Cleaning the M8 sensor

Sorry for the umpteenth thread on this subject, but I want to make sure. From what I gather on this forum, this is recommended to clean the M8's sensor is: Visibledust swabs green brand (1:3x) and Eclipse E2 cleaning agent. I took note because theses items are available at my photo store. Would somebody be kind enough to confirm this is indeed good and efficient and, above all, safe? Thanks a lot.

I have hesitated a long time before I decide to do it. But I had more than twenty points of dust and it became necessary to clean the sensor.

I used Eclipse 2 and sensor swabs (twice), and everything gets fine, except one new point (bigger!) which I prefer to let. I remove it with LR or CS.

So, imho, these products are usefull.

Here are the "before" and "after" pictures.

FWIW, I had no luck at all with Dust Aid: all it did for me was to move things around. This may be because my spots weren't actually dust but were, eg, grease or lubricant or something from the shutter. Whatever the reason, I worked my way through a whole tin of Dust Aid in a morning and made effectively no improvement. By contrast, the combination you suggest – sensor swabs and Eclipse E2 – removed 90% of my specks on the first try (one firm sweep one way, then reverse the swab and repeat the other way) and the remaining 10% on a second try.

 

It's worth blowing the chamber clear with a Rocket blower or similar before you use the swabs, just to get rid of any loose stuff. If you're careful and if you don't mind smiling in the face of danger and tweaking the nose of fate, compressed canister air does a better job faster – but if you blow the propellant into your sensor, you could be in big trouble... you have been warned! :D

Try cleaning the back element of your lense. Don't ask me why I know :rolleyes:

I'll do that and'll tell you, because I've just checked pictures with other lenses, and you're probably right.

 

Shame on me and Thanks to you !

Right or wrong, the way I check for effectiveness of dust cleaning is to use a wide lens fully stopped down (f/22) & take a picture of a sheet of white paper, backlit with long exposure (1 sec plus) and move the paper around so there are no details from the paper. I figure if the dust doesn't cast a shadow on the sensor under this condition, it is clean enough. f/22, however is sufficient with a wide lens to show up dust on the lens elements.

 

If you want the ultimate dust detector, use a pinhole lens with the above test. Just about any fleck of dust looks like a mountain on the sensor. I'm still trying to figure out how to clean the pinhole lense ;)
