Cleaning M8 and Sensor Loupe

Hello all,

 

I am comfortable enough wet cleaning my M8, but I always wonder if I can do this more efficiently/effectively. Recently a friend said he swears by the Sensor Loupe from visible dust. Given the very different flange to sensor distance on the M8, however, I wonder how well this would work. Can anyone comment on this? Additionally, Does the visual check save multiple cleaning/checking cycles?

 

Thanks,

 

Donald

I use the Visible Dust Sensor Loupe on my M8. It works well. It is not difficult to focus but as I recall it does not sit directly on the flange. (But then it does not sit directly on the flange on my 50D.) I have the 5x loupe. I think that there is a 7x loupe now.

I've used one since they came out. It revolutionised sensor cleaning for me - and I use it on full frame Canon DSLR and my M8s. The Arctic Butterfly's great when you're on the road and can't carry canned air - and the bigger brushes are perfect for regular maintenance cleaning. I've not needed to use a wet system in years.

 

Hope this helps.

I have and use one of the loupes but I still take a picture of a blank PC monitor screen, moving the camera in a small circle while taking the image, or of a clear blue sky, which hasn't happen to often lately here in Atlanta GA, just to check that I have all spots removed. Sometimes I still have a faint spot that you can not see with the loupe.

 

I figure if I'm taking the time to clean the sensor I want it totally clean.

 

As far as the mount to sensor distance I don't find it a probelm. I just move my eye in or out until the sensor is in focus through the loupe. I even move the loupe off the mount to get it to magnify a little larger and or to look into the corners a little better.

Thank you all for your quick responses. I will try the loupe. I tend to go through several cycles of brushing, wiping and photographing to test for residue. Ultimately, I get a clean sensor, but I think this will make the process more reliable if I can see what I am doing more directly.

I have used the loupe to good effect with the arctic butterfly. resistant dirt etc however requires loupe & wet cleaning... Chris mentionned compressed air... Thought one should never use that on a sensor! I don't...;)

 

re Compressed air - absolutely right - NEVER in the chamber. You use canned air to electrostatically charge the Visible Dust brush before you use it on the sensor - that way it picks up the dust rather than spreading it around. You then clean the brush with the air.

 

NEVER in the chamber!

I have the sensor loupe and it is a very useful tool for all sorts of things. I have not found it very useful for cleaning the sensor. Most of the sensor marks I get, do not seem to be visible with the loupe. I find the usual test method of using a long lens defocused on an evenly lit sky is better at picking up dirt or splodges.
