How to clean Sony DSC-W7 sensor?
I have an old Sony Cybershot DSC-W7 at home, that I still use. It's not a great camera, but I keep it for use instead of my other cameras because I have the Sony underwater housing for it, so it comes in handy at the beach, trekking through the (rainy) forests near Sao Paulo, and for scuba-diving.
Recently, a small dust particle got lodged on the sensor. I think it's actually on the anti-aliasing/IR filter assembly, because it almost disappears with the lens wide and f/2.8, but gets very defined and visible as a large black spot when I zoom in and close the aperture.
Is there a way to open the camera and blow it away, at home without special tools, while being able to close it back up to working order later? If it wasn't for the excellent underwater housing, I'd have ditched this camera long ago, but since while I don't buy a housing for my Olympus E-PL5, I'd really like to salvage the Sony, since it's got a good jpg quality for a compact!
Thanks in advance,
