We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
It's good to be aware of the problem. I always keep the body turned down when I change the lens. If you're in a very dusty environment a clear plastic bag can be used to facilitate the switch. I'm not sure that would work for people like James Natchwey, who might be in too much of a rush to swap out a lens, but for mere mortals it works quite well.
If you're not stopping down the lens for a greater depth of field (or shooting at hyperfocal distance), dust is much less of an issue as the offending mote is often washed away in the circles of confusion. (It's outta' focus).
I got my hopes up when I saw the link as I just got cool nikon 70=200 lens but can't use it properly w dust on sensor. EVIL SPOT Who knew, back in easy portable point and shoot days how much maintenance these monstrous cameras take! Kids tease "Mom: it's God's way of telling you to keep a cleaner house, and stop hiking over the river and thru the woods when you could be dusting like a good little Stepford wife!" Me gnashing my teeth until I can get the sensor cleaned by a place that will do it onsite (the chicken mini blaster thingey didn't work)
Only long term solution is to get another camera and keep the 50 f 1.8 or 60 f2,8 on one all the time and the zoom on the other. And clank as I hike and have kids pretend they dont know me...but the occasional captured critter or awesome light makes the hassle worth it
Heh, retriever you're funny. I use a Giottos Rocket as well, which works perfectly. I shoot a D2Hs, which allows mirror lock-up with a de-charged sensor to loosen up clinging dust motes. But I'm assuming your chicken mini blaster thingey is on a par with the Rocket.
Here's a helpful link (if you're intrepid):
