To be very clear we hate dust on sensors and even more to clean the sensors. Here is our brief history about dust on sensors. The old favorite (if we ever had one :-) ) method was cleaning the sensor with sensor swabs and some special fluids.

Then a few years ago VisibleDust presented their first Sensor Brush. We had one of the first reviews by Rick Decker on our site. While the sensor brush seemed to work fine there were some inconveniences to overcome:

• you need canned air (not so good on flights)

The canned air was needed to charge the bristles. Later VisibleDust invented the Arctic Butterfly where the fast rotation of the brush were helping to charge the bristles. Also these brushes seemed to work fine but some users felt a bit uncomfortable with the placement of the on/off switch (could be accidentally be hit during cleaning on the sensor).

The new Arctic Butterfly 724 is a way more refined design:

• Even the case is nice for travel (remove the batteries)
• Switch can hardly be hit during operation
• Works as good as ever

Operations:

• Set camera to sensor cleaning mode
• Spin Arctic Butterfly 724
• Brush very gently sensor from one side to the other
• Do not touch the chamber while inserting the brush into the camera
• Repeat this 2 x-3x

We needed to clean our second hand Canon 20D and it just worked fine. We don't expect that really all dust spots are gone but we reduced the dust spots to a very manageable level. All worked fast and painless (and we were confident not to harm the sensor).

We are not alone to

this product.

While we still don't love to clean our sensors we have now found a product that even works for us.
