P3D Re: Wollensak Lens Boards FS on S3D

Since discussions are discouraged on S3D, I have moved this
here. "hear2see2@xxxxxxx" posted some Wollensak lens
boards for sale on S3D with the suggestion that they could
be used to upgrade a Revere from f3.5 lenses to f2.7 lenses.
I would like to caution that this is not as easy as it
sounds. The distance from the lens board mount to the
film plane is less in the Wollensak than in the Revere.
The body or the film guide will need to be machined to
reduce this distance. This difference is well beyond
the range of the adjustment screws. Making this change
is not practical without the use of a milling machine.
The camera will then need to be re-collimated.
I have gone through this on mine, but I still haven't
put it back together and tested it. It is a lot of work
for an extra half an f-stop, considering I rarely shoot
at anything wider than f5.6 for reasons of depth of field.
