Hi Guys - I'm loving my DSLR how ever I'm still looking for a good technique to change the lens.... by that I mean I am trying to keep the camera down - uncover the new lens at the back but keep that pointed down ( dust ) and the same for the old one as well as trying to get the cover on the old unit.... ( did I explain that well ? )

Basically - dust prevention..... how ever with all the above I'm finding I need more arms :lol:

Any suggestions on the best way of doing this with the maximum dust prevention....

TIA

LENS

Not lens. Pet hate.

There's no guaranteed way of preventing dust getting onto the sensor. If you're changing lenses then you WILL get dust on your sensor. I've even read that large telefoto's which extend can cause suction and move the dust around inside the camera.

I think it's just an accepted fact of digital SLR's.

PS. I unclip mine but leave it attached to the camera. Remove the bottom cover off the other lens then pick it up with left hand - with right hand unscrew the unclipped lens and have the new one at the side ready. The sensor is exposed for around a second maybe. I don't have time to spend minutes changing lenses unfortunately :(
 
Don't obsess about it, you will have too clean your camera sometime, be carefull but no matter how hard you try dirt will get in the camera.
 
Switch the camera off first to reduce the static built-up by the electrical charge. Try not to change lenses in dusty environments (or outdoors at all if you can get away with it)...

Buy a second camera-body so you can have your two most-used lenses on-camera all the time...if you can afford it.
 
You bought it to use it. The best thing about slr's is the creativity of using different lenses at different appertures etc. You're doing nothing wrong with your current method so get out there and keep shooting. Dust is a pain but not getting the shots in the way you want them is far worse.
 
Unfortunately dust is a fact of life and we have to live with it.

It it's going to be really dusty then take something to change the lens in or just use your bag as a shield, otherwise your precautions should be ok. If you're worried then take a test shot of a plain white wall or similar as this would help show if anything had got onto the sensor.
 
I get the lens to put on ready by standing it on its front cap and loosening the rear cap and making sure the index mark is in aprox the right place. I then remove the fitted lens (with its front cap on) and place it close to the next lens, swap the rear cap to it and pick up the new lens and fit it to the body. Finally, I tighten the rear cap and put the lens back in its slot in the bag, remove the new lens's front cap and turn the hood to its active position - away I go, ready to shoot. I try to keep the throat of the body facing down through the whole procedure, although plenty of dust seems to be light enough not to be affected too much by gravity. Pollen's a pain too - it's often sticky so rocket blower proof.
 
I have spare lenses fitted with two rear caps glued & screwed back to back. Remove existing lens & attach to replacement, (two lenses now joined end to end), remove replacement & attach to camera.
Doesn't directly help the dust issue but is quick.
My first post, hope it makes sense!
