Visible Dust, maker of image sensor cleaning products for digital SLR cameras, has recently added two larger-sized brushes to its Sensor Brush line.
The new brushes are aimed at medium format digital back owners. The 36mm brush is for 16MP cameras with a 36mm x 36mm capture area, while the 40mm brush is for 22MP cameras with a 40mm x 50mm capture area.
Both brushes feature a fan-style bristle arrangement and narrow-width handle.
The new brushes are the latest in a series of changes at Visible Dust, a small, Edmonton, Canada-based company whose products we first wrote about in October 2004. That article was a veritable lovefest for Sensor Brush and Sensor Clean: then, as now, we found Visible Dust's products to be an effective and practical way for the working photographer to keep an image sensor's cover glass free of dust.
Since our initial article, Visible Dust has redesigned the 16mm, 20mm and 24mm Sensor Brush sizes to be fan-style, revamped the purchasing process by improving the online order page and adding telephone order/customer service lines, grown their staff to better handle the volume of orders, moved the Visible Dust web site to a more stable online home and published how-to videos demonstrating sensor cleaning.
Thanks in part to a massive swing in the exchange rate between the Canadian and U.S. dollar in 2004, however, U.S. residents can also expect to pay more now for Visible Dust's products, while changes to the multi-brush bundles offered by the company may mean that you have to spend more to get the optimum combination of Sensor Brush sizes to suit the cameras you use.
All in all, however, we remain impressed with the quality and usability of the Sensor Brush and the fact we can wet-clean a digital SLR using Sensor Clean with virtually no risk of streaks, which is a first for us here in the dry, dry air of Calgary, Canada. So it's great to see that the fledgeling company is continuing to improve both their products and how it sells and supports them too.
