Kodak, Schneider, Wollensak made lenses of approximately the same focal length. Thus there are equivalent choices in a given focal length between a Ektar, Xenar or Optar.
Most Graflex Optars are made by Wollensak, but later (post 1965) Optars are manufactured by Rodenstock.
These lenses are 3 group/4 element ``Tessar'' type lenses with a 55 degree circle. The Ektars were probably the best all around quality, with Xenars next, and Raptars and Acutars third. They are fairly close if in good repair and not mistreated.
The Polaroid 110,110A and 110B roll-film cameras can often be found very inexpensively. They are fitted either with a Rodenstock Ysarex 127/4.5 or Wollensak Raptar 127/4.5.

Goerz | Super Dagor (f8) | 3 5/8", 4 3/8", 6.5" |
The Dagor and the Schneider Angulon are true symmetricals (f6.8) but can cover over 70 degrees at f22 and 80 degrees at f45. They are of six-element, two-group construction. With so few air-glass interfaces they are resistant to flare; uncoated Dagors will be acceptable.
The Dagor name comes from ``Double Anastigmat Goerz.''
