Jeff,

Last year, A-P introduced a new field flattener for the Traveler.  I
believe it will work with other APOs with a 2.7" focuser and 600mm f.l. 
It has a long body, about 5" and is specially designed to reduce
vignetting of the Pentax 67 to very low levels.  For 35mm you might not
be able to see any vignetting whatsoever (hence my question to Dave). 
This makes mosaicking much easier, so with a 35mm camera (e.g. with
RG200) you can more easily create mosaicked images with the same FOV (or
larger) as medium format.

If Roland ever introduces one of these for 900mm f.l., I would
absolutely buy it for the 130.  Instead, I have to spend a lot of time
doing AV, especially when doing mosiacking.
