Thought I had `cleared` the sensor on my 30D Mark but not quite and I am not sure what to do next, I am loath to mess any further.

ReplyDelete2 options are dry or wet clean - dry cleaning is something you should probably look to do regularly with something like an Arctic Butterfly (probably also need a sensor loupe as well). Dry cleaning will pick up the bits of rubbish with a static-charged brush.
Wet clean, where you have spots on the sensor glass, is a bit more of a tricky operation using pads dampened with a cleaning fluid.
As ever very easy to get all of this wrong so if not confident take it into a camera shop and they should be able to do it for you - tho make sure in your case they do both a dry clean of the chamber and wet clean of the sensor
Unfortunately every time you change a lens you run the risk of introducing contamination into the sensor chamber - if you look closely you'll probably find all sorts of weird bits of dust in the camera when you take a lens off. Also useful tip when you change a lens or clean the chamber/sensor is to do it with the camera facing down
Sorry alternative of course is to clone the dust spots out in post-processing although sooner or later you'll end up with a spot in a place you can't do much about!
ReplyDeleteIf your not confident in doing it yourself Trevor get it fixed by experts, not a local shop, cost £40 or so. Try to keep your favourite lens on at all times. A new sensor will cost you a lot of money.
