Changing lens on-the-move
Assuming wearing photog vest capable of holding lens. Can I know how you change lenses with an aim of minimising exposure of the mount to dust?

1) unmount lens with left hand
2) slowly open bag with right hand, let camera hang by my side
3) find rear lenscap
4) talk c**k sing song with friends
5) mount rear lens cap
6) put lens into bag
7) find 2nd lens
8) slowly unmount rear lens cap
9) find the dots on the cam and lens
10) slowly mount new lens
no problem with dust, even at beach

Back on topic for yaoxing ... I agree with Witness, that's what I do as well. All you can do is minimize exposure to the elements, and try not to change lenses if you can. If dust is being kicked up all around you, look for a "safe" environment to do this in, eg. the vehicle you came in, a nearby shelter, etc.

I try not to do it standing.
My stuff is usually in a minitrekker. Take off the minitrekker, put it on the floor, unzip it.
Take the lens off the camera, slip it into an empty compartment, with the rear end sticking up.
Quickly unscrew the rear cap from the lens I want to change to, and screw that onto the lens I have just taken off.
Take the new lens and mount it on the camera.
Zip up the bag, put it on my back.
You'd be surprised how fast all this can be achieved. And no danger of dropping a lens on the floor - isn't that worth a few extra seconds?
Sorry if the instructions sound a bit obscene (after I have re-read them). To the pure, all things are pure.

Turn off the power switch when you change len, as electric charge will cause dust to collect on the CCD.

Switch first, worry about dust later. Getting the shot is more impt
