So far, all advice on the OP's sharpness issue has to do with how to
reduce camera motion, but another factor might be involved.
Several years ago, I was photographing a highly detailed and textured
scene with an MX-EVS mounted on a Gitzo medium weight tripod with an
appropriate pan head, additionally stabilized with my camera bag
suspended from the platform, lens @ f11, shutter speed 1/250 sec. On
two successive exposures, frames #11 and 12, the first was "Rollei
sharp," that is, good as it gets, one of those negatives that
re-confirms the mystique of the marque, while the second was "okay,"
but clearly not equal to the former. That led to trials with my 3.5F,
generating similar results on 2 exposures out of 6 rolls dedicated to
the project.
Looking for answers to these anomalies is what first brought me to the
Rollei list (1997), where I subsequently learned that sometimes i20
film goes wandering in the focal plane. Why and under what
circumstances I still don't understand. Ever since, when time and
opportunity allow, I always make two exposures of a subject when I need
critical sharpness. Usually, both are good, but sometimes not.
