a reminder on wet sensor cleaning


menos I M6

This post actually fits into any removable lens camera forum here.

I put it into the M8 forum, as I cleaned my M8.2 and many new M8 users (finally got their second hand sample) might find, the previous owner was a pi… - I mean, didn't perform a sensor cleaning before selling ;-)

 

Finally, I went over my lazyness and cleaned my M8.2 sensor after a while.

I had enough of dust spotting the stopped down photos in Lightroom.

 

One specific big dust bunny can be found in all my Le Mans and Europe travel shots -annoying!

 

After 2 runs I had the sensor clean except for something, that looked like a smear and two distinct little spots.

 

I went for a few more runs and these things drove me crazy!

 

Went for a coffee and while sipping the cup, a defect on the wall paint got my attention - which turned out, to be exactly that strange little smear, followed by two distinct dots, I saw on my test shots.

 

You know the rest…

 

Remember during wet sensor cleaning:

 

- inspect your tools (no dusty old swabs, …)

- inspect your test target (wall, sky, …)

- change lenses during test shots (and keep them clean - rear element especially)

- when moving furniture within your apartment - repair the damage, you have done! (took a pen remover and 1 minute work in this case - much less nerves and Eclipse E2, I wasted, to clean the wall scratch off my sensor ;))

 

For starters with wet cleaning, I advice the most easy and risk free procedure:

- do only one swab move at a time

- close the shutter directly after removing the swab out of the camera, to prevent flying dust from settling on the freshly cleaned sensor

- mount a lens and do a test shot

- inspect the test shot

- test shot ok? - stop cleaning!

- test shot too much dust for your taste? repeat!

 

Don't get worked up because of one or two dust spots left!

I decide, based on position on the sensor, quantity and severeness, to clean again or leave it be.

Spots on the very, very outer edges (left or right) are the most hard to clean, depending on your swab technique.
