This video has been hitting the blogs recently, but I didn't really watch it until it wound up in our inbox a half a dozen times. I guess I should say that this is probably the absolute textbook way to clean a lens but does anyone actually own all these rocket blowers, cleaning brushes, and cleaning supplies? I guess since I've never scratched a lens, I've always found one of these to be acceptable. Instead of using compressed air, I've always just used my mouth...am I a really bad person?
