Do you want sharper photos?  Then increase your shutter speed.  A slow shutter speed is susceptible, camera shake, subject movement, motion from wind.  So if you are shooting at 1/50 - 1/250 second shutter speeds, try to get faster than 1/500.

Faster shutter speeds improve sharpness in photos.  Try increasing your shutter speed to get that shaper photo the next time you are out shooting.
