Dust Prevention

[Cuban]

A basic but important 'newbie' question.

As I'll be adding a 55-200mm to the 18-55, so what steps should I take to ensure I remain
dust free when changing them over?

I will be working in a lot of dusty environments, so naturally will try to only change over
in a room or a car, but are things like a Rocket Blower a wise investment?

Anything else I should grab while I am at it?

ALWAYS point the camera body to the ground when changing.

A rocket blower is the only cleaning tool I've needed, and I've never needed to go any closer than a couple of inches away from the sensor. I'll only think about buying anything else if I actually need it due to a stubborn object.

I do make sure that I never change lenses in a windy place though but other than that I've been OK. I haven't found dust very often, I suspect on the times I have had some spots its been because I was being lazy and holding the camera facing upwards.

Turn off the camera before removing the lens

Thanks for that guys, Rocket Blower it is then and I'll be adding a Lowepro Slingshot 100AW bag.
