The speed of the camera body is measured in frames per second (fps), and determines how many photos you can take in one second. Remember that delay with your point-and-shoot camera? No more! Some digital SLRs are faster than others, and if you are shooting sports and action photography, then speed is what you need. Most SLRs start at around 3fps, which should be fast enough for most beginners, especially if you’re shooting portraits or landscapes. If you need faster, jumping up to a camera with 6.5fps (like the Canon 40D) may be a worthy investment. Remember, these faster speeds will cost you, so make sure that you identify whether or not you really need the extra speed. Unless you are shooting sports, weddings, or action, 3.5fps should suffice.
