Yes, not precise at all on the Speed. Not because focus is critical
with a 65 on this format; it is not. Scale focus is more than
adequate. The problem is that the inside rails do not allow for
precision alignment of the lens standard, and finding the parallel
point is uncertain guesswork.

The Busch Pressman C, however, has a much superior mechanism for the
standard to ride this inner rail. Parallelism is assured, the action
is smooth, and there is plenty of room for a focus scale and DOF
markings. Furthermore, it is mush easier to drop the front cover out
of the way to shoot with such wide lenses...
