l bought a visible dust arctic butterfly from CP and was a little over enthusiastic to try picking out my 3 specks that were visible in my sky shots from my recent trip of the grand canyon. Opened the package over dinner, set the cam to M-up, whizzed the butterfly a few times and started heading for the sensor only realising after 2 strokes that it doesn't look like the sensor. Then i recalled that the M-up on the dial is not for cleaning and does not expose the sensor. Didn't think it was a big deal, went to the menu and activated the 'lock mirror up for cleaning'. After a few brushes, i took a test shot and to my horror, the whole sensor was a mess and i'm flying to sydney in 5 hrs for a wedding shoot!
It was 7pm, so i left my food uneaten and rushed back to CP hoping its still open. Luckily they were just about to close but attended to my emergency. Examined under a lighted loupe and saw the most heart wrenching, depressing sight ever. Amongst the smears, i thought i saw a scratch on the surface too.
I was advised to get a sensor swab with the eclipse solution to clean the sensor.
