I had the Sling Bag from Rollei now two weeks in continuous use in the Alps and have to say that the bag has always made a good impression. I had no high during continuous use in all weather conditions significant problems. Whether the Sling Bag system for a work, everyone must try out for themselves. I have, for example are the tours Camera worn continuously despite Sling Bag around your neck, just around the camera faster To have ready for use. Good to stow away to other equipment, which nevertheless quickly must be accessible, it is still a good solution.
The bag has one large and one small pocket in which one problem-large Lenses and DSLR cameras can store. I use them for example for a Nikon D600 Tamron 24-70mm + 4 with Nikon fixed focal lengths and do not have any space problems. The Big Bag is as usual divisible with Velcro pads.
Unfortunately, I was also in my copy not promised rain cover, no tripod mount and find no great inner pocket. Therefore, there is a point deduction in the B note.
