1Ds - Dust Problem

[sselcer]

I cannot get rid of some dust on the sensor of my Canon 1Ds. It has been suggested that I send the camera to Canon to get it cleaned. I am willing to do that but I am concerned that this will need to be part of a regular routine – not what I expected for the price of this camera.

Does anyone have any 1Ds / dust experience they can share?

How do you know it is dust on the sensor?

Do you see it in the viewfinder, or do you see it on the finished image?

Bob,

Yes, I can see the dust on the sensor. The dust pattern also repeats itself with different lenses and is clearer at f 20.

I tried using a blower to clean it (with no luck). My camera dealer also tried to clean it.

The dust problem was there when I opened the box for the first time (actually this is the second camera with the same "out-of-the-box" problem! The first one I purchased had an even greater problem and the dealer gave me a new one).

I will admit, the humidity has been low recently, but this seems to be a real issue.

Any thoughts?

So, I understand that you've only tried to blow it off with air.

My D60 had some dust on the sensor, and I went in there with a Q-tip, which worked. Others use a Q-tip dipped in lens cleaner solution.

It is for this reason that I prefer to use zoom lenses instead of changing from one single focal length lens to another a lot.

Hiya

I have tried blowing the dust, cleaning the sensor with swabs and fluid and all this did was to move the dust to the sides and corners(which is slightly better) so now i have just recieved in the post some chamois tipped swabs that I intend to try. The chamois swabs pick up the dust rather than move it about( so I`m told) but you do still have to use the Eclipse fluid

I will post when tried

I tried a standard blower on my D30 to remove the sensor dust and nothing happened. As I don't want to use canned air I designed a megablower from a syringe, a rubber band and a large plastic bag - operated similar to a bag pipe while using the syringe (without the needle) as director of the air.

I just used whatever I had available a sunday night, but it worked. After 3 megablows most of the dust was gone!

However if dust is really stuck I recon that psysical contact with the antialiasing filter that covers the sensor using some kind of swap might be unavoidable!?!
