Your handy air blower is still the most effective and readily available dust removing tool for your DSLR image sensor. Don’t fall for built-in dust removal “technologies†touted by marketing hype; they’re just hot air.
PixInfo.com recently ran a real-world test on four DSLRs that advertise dust removal or dust reduction techniques: Canon EOS-400D, Olympus E-300, Pentax K10D and the Sony Alpha-100.
The result was utterly disappointing. The best performer turned out to be the Olympus E-300, but even this came up only with an unsatisfying 50 percent dust removal. All the rest? Zip. Zero. Nada, as in, “Hey, did you advertise dust removal? There’s nothing here.â€
So don’t throw away that good old air blower just yet. You will still be using that a lot. Then, when dust really becomes recalcitrant, use chemical cleaning (99% clean ethyl alcohol) or some other sensor cleaners now in the market. And read up on how to do that starting with this article here.
