Test using dust-aid sensor cleaner
At Birmingham's NEC event (see recent post) I bought some Dust-Aid DSLR camera sensor cleaner. Today I tried it out on my Pentax's K10d and istD and on my Canon EOS5d. The latter came from Canon with a dirty sensor that did not respond to my blower brush - I don't have to change lenses on this camera so it's foing to be interesting to see what happens.
I had to use a special Canon Cleaner lower tack pad on the Eos5D and the Pentax K10d. I used the same pad to do both. I used the standard pad on the Pentax istD.
This is the Canon EOS5d before...
Sorry, the sky had changed! Still, a dramatic improvement with just one or two smaller marks remaining.
Here's the Pentax istD before (note bottom left)
Still some specks remaining but the biggy has gone.
On the Pentax K10D the change was more subtle so I'm not reproducing the results.
At Birmingham the guy who sold me the Dust Aid said that greasier dust could remain and you needed to use Eclipse to remove that. We can see thta in the above. And the K10D with its self cleaning sensor would be expected to expel looser dust so maybe that is what happened here - what was left on the sensor was the trickier dust spots anyway.

So at least now I have three relatively clean sensors. I'm particularly pleased with the Canon which had not responded to the blower brush. But will it stay clean, even though I will not be removing the lens? I've read elsewhere about manufacturing debris in some EOS5d's causing all sorts of problems. Hopefully I have a clean one now.
