Why you should be careful with DSLR dust ...

Here I thought facing a DSLR down, keeping the unit off and not being outside in a windy area while changing a lens was just a guideline for people who are too pedantic in their habits. How wrong I was.

I've had my 450D for just over a week now and managed to collect a heap of dust and (somehow!) sand on the viewfinder and unfortunately all over the sensor LPF glass. Air blower didn't work so I had to drive down to Canon for a 5 minute cleaning job which turned out perfect. Free first time round since I just bought it, $50 for future visits.

Before and after cleaning pics with f/22-36 (clicking recommended for hi-res):

Well it does that automatically when I turn on/off the camera, even invoking it manually and also holding the mirror up to blow dust in by blower bulb had no effect. The blower actually made it worse :/

To be honest if they can get it perfectly clean like they did today, I wouldn't mind taking it in once or twice a year at that price. I went from not being able to do anything over f/8 to being able to do f/36 perfectly.

I'm usually a DIY kind of person (I like tinkering), but not with brand new / relatively expensive optics! I have a habit of making things worse.
