Shut the power off and change the lens wih body of the camera facing down, change the lens and then power up. Avoid changing lenses as much as possiable!Ajay Madanhttp://www.PreciousVideoMemories.com..
I also use a blower to blow any dust off of the back glass of the lens before attaching it to the body.Chris R..
I like to hold the camera pointed to my right with the lens in my right hand parelell to the ground so that maybe the dust in the air falls between them and doesn't get trapped in the back of the lens where it will just end up in the camera eventually..
Doesn't hurt to blow the dust out of the back of the lens once in a while either..
I bought a used bellows once and did not do that. My focusing screen and mirror were so dusty after the first time I used it that I had to take my camera to the shop and get it professionally cleaned. Thank goodness it was a film camera..
I'm gonna have to sell some of this stuff so I can buy more stuff! Mummm, more stuff!..
Just be ready to do the job. that means that the new lens is already out and it's end cap loosened but still resting on top. remove the old lens, AND KEEP THE LENS MOUNT POINTING DOWN AS MUCH AS POSSIBLE. then put new lens on. then put old lens away..
The point of the switching lens procedure is to minamize the chances of dust getting into the camera lens chamber...
With today's electronic cameras, it is VERY important to make sure you turn the camera OFF before changing the lens..

That's my procedure too, and I put the new lens on the body before I put the rear end cap back onto the old lens. I figure it's easier to clean the lens than clean the inside of the body. I also position the new lens in such a way that I don't have to fiddle with itie, the alignment mark is visible and so I can just grab it and put it on the body as fast as possible..
