We just returned from a Paris to London vacation and during the London segment I noticed a lot of photos with blobs in photos with clear blue sky.
The last week of May in London seemed to be pollen week. I was sitting in a park near the Thames and you’d think it was snowing. Without thinking I swapped the lenses on my Sony NEX-5N and like a magnet the electrostatically charged sensor sucked in pollen and dust like a Dyson.
On the left is a typical 1:1 crop example of a sensor dust blob. Little choice but to clean the sensor and at $40 a cleaning I decided it was time to buy whatever I needed and learn to do it myself.
I bought the swabs, cleaning solution plus a SensorKlear™ loupe, pen and blower. Then I watched a handful of YouTube videos on sensor cleaning and decided to have at it. Blowing was tried first and did almost nothing to get the pollen off, so I braved a wet cleaning.
First came the wet swabs, looked much cleaner but the loupe revealed some stubborn smudges. A final brushing with the SensorKlear pen seemed to do the trick.
My only gripes are 1.5x cleaning swabs are hard to find although 1.6x seem to work just fine. Also the SensorKlear loupe won’t focus properly for mirror less cameras and you’ve got to hold it away from the camera body.
I’m delighted with the results and since it’s a beautiful day here in Toronto I’m off to snap some blob free photos after a Sunday brunch.
