So you can consistently handhold 1/30 sec with a 50mm lens? |
Many people say yes, and they may be better at it than others, but technically speaking, no. Your body isn't still for that long. |
The 1/focal length rule is for 8x10 sized photos, and assumes that a given sized circle of confusion is acceptable to the viewer. If you can live with a larger CoC (ie more blur) or you are shooting for 4x6 or the web, you can handhold longer.
Also, individuals differ. Some can handhold longer than others. Some people cannot hold a heavy lens steady at all.
And there is a fuzzy area where at a given speed, you will get some but not all of your shots acceptable.
So as a guess (I'm too lazy to do the math) if 1/80 is the speed the rule gives for a 50mm lens on a 1.6 crop camera, then you could take a 4x6 at 1/40 (4 inches is half of 8 inches). With the right technique, its possible someone can handhold at 1/30 and get a good shot. |
