These days it seems even the Amish are carrying digital cameras, and those of us that shoot in urban environments know it's not long before the lens gets dirty. Specks on the glass can foul your autofocus and light sensors, turning your $300 toy into a Lomo.

To keep the glass clean, we're supposed to use that space-age cloth thingy, which most of us fail to carry around. To solve this problem, Sigma has produced the Micro-Fiber Lens Cloth Keychain, which goes for less than four bucks. And don't worry; the cloth stays clean inside its own little pouch, so your pocket lint doesn't ruin your shot of those rule-bending Amish.
