Is the other part of that rule of thumb that you set the exposure time
for 1/the lens length? I.e., if you're using a 75mm lens, set the
exposure time 1/75 (or as close as you can get).



While not affecting actual exposure, this is a good rule to follow to avoid
camera shake with telephoto lenses-use the focal length as your slowest
shutter speed.

True.
