Lens changing when out and about

I have to admit that I'm a bit paranoid about switching lenses when out doors, the concern is 'dust' and 'dirt' getting in and contaminating the exposed sensor. I've read around the topic and various individuals have a variety of strategies, such as camera tilted down, back to the wind and super fast switching with lens caps glued back to back etc.
Any tips, any horror stories to put me off changing short of a clean-room

Re: Lens changing when out and about

hi Ricoh,
its not a problem to switch lenses outdoors. I do it all the time and had never any problem. Just switch first your camera off, then take out the appropriate lens, switch them with your back to the wind if possible n the mount pointed downwards. switch your camera back on when u attached the lens you need and let the "dust shaker" do its job. Works every time.
If you are really afraid that dust has affected your sensor, you can always let your sensor be cleaned by a specialist company or at a photo shop. I always go to: http://www.chipclean.nl/content/view/13/27/lang,nl/ They do a very good job, are cheap n give garanty on the cleaning. They can do it cheaper and better then Olympus
Hope i could help you.

Re: Lens changing when out and about

One of advantages of E cameras is a rather good dust reduction system. Also there is apparently a rather thick piece of glass in front of actual sensor that amongst other things helps to reduce the effect of dust.

Apart from changing lenses reasonably quickly or putting body cap on and pointing camera down there is not much else you need to do.

Re: Lens changing when out and about

I just do it as quickly as I can. I give the incoming lens a quick blow but that's all and never had a dust problem in 8 years of owning e-system cameras.

Same here. Back to the wind and quick swap. I prefer to do it in the shade rather than direct sunlight, in case I fog the sensor ..

Re: Lens changing when out and about

Never had a problem with E System despite changing lenses in a Desert, at altitude etc the SSWF(?) seems to have taken care of it so far.

That's why I always use a changing bag when swapping memory cards and insist upon a hand search of my cards at airports rather than pass them through the scanner along with the rest of my luggage. I believe that this is particularly important if the cards have been exposed at high ASA.

Re: Lens changing when out and about

I've had no problems with any of my Oly digicams and dust. The SSWF thing does its job !

My Sigma bodies, however, have taught me how to clean a sensor. Regularly. "Dust magnets" are Sigma bodies :-(

Re: Lens changing when out and about

I have a mate who has a camera made by a well know photocopier manufacturer, he is paranoid about this and convinced I am lying when I say it's not a worry for me
Mind you I also take a bit of care like most folks have suggested

Yes, back to wind ; lens down when you remove and fix Even my E-1s and E-5 I did not have a problem with no do I as I still use them

Now horror stories are more experienced with anikon

Good point - esp with mirrorless ad I have learned "Sun" causes great damage

Re: Lens changing when out and about

A bigger risk is changing lenses and dropping your new 300mm f/2.8 and having to wipe the mud off the front element with your T shirt. Not me I must add, I've done much worse in my film shooting years.

Re: Lens changing when out and about

Ok, I see a convergence here, that being quick and shielding from the wind.
I'm not sure whether I'd be comfortable changing in a sandpit, that takes courage in my mind!
According to Wikipedia:
"The Supersonic Wave Filter consists of a very thin piece of filter glass placed in front of the image sensor. The area between the filter and the sensor is sealed, so no dust can enter. Whenever the camera is turned on, a piezoelectric driver induces a vibration in the filter glass, shaking dust off. A piece of adhesive located inside the camera traps removed dust."
Is this true of E-System cameras? Sounds like a good idea, otherwise the sonic wave thing is merely dispersing the dust, and the dust will settle anywhere it can, including mechanisms and the sensor glass. A replaceable service item, the adhesive [strip] sounds brilliant.
