I know the general rule of thumb for minimum hand held shutter speed is the reciprocal of the lens focal length.
How does it apply to DSLRs which has "magnication factor" of say 1.5 or 1.6?
Let's say I mount a 50mm lens on a DSLR that has a "magnifcation factor" of 1.5. What should the minimum hand held shutter speed be?
Should it be 1/50 sec?
Or should it be 1/(50 x 1.5) = 1/75 sec?
Would like to hear your views and opinions please.
