So Cannon Girl has become Coffee House Girl.
The main purpose for this image is to see what I can do with my Vemer 12mm f8 fish-eye.
First I'll describe the lens, it's a solidly built early 1970's ultrawide. T-mount, which means
that you lose nothing in operation when using it on the *ist-D. Program, Tv and Manual modes
all work as expected. This is designed for use on a 35mm camera as a semi-circular fisheye
which makes it a full frame fisheye on an APS sensor.

This is a surprisingly good lens, it is however no SMC-P 17mm Fisheye. Nothing is exactly sharp, the
lens depends on DOF for focus, there is no focusing helical, and at f8, it's widest aperture, as you can see
even in the reduced size photo for the web only the center portion of the frame really looks in focus. There
is also a pronounced color fringing that becomes worse the further from the center of the frame you look. I'm
not sure if this comes from chromatic aberration of from poor color correction. Still this lens and it's sisters,
(made by Sigma and sold under a number of different names, from the mid 1960's to mid 1970's), seem to be the
only full frame fisheye solutions available to those of us shooting the *ist-D and maybe even the Canon and Nikon
APS frame digitals.

As usual comments are welcome but may be totally ignored.
