This brings up some questions I have, since I am fairly sure I
answered this post some time ago: Why do threads often seem to go on endlessly, often with repetitions of the same answers? Do some people not receive some posts during the time they are available? (Do they disappear before some people have had a chance to read them?) Some
peoples' posts seem to remain a long time, and others' posts disappear
in a relatively short time - is this true? It sure complicates
communications if we are not all enmeshed within the same time frame...

Back to the original question: the PB-6 does not have tilt-shift
capability, but the Nikon PB-4 does, and works very well out to
infinity with lenses of about 105mm to 150mm. Enlarging lenses
can often be adapted using the BR-2 ring to provide the Nikon
bayonet (strong skylight filters may be needed to approximate
the Nikkor lens color balance).
Hope This Helps
