159mm wolensak

[tim_kimbler1]

I just got a 159mm Wolensak F12 lens for my 8X10. I'm looking for information about the lens from folks using it. I will be using it for B&W Landscape, contact, both Brown and AZO prints. Any information would be great.

This cut and pasted from another news group:

"The table I have lists the 12.5 Wollensak as having a 379 mm

image circle and 100 degrees of coverage. That sounds like it

could be about right. I believe you need to stop right down to

f16 or f22 when shooting to get rid of residual aberrations, but

this is only a guess based on info provided on lenses of similar

vintage (the Angulon) where the wide open aperature is for

viewing only."

"I don't have access to pricing information of the period and was not

aware that the 159mm f/12.5 Wollensak Extreme Wide Angle lens was

marketed as a cheaper version of the f/9 specimen. It was my

impression that the difference is somewhat like that of the Protar IV

and Protar V, in that the later, though of smaller maximum aperture,

has somewhat greater coverage."

"Many years ago I had an oppoertunity to compare the f/12.5 and f/9

versions of the two Wollensak EX. WA lenses (they were both

Velostigmats) and the f/12.5 model did indeed have greater coverage.

Since coverage is a really important feature this fact should explain

why the f/12.5 model has a market value close to the f/9. In fact for

my money the greater coverage would make the f/12.5 model more

valuable."

I have the 9.5 and couldn't be happier - unless of course what they

say about the 12.5 is true.
