Any info. on Suter lenses

..

eddie, how much your "giant" covers? 500mm should be near. Did you shot with it?

edit: ok, just saw you put it for sale.

These giants must have been a Swiss contribution to Process lenses - given the size and the original aperture control on your "small" version Eddie.

dunno...
I have a very, very heavy Series II 520mm F 6.3, and it doesn't strike me as a process lens...

what to use it for... I don't know yet....

Has E.Suter's ever built Anastigmat lens with 6 lenses in 2 groups (3x3)? I have checked mine 500mm again (Pat. 21872) and it seems it consist 3x3 (see photo). VM says nothing about Suter Anastigmat 3x3... only 4x4.

Thanks for posting! The closed off plate for extra stops/filters suggests a process design. Couldn't there be an extra "balsam join" at the front "corner"?

[renes]

Yes, there is a small balsam separation on edges of the front lens. I think the lens was coated in the past. Not easily, but it can be seen on right anglel of lighting. So it's 3x3 Suter's process anastigmat? The bottom cell looks very big/bulky. Do this process lenses differ to common Anastigmat Series I?

[Steven Tribe]

They are a lot bigger and very much more expensive!
The x section of this lens is shown as Suter 001 at the bottom of vademecum. Note there is an edge lamination which may be difficult to see!

[renes]

just small balsam separation on one part. What about 3x3? Could this lens be 4x4 design? I am going to sell it and do not want to mislead.

[Steven Tribe]

Everyone says this is a 4 + 4 design. A modified Dagor - but probably no better (not necessary, either!).

[renes]

Some say it could be a Simon Octanar copy.

[Steven Tribe]

Which is also a 4 + 4 (Octa = 8) and also probably a Dagor design!
