Visible Dust has announced two new products. First is a version of the Arctic Butterfly that has a built in LED to illuminate the sensor area while you're cleaning. Anyone who's seen me clean a camera knows that I wear a headlamp to effectively do the same thing. You shouldn't try to clean a camera without being able to see. The difference in approaches is this: I direct the light where I need it with my head, the Arctic Butterfly 724 (Brite) directs it mostly to one side of the brush.
The other new Visible Dust product is the Vswab, swab for FX sensors that is only wide at the tip. This, too, makes it easier to see what you're doing, and keeps the swab from too easily rubbing against the frame around the filter. (Disclosure: Visible Dust has mailed me samples of their new products to try.)
