The bag seems resistant (to be confirmed for use). The interior layout is a bit disappointing. My Panasonic GH3 blithely walks there, the fault fixed by a movable partition ultra soft velcro. If I put my 20mm yet very little in the bottom of the bag, telephoto and housing abut it, if I did not put the bag is too big. It is very convenient ride for storage box between two shots and prevent it dangling from his belt. Similarly in case of rain, the unit is safe without the hassle of a huge camera bag. This case is obviously improved, but remains a very good product, especially for the price. Delivery is blameless.
