Here's how: 1  Stand with your feet shoulder-width apart and knees bent slightly. 2  Lean forward, placing your hands just above your knees. 3  Round your back so that your chest is closed and your shoulders are curved forward.  Then arch your back so that your chest opens and your shoulders roll 1  back. Repeat several times.
Typically this count is between 100,000 and 300,000 shutter actuations, with the latter limit associated with the EOS-1D models. In fact, the Camera Shutter Life Expectancy Database is a really neat user-based site for DSLR models of several brands, including Canon.
Frame rate refers to the number of individual frames that comprise each second of video you record, also known as FPS (frames per second.) The most common frame rates in video are 24, 25 and 30 frames per second. Shutter speed refers to the amount of time that each individual frame is exposed for.
