Difference between Super Angulon 120/121mm.

[Bill_1856]

What's the difference between these two f:8 lenses?

[JW Dewdney]

About a millimeter.



Sorry - couldn't resist. I'm an ass.

Like the old cigarette commercial: just a silly millimeter longer.

The main difference is that the 120mm is multi-coated, whereas the 121mm is single-coated.

I have the latter, and it's an excellent lens. I figured that, if it's good 'nough for Ansel Adams, it's good 'nough for me. One can also find them at quite reasonable prices.

The 120 could be a newer design but not sure except multi-coating !!.
The vintage lens data on schneideroptics.com says : 513 grams for the older 121, which could be understood as a being a very different design from the 120, listed @ 700 grams on the same web site.... or is-it a misprint or weight without shutter ?
The 1963 vintage brochure on the German Schneider web site says : 675 grams for the SA 121... on a Compur shutter.
But other brochures quote differents focal lengths and weight...
