How do you get rid of dust on sensor? Can you use a lenspen? I have tried blowing it out, but that doesn't really help. aRRGHHHH!!!
Rather take it in to an authorised dealer.
I'm too 'scared' to do such things myself.
i just use a air blower, working quite well for me so far
I have been reading, don't use canned air as there are some chemicals in the air that is used as a propellant and can stick to the sensor. Compressed Co2 is apparently the best option as long as there is no OIL. Rocket blower is still the best. But I have not managed to get everything off my sensor. Some of the dust is rather sticky. I have not tried using a sensor swab or anything else yet. arrrghhh dust.....
vacuum cleaner?

LOL
I just use a bicycle pump with a ball adaptor on it to make it a higher pressure. Works well so far, but i have more dust now grrr
