Shutter lag is the delay time between pressing the shutter button on
your digital camera and the interval you wait until the photograph is
actually taken. Most of this delay time is taken up by the camera
focusing on the subject, exposure calculation and the
electronic or physical shutter
We all hate this when it happens. You spot a great photo opportunity and
turn on your digital camera. But by the time it's ready to shoot, the
moment has passed, lost forever. Or worse, it is something that you can
never capture again, as can so often happen when taking pictures of your
children. With modern digital SLR cameras, an advanced closed-loop
control circuit allows a fast estimate of appropriate focus distance,
without having to slowly move the lens back and forth. Hence, the
picture capture time is greatly improved and almost instant.
Slow start-up and shutter lag plague many compact digital cameras.
Although camera makers improve responsiveness with each new model, most
digital cameras are slower to respond than their earlier film
The Latest designs have reduced this problem since the early digital
Tips that can help
you to decrease 'shutter lag'.
Pre-Focus or Pan your camera to overcome Shutter Lag, or Use the Manual
The great thing about most DSLR cameras is that they allow you to turn
the auto focus system off and focus manually. With a little practice,
you can keep a moving subject in perfect focus while panning to keep
your subject framed in the viewfinder. Switching to manual focus
eliminates shutter lag caused by the auto focus system when you trip the
If you want to fully disperse with shutter lag then swap your compact
camera for a digital SLR? Then now's the time, because the range and
quality of DSLR's on the market has never been better. Compacts are fine
for casual photography, but they have limitations which quickly become
apparent if you decide to get serious about taking pictures.
DSLRs can look complicated at first, but they all have fully automatic
modes for the less experienced, and the least expensive models are
designed specifically for people moving up from a compact.
Finally, selecting a Camera is more important, because this could be a
long-term decision. You can buy extra lenses for any camera, but they
will only work on a particular make. Currently Canon and Nikon have
excellent DSLRs with intrinsically low shutter lag and the widest lens
ranges, although other companies are catching up.
