90mm Angulon vs. 90mm Super Angulon vs. caltar 90mm

[QUOTE=Christopher D. Keth;217231]I'm in the market soon for a nice 90mm. It's a length missing from m arsenal.

I've been looking at some and what exactly is the difference between angulons and super angulons? I like the angulon from the perspective of weight and speed, but is there a big down side?

How are the 90mm caltars? They look remarkably similar to a super angulon. Coincidence or no?[/QUOTE

There are a wide variety of Caltars. I think the first ones were made by Ilex. (Not positive on this.) Later, Calumet used Schneider lenses and ended up with Rodenstocks. For example, the Caltar S-II is a Symmar-S. The Sironar-S lenses were never available under the Caltar name.

If you know what you're purchasing, you can save money purchasing Caltar and still get the same lense you might have considered under the Schneider or Rodenstock names.

Ole -- is the Angulon as sharp in the corners (when stopped down) as the SA?

The Caltar W-II 90 f8 that I recently bought is quite nice, sharp edge to edge with a plenty large IC, I'm quite happy for not much $$$ (in reality the Caltar W-II is a SA in Calumet clothing, fyi....)

Yes, but the corners are closer in.
(sorry - just couldn't resist it. )

More seriously, I use my 90/8 SA more often as a "superwide" on 5x7" film. Even then the corners are sufficiently sharp (IMO). The 90/6.8, as can be seen from my informal unscientific test, goes to mush long before it reaches the corners of a 5x7". BUT: If you ask about the corners of a 4x5" film, straight on with no movements, a late 90/6.8 is as sharp as a 90/8. A pre-WWII 90/6.8 is less sharp in the corners, but has a slower "degradation" which for a given definition of "sharp" allows it to be usable with slightly more movements.
