Realist 3.5 vignetting and accessories

[P3D Mike Sherer <mikesher@xxxxxxxxxxxxx>]

At last Wednesday's Detroit Stereo Meeting, I witnessed
the unveiling of Dr. T's 7p Realist, customized by John
Slivon, and asked him about the differences about the 2.8
and 3.5 Realists, chiefly the lenses and shutters, and
George said that the 3.5 lens, although sharp, has light
fall off at the corners (vignetting) at the small apertures
f16 and f22.  My 3.5 has no light fall that I can detect,
and it constantly hovers over a tripod on f16 and f22.

In a very recent post, Grant Campos said he was having light
fall off at only f11.  Now I know that every lens is not made
identically, but what can explain such a discrepancy.
By the way my lenses are the ordinary David White
Antistigmats.

Also, where can I find a cable release and a filter holder
for the Realist 3.5? Can a Cokin system be adapted?
