Voorbeeldje:
When shooting EOS Movie footage with the EOS DSLRs that offer EOS Movie capabilities (the EOS-1D Mark IV, EOS 5D Mark II, EOS 7D, and EOS 550D), the accepted rule of thumb is to use a shutter speed that is twice the selected frame rate. For example, if you were shooting at 25fps, your shutter speed would be 1/50sec. However, you will notice there is an issue if you choose 24fps. Since there is no 1/48sec shutter speed setting, 1/50sec is used instead. But if you switch the camera into half-stop exposure increments using the Custom Functions, you will find access to a 1/45sec shutter speed setting. This isn't necessarily any closer than 1/50sec but it can prove useful in situations where you need to use a slightly slower shutter speed to capture more light to achieve the perfect exposure.

Dust busting trick
Dust is a perennial problem for digital photographers, which is why Canon implemented the EOS Integrated Cleaning System (EICS) across the EOS DSLR range. However, you can help in the fight against dust too. When you remove the camera body cap and rear lens cap from your kit, don't just throw them in your bag or stuff them in a pocket. The two parts fit perfectly together and lock as one unit. If you fit them together not only will you avoid collecting dust in the caps, that could later make its way into your camera, but you'll also only have one item to look for in your kitbag, not two.
