Not very, if the exposure times are short or long - it is the 1/4
to 1/15th or so shutter speeds that are the most troublesome.
More important for me is the linear distortion present in virtually
all viewfinders except the Nikon "F" series (F, F2, F3, F4), which
makes accurate placement of copy materials difficult (though an
"E" screen, with cross-lines, can help). Except for flash work,
an F3 may be the best multi-purpose camera (and the ability to fit
a waist-level viewfinder in place of the prism finder is useful in
copy work). If modern fill-ratio TTL flash (with higher speed films)
is also important, it looks like the F4......
Hope This Helps
