Photographers mainly use multiple lenses to produce different photo results with 35-millimeter film and digital SLR cameras. This requires frequent lens swapping while shooting photos. Replacing a camera lens on your camera tends to be a fairly easy task if you follow the instructions for your particular camera. Following the correct steps will not only protect your camera, but it will also ensure you don’t get foreign particles inside your expensive lenses.
5 Always keep your lenses in a camera bag and your camera strapped to your neck when making lens changes in the field or outside. This will prevent you from accidentally dropping and damaging a lens or your camera.When changing the lens on a film camera, do so under a coat or in the shade, if no cover is available. Otherwise, the sun and light will enter the camera body as you change the lens and may damage photos.
Take the lens you removed and place the front lens cap if missing. Place the rear lens cap from the replacement lens on the back of the removed lens. Put the removed lens in your camera bag, in a lens case or in safe location in your office or home. Make sure it doesn't sit were it can be knocked over or dropped.
