Sensors & dust

[GrumpyOne]

How big a problem is sensor dust in a dusty, polluted environment? If you were living in a dusty area with a lot of air pollution and particulates, would some sort of automatic sensor cleaner become a desirable feature?

In theory, yes. However, now that several manufacturers have had anti-dust systems out for a while, they aren't getting great reviews. It sounds like the help, but they don't come anywhere near eliminating the problem. I wouldn't worry (for sensor issues) about the air pollution unless it is particulates; ground level ozone isn't going to stick to your sensor.

Invest in a good sensor cleaning kit with a static charging brush, a gentle scrubbing solution, and a sticky pad solution. Once you get some practice (and you will), it only takes a couple of minutes to do a thorough job. The best time to do it is shortly after a shower in a well ventilated bathroom. Let the moisture in the air pick up all the dust particles but don't do it while it's so damp that you have to worry about condensation.

You'd be better served with a rocket blower and a sensor swiping kit. I use the rocket blower every few weeks and it gets my sensor about 98% clear of dust. Every few months or maybe 2 times a year depending on bad things get I'll do a sensor swipe with the kit from copperhillimages.com

Dust on the sensor of todays dSLR's is a fact. The in camera technology of dust removing isn't very effective. Rocket blowing is very easy and does a very good jog. Sensor swiping is even better and one you get the hang of it will probably be just about 100% effective.

Like they said.

Sensor-based dust cleaning is certainly not a bad option to have, but you'll still have to go in there with a Rocker Blower and sometimes even with a complete sensor cleaning solution, which are not as scary as they sound and not very expensive if you go the pec-pad plus wand solution.
