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...

Review - 9 month update

Since the last posting my sensor cleaning experience continues to grow (more than 60 uses so far). The Sensorklear has been used numerous times on the following Canon camera models: 1DMkII, 30D, 10D, and Rebel XT.

I've traveled throughout the US, Europe, and the Middle East without encountering any airport issues. The Sensorklear continues to function quite well without any evidence of degrading or causing any damage to the sensors or shutter frame assemblies. It proved particularly adept at removing a few "oil" splatters on the 30D sensor.

With repeated use I've noticed that the interval between the need for subsequent cleanings generally increases. This is in keeping with Lenspens' own lab tests which demonstrate that the lenspen creates a dissipation in static charge.
