Though I use mirror lockup, the focal plane shutter makes a serious
thrust and
speeds lower than 1/60 show it. Hand dampering the camera helps, but
even that gets risky the slower you go.


I don't know the absolute lightest you could get away with but I use a Bogen
3221 and an Arca Swiss B1 head which is a pretty light set up. My primary
formats these days are 4x5 and 8x10 and there's no noticeable difference
between 11x14 prints from them and from the 67 (I don't use the 3221 with
those formats).

I've been using a Pentax 67 for about 10 years, almost always at speeds of
1/60 or shorter, and never had any problems with the shutter affecting the
print, at least not anything noticeable with prints of 11x14 which is the
largest size prints I make from 6x7 negatives. At what size prints to you
notice this deterioration in quality with speeds slower than 1/60?

I'm hitting the road in the Spring, backpacking, and am considering
using my Pentax 6x7 exclusively.

What do think is the lightest tripod I can get away with using slow
speeds?

I've been using my heavier Berlbach with a sizable Bogen head around
home areas, as my lighter Bogen made for some very unsharp tests, but
I can't see
taking it on a long backpacking tourism trip.
