It's not that hard to keep photo gear in excellent working condition. While regular maintenance and precautions can't prevent every failure, it's been my experience that most can be avoided with some planning and commonsense measures.
Keep your camera clean
Photographers understand the importance of keeping the inside of their camera clean to keep their camera's sensor dust-free and prevent wear and tear on moving parts. It's important to keep the outside of the camera clean, as well. When lenses are changed, dirt on the exterior of the camera and lenses can enter the camera. Keeping the outside of your camera and lenses clean will keep controls, contacts and screens clean plus prevent dirt from entering your camera.
