About rain tightness and clipped on a belt, I can not comment - I protect my camera bag if I transported in a larger purse, or backpack. Removing the camera from the bag when the bag is in a rucksack and only the camera is needed to function properly, just as the fooled. The bag is plenty big, so that succeeds even without having a look and not a bit is pfriemelig.
Due to the good padding I'm not afraid that the camera something happens - even if other things heavier load in the backpack.
The memory card SDHC 8GB Samsung Essential Class 6 performed without problems and quickly their service.
For me, a very good buy!
