But, Benji, francis90 wrote the OP with no mention of aperture vs. shutter priority preference, and nuff is the one of wrote about his own preference for aperture priority
Neverthelss, for the benefit of francis90, I want to explain that with meters that have shutter priority, simply take a reading and if it gives you an f/stop that you are not in favor of, simply click the up or down buttons on the shutter speed selection until you see the f/number you like to use. There is no need to retake the reading again after shutter speed reselection.
So while I like to shoot at a certain aperture, it is no difficulty for me to use a meter with shutter priority.
I am perfectly aware of this, but at the risk of stating the obvious apertures are infinitely variable shutter speeds are not.
