Another Cleaning Example

A friend came over today with his Canon 30d. This camera was only a couple of months old, had less than 100 shutter activations, and the lens had been on the body since its purchase.

So, how did the sensor look? We shot an image of the sky at f/22 and brought up the contrast in PS to highlight the gunk.

Ouch Canon! Where are you assembling you cameras? Certainly, not in a clean room. The spots number in the hundreds (Click on any image to bring up a larger version).

Now, one round of cleaning with the Sensorklear and rocket blower. Not bad - the number of spots is less than a dozen or so. Perfect? Not by any stretch, but certainly manageable. Subsequent cleanings will probably reduce the problem even more...

I'm a guy living in the Netherlands, Europe.
I think I'm going to try (use) this method too.
I'm not a fan of the common and too expencive methods.
It's only a pitty there are not more possitive (and negative) comments on your site about the SensorKlear Lenspen.
Sorry if there are some writing mistakes...

Thank you for visiting the site. Although I have solicited comments from other users regarding the Sensorklear, unfortunately their experiences have not been forthcoming.

For my purposes which involves a fair amount of travel and frequent "field cleanings" the Sensorklear has been the easiest and most effective method of cleaning my cameras.

When you have the opportunity please feel free to leave a chronicle of your experiences.

Hi sensorman,
Thank you for the review on Sensorklear. I will be getting one after reading your reviews and it seems to be effect and yet safe for the CMOS.

Have you tried to clean the main reflex mirror and focus screen with this pen?

No, I don't believe that the Sensorklear was designed for cleaning the mirror or focus screen - the amount of pressure needed would probably dislodge or even break the mirror. One could probably use the brush end on the mirror, though I couldn't recommend that either. Generally, I take a hands off approach to either and blow dust off in those circumstances.
