I just received an old Rolleicord Ia Mod. 1 from 1936-7. All as expected except the taking lens a CZ Triotar 4.5 is coated, both front and rear element of the front group.
I realise that this must have been a later upgrade because not even my then state-of-the-art 1937 Rolleiflex Automat v.1 w. a CZ Tessar 3.5 is coated.
Yet it seems a bit excessive to spend money to have such a relatively modest lens coated, can't have been cheap.
Does anyone here know if the Triotar 4.5 was ever sold coated from the factory?
I can see that from 1939 the Triotar 3.5 started shipping, and I would imagine that this would be the obvious candidate for coating when that became a standard feature.
Any thoughts?
