I have had my 20d for over a month now, and I went shooting today and noticed after upping them to my laptop, that when there is sky in a photo, there is an awful lot of sensor dust! is it normal to get sensor dust or is that a bad thing? I used the sensor clean feature on the camera and cleaned it to my best ability, but I really need to get a can of pressurized air for next time. I got about 80-90% of it off but there is a bit there no matter how many times I try and clean it, should I have it cleaned somewhere or just get a can of air and do it myself?
Thanks,
Kevin |

| NEVER use canned air! It is about the worst thing you can do to your camera. Get a bulb blower. |

Bulb blower but not the ones with a brush on it.

Pressurised air cans have fluid in them and can cause havoc!

Dust in sensor is about as normal as dust on lens elements but probably worse.
When you cleaned your sensor, what did you do? I'm assuming you used a dust blower. I'd get a very big bulb blower and do it several times with the camera's sensor pointed down. Canon warns against using canned air blower b/c the propellent fluid may land on the senor and damage it. There are some brushes etc to clean the sensor and many have had good results with them as well. I think one is called Eclipse.
On a side note, I cringe when I see people just walking around with sensors exposed while they leisurely change lenses. I'm paranoid, when I change lens, I immediately put the plastic cap over the lensmount and then when the new lens is ready, I take it off. After each day of shooting, I always use a large bulb blower to clean out any dust. After 13K plus shots later, not one dust visible in my images.
Good luck

I didn't use any canned air, and I guess I wont, haha thanks for the info.
I just blew on it, which probably isn't good but seemed to work semi-ok.
I used a q-tip with a lens cloth on the end to kind of wipe off the sensor as well which seemed to work semi-ok as well.
I guess I'll look into getting a brush type thing for cleaning. |

I usually clean it with my tongue. First, get a 9-volt battery and touch it to your tongue briefly, to positively charge the atomic neutrons and electrons in your body. Make sure you're standing on one leg though, so you're grounded, but not creating a loop (like if you stood on two legs). Then, activate mirror lockup and lick the sensor...clean as a whistle!!!

| Canned air is fine... just DONT spray it straight into the body like an idiot.. spray it at a 90 degree angle to the body and youll not have any sensor dust problems anymore, do this to the lens and the body each time you change and youll be fine, there will nver be an instance where dust can enter the camera if each time both components are dust free when assembled. |

By blowing it you will probably have blown moisture onto the sensor which when it dries will adhere the dust to the sensor.
A mate of mine had a thick residue on his and eventually after asking on here attempted to clean it using this method

This worked fine and is now completely dust free and with regular blow outs with a good bulb with the camera sensor pointed down should do the trick.
Just dont blow on it again!! |
