need some advices on the precaution to take while switching lens.

I think dust went into my camera while i was switching between lens during my last outdoor shooting, and pic turned out to be extremely disappointed when i noticed few dark spots on the exact location on many of the pic.

I tried to face the camera lens mount down while changing lens, but dust still find its way in.

any extra precaution needed plse...:cry:

There is NO way to prevent dust from going into the camera, even if you don change lens.

static generated by the sensor will attract dust. that's y the above cs member says "There is NO way to prevent dust from going into the camera."

though Olympus and Sony ultrasonic/antistatic anti-dust function on sensor may help.

Try not to change lens in dusty/windy environment :sweat:

You can don't buy the camera, then you never have to worry about this problem. :)

i ever bring in dust from body cap! I normally just throw the lens and camera cap into my bag where there is some hair ball. took the body cap with hairball inside. Close my cam with the cap and needless to say, have to send my cam for servicing. ;(

to be honest, you are better off spending money on some high quality cleaning swabs than always sending to CSC.. from what i heard, its not like they do a fantastic job..

i think not changing lens at a shoot, just cos u are scared to get dust, is a bit too much.

dust can always get rid of on PS... but u cant replicate a focal length effect say, if you dont have that lens on the camera.. the important thing, is to get the shot, and if that means having to change a lens, then change the lens.

although i cant vouch for its efficacy, some have advised that if you are going t ochange the lens, turn off the camera first. that way, it may help to reduce any static through the CCD and prevent dust sticking whilst u make the change. but no harm in doing it i guess.

one other precaution u can take, is just to make sure the camera is cleaned or dust free, before u go for a shoot.

just shoot a blue sky, or a white wall at a F/22 or thereabouts, then scan it in PS. dust spots should show up. someone mentioned about doing an auto-level as well.

Dust entering lens or body is inevitable as many had said. What you can do is to prevent changing lens in adverse dusty environment. If you need to change lens, you need to change lens, there is nothing you can do.

But, once you are in a clean environment, you can remove the lens, UV protector and check against light source whether the dust particles on lens or body senser, or focusing screen and remove them by a good lens cloth and blower-brush.
I had done that exactly last night and hope this help!:)

from the photo, seems like the dust is quite bad. I noticed a slightly longer marking there, much more bigger than a dust spot.
