This material is exactly what I was looking for. I bought two Panasonic lenses (described below) and they came with cases that were pretty thin and didn't offer any shock protection. These bags from Neewer offer good protection against porosity. I used the small size on my Panasonic 20mm F1.7 and the large size on my Panasonic 45-200mm. They're both a bit off, but I still find them fitting. Now light taps on my lenses don't bother me anymore. Featured!
