F5.6, 210mm/F12, 370mm Schneider Symmar Convertible lens.... Anyone know ahead of time or will I just have to check it? Thanks!!!

Mine is single coated. I also really like it, for what it is worth.

I believe all of the Symmar convertible are single coated.

 

[David A. Goldfarb]

I think so too. They are generally of 1960s-70s vintage.

Some of the first triple-convertible Symmars f:6.3 may have been uncoated, but all f:5.6 convertibles are single-coated.

You can date your lens from the serial number table at http://www.schneideroptics.com/info/age_of_lenses/.

AFAIK, all post-WWII Schneider lenses are at least single coated. (Perhaps a very few exceptions on the resumption of production post war ???) Early ones have a triangle symbol to advertise this feature. The triangle symbol was dropped after a few years, by which time single coating was universal and featuring it was no longer a selling point.

(Schneider began multicoating some LF lenses in 1977, after the end on the plain Symmar series -- see http://www.schneideroptics.com/info/faq/large_format_lenses/.)

I was researching a 180mm symmar-S (a generation after the convertibles,) and Chris Perez's comparison site listed 2 lenses, both Symmar-S, one was MC and the other was single-coated. The resolution of the single (1970) was well above the MC version,(1980) FWIW. David O'Connor
