Dust on sensor?
"phk" wrote in message
oups.com... I've been reluctant to switch to DSLR because of the potential problems with dirty sensors caused by the ability to remove the lens. Is this a real problem with DSLRs, or not as bad as it seems. It appears that Canon recommends use of a hand-held blower for dust removal, but I wonder whether that actually works. Dust is often tenacious and bonds itself to surfaces in ways that are resistant to simple blowing. Maybe the best example is my eyeglasses. Once they get dusty, only windex will clean them thoroughly. Dust on a sensor is not a huge problem but it is a problem. I clean my sensor with a nylon makeup brush, only costs about $ 10.00 as oppossed to about tentimes that much for a nylon brush from VisibleDust. A blast of compressed air gives the brush a static charge and then I wipe it across the sensor and it lifts the dust off. |

The sensor won't be subjected to that humidity and so the dust should bind less to its surface. |

This dust elimination market is really a scam, which is no suprise in the photo market. Methanol based cleaners at $10+ for about $0.10 worth of alcohol. Specilized q-tips at $40-$50/pack. People should realize that the front of a sensor is the same as a lens and you don't have to be hyper-paranoid about it's treatment, just cautious. Blow off what you can, then use a brush and finally, clean it with fluid if it needs it. Do not use circular or long strokes so you don't accidentally drag any grit across the entire surface. Much of the dust in the air is sand, or quartz-based and harder than glass or coatings and can scratch them. -Rich |

Dust is often tenacious and bonds itself to surfaces in ways that are resistant to simple blowing. Maybe the best example is my eyeglasses. Once they get dusty, only windex will clean them thoroughly. Forget your glasses. They are always in the open and pick up a lot of moisture from your eyes. I use a large hand blower first, and if that doesn't work I use a Pec Pad and Eclipse. Just follow the directions you'll find on the Net, don't be afraid, and you'll find you can clean the sensor (or actually the filter) in just a few minutes after some practice. Brushes never worked for me, but some people swear by them. Don't let the dust problem keep you from getting a DSLR. It's not that big a deal. |

OK, I know this is bad, but I use a high pressure air aerosol. Have done so
on more than 20 occasions. No problems yet. "phk" wrote in message oups.com...

I've got all the specialized expensive stuff, but...with one or two exceptions, my sensor cleaning has all been done with a brush. Spending $100 for a brush is, IMO, insane. Get a make up brush of the appropriate size, wash and rinse at least twice in distilled water and dry in a dust free environment. Store in a clean plastic bag. When clean-up time comes, spray the brush fibers with canned air to create a static charge. Then stroke down or across the filter covering the sensor. 999 times out of 1000 that does it. If I change lenses in poor conditions a lot, I might have to do my sensor cleaning job every week or two. If not, a month or six weeks, and sometimes two months or more, go by without a need to clean things up. This is really a non-issue that continually gets promoted to problem status. Anyone who doesn't have 10 minutes a month to check and care for SLR gear probably shouldn't buy the SLR. |
