Eric,
Wow! The mythical 80mmWF Ektar!! I have heard of, but
never have seen that baby.
When I wanted a wide angle lens for a sheet film camera, I
got a 90mm Angulon for my
4x5. People tell me about a 65mm Schneider lens for the
Baby Speed Graphic. 80 mm
would not have cut it for a 6x9 camera; at least not for
me. 38mm is just dandy for a
6x6 camera, isn't it? I love it.
Jerry
The WF Ektar is a four element double gauss lens. A
number of other manufacturers have made semi-wide-angle
lenses based on this design. One of its virtues is very good
color correction which I think was important to Kodak at the
time. These are called "wide field" lenses because they are
limited to less than about 90 degrees, most wide angle
lenses will cover a larger angle. The Super Angulon is
probaby a superior lens, at least it has wider coverage and
has a bit less fall off. The orignal Angulon is a variation
of the Dagor. The quality varies a lot for the type and the
original design, as shown in the patent, was awful. It was
certainly redesigned at some early point. I have a pilot run
Angulon which has such bad color fringing as to be unusable.
The main advantage of early WA lenses, like the Angulon
and WA Dagor and the WF Ektar is small size and weight.
Roosinov type lenses like the Super-Angulon have oversize
outer elements and are quite large and heavy for their focal
length and speed.
