I've been fooling around with a little math trying to
figure out the focal length equivalents from 4x5 to
35mm. Maybe I'm doing it totally wrong, but I come up
with about 210mm being the LF equivalent to a 50mm
lens in 35mm format. Is there a quick & dirty formula
or maybe a chart that gives approximate focal length
equivalents between different formats?
