Cleaning a FF sensor DIY Wet method - RESULT!

Isn't that hard after all.

I noticed there were 2 bit of dust when I shot some quick HD films whilst in Rome, they were shot at F/7.6 or something, I seldom shoot at that aperture so I never knew. I knew there's bound to be some dust as I've had one 5D over a year, one for 6 months, changed lens countless times in weddings so it is not unexpected. As its a new year I thought i give it a clean. What was scary is the FF sensor is BIG, it is a lot bigger than the 30D to clean but it's the same principle so I had a go.

I cleaned both, both shot at F/22

1st 5D result

This one is pretty much perfect I think, I can't see any dust.

2nd 5D result.

By the time I done this the clouds had come out, but i waved it to create movement...I can see a tiny dot on the top right, but its F/22 and it doesn't show at the normal aperture, this 5D actually took me about 2 tries (I first cleaned it 2 nights ago) before I got it like this...annoying, at one point I made it dirtier! lol

That's money saved!

Oh, I got my 35L calibrated.

Focused on the Moss, F/1.4

This is how i did it.

Cling Film over the table. It does 2 jobs

1 - It attract the dust near the surface to it, so it removes some dust from the air
2 - Its cleaner than your table, no matter how hard you try to wipe it.

The guide I followed is this one.

Good tip with the cling film

I did mine some time back with a cotton bud and some ispropyl cleaner. It was a bit of a ghetto emergency clean at the time, but it actually ended up perfect.

Out of interest, how come you only noticed the dust with a smaller aperture?

you are putting everything in focus.

ideally you shoot into a sky, and wave it around. Dust will stay stationary as it is on the sensor.

Waved both of mine about outside and will check the images later. Hope they're clean though as I'll be damned if I'm going to poke around either with a swab.

If you don't notice it when you use it then i would go looking for it. Lol

Selling one so want to be honest, and if the other has then there will be trouble (it's almost brand new!)
