Jerry Lehrer once recommended that very lens as an
excellent 2 1/4 enlarging lens. "the one with the large
knurls". Not surprised at all.
I've been shooting with an ancient 12 inch Kodak
Anastigmat in a barrel in front of a Packard. absolutely
excellent. Even or especially wide open. Amazing. kodak
did good lenses.
Kodak made two series of lenses under the name "Kodak
Anastigmat". One was the 30 series the other the 70 series
(I have no idea where the numbers came from. 30 series
lenses are Tessars, 70 series are dialytes (four element air
spaced). Some of both lenses are included in the lens design
survey program LensVIEW. They vary in quality but some of
them are excellent. For the most part these lenses were
designed in the teens and twenties when C.W.Fredrick ran the
Kodak lens department. Before I got LensVIEW I was under the
impression that these early Kodak lenses were mediocre and
that the really good lenses were designed after Rudolf
Kingslake became head of the department. Not so, many of the
earlier lenses were very good. After Kingslake took over
there were some really excellent lenses, as good as anyone
was making. Kodak Anastigmat lenses were often found on
cameras made by Folmer & Schwing. Of course they were owned
by Kodak for a couple of decades. 70 Series K.A.s were
pretty much standard on Graflex SLR's where the somewhat
narrow coverage of this type of lens is not a problem. Speed
Graphics usually had Zeiss Tessars on them rather than Kodak
lenses until around 1940 when Zeiss could no longer supply
lenses. Then the standard became the Kodak Ektar in a Kodak
shutter.
A lot of the lenses used on Kodak's cheaper cameras up to
around 1930 were made by Bausch & Lomb, who also made a lot
of shutters for Kodak.
