| I am curious...don't all DSLR's have a filter over the sensor like my D70? Or at least you guys with the 10D, 20D, 300D cameras, etc? Or are you actually getting right down onto your sensor when you clean? If that was the case, I'd probably not risk the tape method, myself, simply because I would be so paranoid. |

Nikons, Canons, etc all have covers over the sensor. When people talk about cleaning the sensor, they're really talking about the glass OVER the CCD/CMOS.
However, if you scrath that cover, you're still going to need factory repair which probably involved replacement of that entire component, so it's effectively one in the same.

Much of the time you'll blast if off the sensor sucessfully, but you may be moving it into other parts of the chamber where it can fall back onto the sensor from. There is also a high risk of tipping the can the wrong way and shooting toxic goo onto the sensor that requires a liquid to remove.
If you're always hyper-careful, and a little bit lucky, compressed air will work. |
Agreed that it is a sledgehammer - air stream is powerful. But no goo - it is just compressed co2. No tipping of can - this is compressed co2 in a cylinder, which screws into the bottom of a nozzle. No luck - brute force. Definitely works!
Will have to buy more cannisters over time, making for additional cost (I think that they are about £1 each). I have played with mine putting out candles and stuff as well as vigorous sensor clean, and it is not dying out at all.
Shop selling them was pretty professional: guy next to me was picking up two lenses that each required a suitcase to carry...! Was their only recommendation.
Here is a link to their US site - $22 for kit, and $9 for six replacement cannisters. |

I just went to the site to look at this and it had just one review. See it here:
Review of CO2 kit
It seems like a good idea, but I'd hate to risk ruining something.

What's that magic tape from 3M? where can be bought?
Today I tried to clan my sensor with a blower. It's not a very potent one but it works. I panniked when I came home last weekend after a nature photo session and realized that some photos had some major points showing that wheren't supposed to be there! So I'm getting courage to do a deeper clean but I'm not shure what to use. This tape seems simple and vurtually impossible (if you are gentle) to risck the sensor.
Onlu one more question: any decent, reliable site in europe to buy items to clean the sensor?

Know they have to include in the features sensor cleaning :)

Bom dia, Nuno. You should be able to pick up this tape from any office supply store. If they don't stock it, they can most likely order it. I would be blown away if you cannot find it somewhere in your city. Unless you live in the mountains or something. :) |

I live in the mountains and I found it - in the works stationery cupboard :)

D20 and Lock-up. Haven't had my 20 long enough to figure out how to lock it up. Can someone save me the time give me a quick how-to on the lock up procedure. Everything on the 20 is pretty well laid out so I am sure it is easy to do ... just haven't needed it yet.
Thanks

My DSLR disassembles for cleaning which makes access to sensor nice. But the camera is still susceptible to dust, which is plentiful here in the desert southwest. I use a compressed air duster at a distance of about 10 inches from the camera body and the digital back assembly, and then clean the sensor with an alcohol moistened gauze pad. I inspect the surface carefully under strong light to insure there are no smudges or streaks on the glass. Sometimes a dry pad will remove residues from moist cleaning. Then gently reassemble taking care to not stir up any ambient dust! Would be nice to have a 'clean bench' for this process.

| I did it!, well, not me, only my wife was relaxed enough to do the process. After the process some dust spots dissapeared but there are a few in the top left corner of the image. ¿Where are they over the sensor?, ¿Over the bottom right corner?. Thanks to Rebelo for this amazing technique. |
