D-100 and dust!!

[scubapauly]

I'm using a D-100 at the moment and it seems to have some dust either on the CCD or the mirror. I've changed lenses and the marks stay with the camera. I've taken the lens off and given the inside of the camera a good blow with compressed air, also tried with the mirror up but no difference.

Any more ideas????

There's a wealth of information on the internet about sensor cleaning, Paul - even BF has a lot of helpful stuff.

Personally, I wouldn't go near the inside of my camera with tinned compressed air. OK in theory, but it's essential that you keep the aerosol completely level to ensure you don't splatter the innards of the camera with liquid propellant.

A Giotto Rocket blower is a much better idea, IMHO. Hold the camera upside down with the lens off and the mirror up and give it a few squirts, and you might shift the offending muck.

If that doesn't work, I'd suggest the Copperhill Sensor Sweep brush - it works really well to dislodge muck that isn't stuck to the sensor, using static electricity to lift the dust.

Failing that, you're into Pec-pad/spatula/Eclipse fluid territory - "wet" cleaning - but it's straightforward enough if you follow the instructions.

Agree with everything Keith says but would emphasis DON'T blast compressed air inside the camera body! Even with the can level it could force grit that hard against the sensor it could scratch it.

I cleaned my sensor for the first time this morning using Sensor Clean followed by a statically charged Brush and its worked perfectly. I also used a brush on the focussing screen which had attracted its own collection of crud

All I've got to do now is clean the brush which I nearly dropped, caught clumsily, just brushed with my finger and which has now got grease on it. Great! :C

Thanks for the tips, time for some more reading.

I concur with what has previously been suggested too.

I use a Giottos rocket to shift most dust but if that still doesn't do the trick I use the Copperhil wet method of Pec-Pads and Eclipse. I managed to source some sensorwands from Germany nad have 1 left if you are interested? £4.99 incl P&P

PM me if you want it.

Cheers

It works!

I would check out these http://www.birdsasart.com/lenspens.htm You can buy them in Jessops or in Warehouse Express(Under brand Hama) They are brilliant and are used by Canon in their repair centres. Art Morris has very good instructions on how to use them and it is quite important to read his instructions.
