    Distorted lens

    Does anyone know of a lens that produces a distorted image, kind of like a Lensbaby for 4x5? I really like the tunnel like focus effect, but don't care for spot focus filters.

    Use a magnifying glass. The center is more or less sharp while the edges totally smear. At least that's the way the one I made looks.

    For a tunnel focus look, take the front cell off a tessar lens (the longer the better). Then you have a meniscus lens of a shorter focal length. Getting in closer will increase the tunnel effect.

    Re: Distorted lens

    Pardon the imprecise focus. It is difficult when the image field isn't flat or sharp and I'm just playing around without anyone to please.





    This with a 210 tessar. This normally focuses at the end of the track for photos 2-3 feet away.

    This was with the front half of an old Ilex Projection lens. I believe the lens is/was a petzval type, however the lens produced an image size much too small for my 8 x 10. I took the lens apart and used only the front glass and image size for this distance was easily large enough.

    Thanks, Louis. The fence does show the limited sharpness of the lens very well.

    And the image shows how pathetic Alex's swing is (I taught him all I know about baseball!), yet he got a hit and a RBI!

    No swirly bokeh, though...
