One of the major advantages of using a dSLR (digital single lens reflex) camera versus a EVF (electronic view finder) model is the perceived lack of shutter lag. Shutter lag is the delay between pressing the shutter release and the camera capturing the image. On a dSLR camera the shutter lag is measured in microseconds and is virtually undetectable. On an EVF camera (especially inexpensive point-and-shoot models), the delay can be over a second long. This can be especially maddening when trying to capture action shots.

When shooting today’s image of an amusement park ride I wanted to capture the train at the top of the loop. It took several attempts to to make this happen. Even though the ride’s support wires are not exactly centered, having the train lined up with them greatly improves the shot. The lack of shutter lag on my dSLR camera made this task much easier.
