Digital Advent Calendar 2010 - Day 8

Changing Lenses

When you’re changing lenses on a digital SLR care needs to be taken so that dust doesn’t get inside the camera body which can find its way onto your camera sensor.  Dust on your camera sensor will result in spots appearing on your photographs which can only be removed by using specialist equipment.

To minimise the chance of this happening ensure you’re in a dust free environment and that your camera body is facing down when replacing your lens.  It is good practice to put both the front and rear lens caps on the lens you’ve just taken off to protect them fully.
