Re: dreamy Nikon lenses

when you're done playing, let me know what f.l. it is, I've been looking for an affordable 159 for the 8x10. (shutter, working or otherwise not needed)

Thank you all for the comments on varying the elements. I have
wondered if any lenses were made with doughnut shaped stops (open in
the center and around the edge) so as to have a sharp image and a soft
flaring image together.

Sam, I think I might have one of those Wollensak Extreme Wide Angle
lenses around. I'll look into it. Thanks,

I agree with John that the best way is to enlarge the aperture: try that
with any disposable plastic camera lens and you've got it.

What focal length and film format are you trying to use? Here is a solution
for 4x5 and 5x7: the Wollensak Extreme Wide Angle 12.5 lenses intended for
4x5 and 8x10. Each can be found quite inexpensively. If you enlarge the
aperture from 12.5 to about f/9 (as far as it can go) you'll get very
beautiful soft focus. Every bit as nice as the best. Matter of fact, if you
point the camera at say sunlight dancing on water, I bet you'll be
mesmerized by the image on the groundglass.

To the lens experts out there...

I have a question about using an old lens as soft focus. Someone
mentioned that an old triplet could be made to give that soft halo
effect by moving the front element out a bit to introduce spherical
aberration. Do I remember that right? If so can this be done with some
of those old lenses I have laying around that have what I take to be a
front pair and a rear pair each mounted in a brass ring and threaded
into a brass tube. Can the space between the front and rear elements
be varied by screwing them out a bit and get any of these effects, or
by seperating the front pair and placing a shim between them in the
brass mounting ring?

Hopeful and expectant,
