Advertisement Posted August 20, 2021 Posted August 20, 2021 Hi anthonym3, Take a look here ROLLEIFLEX AUTOMAT. I'm sure you'll find what you were looking for!
Danner Posted August 20, 2021 Share #2 Posted August 20, 2021 Don't know for sure, but generally, pre WWII lenses are not coated. Link to post Share on other sites More sharing options...
Reini Posted August 20, 2021 Share #3 Posted August 20, 2021 A few from the last Automat with Xenar 3.5 Lenses are coated. https://www.acyclopseye.com/rolleiflex-automat-original 1 1 Link to post Share on other sites More sharing options...
250swb Posted August 20, 2021 Share #4 Posted August 20, 2021 But not from 1942. An interesting web page though, thank you. Zeiss started coating lenses in 1936 (I think) but what with a WWII going on I think that coated lenses began in general terms very soon after the war ended.

Since I am not involved enough to buy Prochnow or Parker's books, it was great to see a detailed writeup on the earliest Automats. I own the 1937 version without the shutter release safety lock - and it was my first time to see that subject covered in such detail. 1 Link to post Share on other sites More sharing options...
250swb Posted August 23, 2021 Share #6 Posted August 23, 2021 I have an Automat K4b from 1956, a superb camera and I've just had it serviced after it developed a sticky shutter but once again it's as smooth as butter to use. I've also treated it to an Oleson Bright Screen which made a big difference to my Rolleicord Vb2, it should be even be slightly better with the Automat as the viewing lens on that is f/2.8 and not f/3.2.

earleygallery Posted August 23, 2021 Share #7 Posted August 23, 2021 Advertisement (gone after registration) If uncoated it may have developed a natural coating, or 'blooming'. Link to post Share on other sites More sharing options...

That is typically easy to identify as an uneven "oil on water" reflective look. If coated by third party, only the taking lens would normally be coated, and sometimes only one group, for example the front group of a Tessar or Triotar.
