Re: Horseman SW 612

[DON WHIPPLE <DCMDDW@xxxxxxxxxxxxxxxxxxxxx>]

I have a similar problem with the 4x5 Cambo Wide 47XL.
It is advertized by Calumet as a 4x5 with 15mm shifts.
I use a Horseman 612 back on it and a Helipan center filter.
Even shooting at f/32 the lens will not cover the 612 format
without shifting.  It barely covers 6x9.

Has anyone had experience with a Horseman SW612?  I have one with a
45MM Apo-Grandagon lens that produces images with substantial light fall
off.
These images occur despite the use of the ridiculously priced and
overrated Rodenstock center filter!!!  The light fall off is not
consistently strong and seems to vary, perhaps in relatiion to the angle
of the camera relative to the sun. Any
experiences would be appreciated.  The Rodenstock filter has the added
benefit of producing "outstanding" examples of flare if the rays of the
sun even feign towards the camera .
