the Sonnar derived Jupiters.
Perhaps for the same reason, there were no Tessar type 85 or 90mm lenses made by the Soviets either. Only the 2/85 Jupiter became available. FED did make 100mm version of the 'mountain' Elmar before the war, but once the CZ blueprints were given as reparation to the Soviet camera industry, nothing of the sort was made anymore.
Helios and Jupiter, being more complex lenses will always have better specs (in as far as quantitative results from test charts go) than the simple Tessar derived lenses. For instance, in ORWO film data, two resolution figures are always given: a lower one derived from using a "Tessar" type lens, and a higher one derived from a "high quality" lens (no lens description given).
