Hello all,

I did some searching, and looked on Schneider's website, but wanted to confirm what I found (did not find).

How many versions of the 58mm f/5.6 Super Angulon were made? I can only find one, which is the XL version with a 166mm image circle. Is this the only 58mm f/5.6 lens for 4x5 that Schneider made?

Also, when did this lens start production? Thanks.
