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.
