What Is Shutter Lag?
Shutter lag is the delay on digital cameras from when you press the shutter-release button to when the photo is taken.When you first make the switch to digital,it can throw you off a bit and lead to blurred photos and people looking away.However,both newbies and more seasoned digital shooters can overcome it with a bit of practice
and knowledge and soon you’ll be shooting as comfortably as you used to with your film camera.
With a film camera the shutter-release process is mechanical,so there is no lag beyond any auto-focusing that may happen.But with digital, your commands have to be processed by a tiny onboard computer. First the camera has to focus,then the onboard computer wipes the CCD clean of the information from the previous photo before your photo is taken.(The CCD is the digital equivalent of film.)
