Equipment Handling and Maintain Guide

Note: DSLR camera is not compact camera, as when you interchange lens, dust can come in, so

keep you DSLR equipment in a safe, dry, good air flow environment, as in wet environment, Fungus can grow into the equipment, (which is bad)
when interchange lens, make sure camera open mount is facing down, so no dust drop in,
- blow away dust when lens is mount up while mount part face up.
- then mount it.
camera bag should be clean and soft and safe.
get a dry box if possible, but as long as you use it every day, shine them under the sun, they will be healthy and fresh

I have met Fungus with my first lens, it is in the corner, but as I use this lens most time, it didn't grow, and my APS-C doesn't not see this full frame lens corner;
- the technical term for lens opener is: “Spanner Wrench” (双头工（井）字扳手)
Home lens clean solution:

I have met Dust in Camera Sensor, I blow it away almost completely with Giottos Rocket Blower in Clean Toilet, only one tiny dot showing up with small aperture below f8;
