Do I need the motordrive to shoot sports photography?
To guarantee success, try switching your DSLR’s Drive Mode to Continuous Shooting. Your DSLR can typically shoot a motordrive sequence at a rate of at least 3fps.
Most sports photography pros use this setting, because a choice of slightly different compositions can help to capture a better expression on an athlete’s face, or to capture a dramatic moment.
But you can still miss the moment when shooting a rapid-fire sequence. If you use a shutter speed of 1/1000 sec, even with the top-speed 10fps burst mode of a Canon EOS-1D Mark III, for instance, you’ll only be capturing 1% of what is actually happening – 99% of the action is unseen by the camera!
The other disadvantage is that most DSLRs can only shoot in top Continuous mode for a limited number of shots. Beyond this, the camera literally stops and catches up with processing and writing the shots to the memory card.
This buffer limit is reached sooner if you shoot in RAW (or RAW+ ), so most photographers wanting to make use of Continuous drive mode will switch to JPEG. Do this with a camera like the Canon EOS 400D, for instance, and you can shoot at 3fps for a full 9 seconds (rather than 3 seconds if you shoot in RAW).
If you want to know how many shots you have left before the buffer memory fills up, just look at the number on the bottom right of the viewfinder. This tells you how many shots you have left before the camera needs to stop.
However, when using an SLR’s motordrive there’s a danger that your camera will stop shooting just as the real action begins – so always use this facility with caution.
