eastman projection anastigmat 10in f8

[sun of sand]

I belive some have used enlarging velostigmats for large format and found them to be quite good
but whether thats because they were sharp as the ordinary velostigmat or as soft as the ordinary velostigmat, i dunno
i belive the ordinary taking lens is sought after more as a makeshift soft focus by unscrewing the front element a bit
but i dont pay much attention so you can look it up

I have tried a 90mm wollensak enlarging raptar on 4x5 and it nearly covers. it's actually pretty sharp in the center,too
I got it for free though

I've also tried a a cheap el omegar 75mm enlarging lens on 35 format just for kicks and while it worked i wouldnt say it was all that great
that coming from someone pretty forgiving

oh and i bought for $10
see im cheap, too
i say adventurous
a lens for the coleman enlarger?

Some have found it to be a good soft lens wide open or whatever ..never tried it myself
think there is a 10 inch version.

Since you ask for guesses, I will guess that the lens is a Tessar design and the image circle at infinity would be fairly close to the focal length.

It is probably very sharp at distances of two or three focal lengths, but might be less so at or near infinity. The lack of coating can be somewhat offset by careful use of lens shades.

This is a four element air spaced lens. Can be easily taken apart. I have one . It is a very sharp lens.
