The Sony Alpha NEX’s Continuous shooting modes remind me how far digital photography has brought us. The first accessory I purchased when I worked as a sports photographer some years ago was a motor drive for my film SLR. It enabled me to snap off a series of shots at a three frames-per-second rate, which came in very handy when a fullback broke through the line and headed for the end zone. Even a seasoned action photographer can miss the decisive instant when a crucial block is made, or a baseball superstar’s bat shatters and pieces of cork fly out. Continuous shooting simplifies taking a series of pictures, either to ensure that one has more or less the exact moment you want to capture or to capture a sequence that is interesting as a collection of successive images.
The Sony Alpha NEX’s “motor drive” capabilities are, in many ways, much superior to what you get with a film camera. For one thing, a motor-driven film camera can eat up film at an incredible pace, which is why many of them are used with cassettes that hold hundreds of feet of film stock. At three frames per second (typical of film cameras), a short burst of a few seconds can burn up as much as half of an ordinary 36 exposure roll of film. Digital cameras like the Alpha NEX, in contrast, have reusable “film,” so if you waste a few dozen shots on non-decisive moments, you can erase them and shoot more.
