I summarize briefly me, because it's already a lot has been written. The Bumblebee I bought next to a stretcher Lowepro Pro 600 AW. The Kata is a Camera and Photo Equipment Transporter used (Studio, museums, etc). The division with the separate lens bags I find it very successful. So you can take out a whole bunch lenses at once and has space for eg a large telephoto. The yellow inner color makes me happy, because one quickly finds his stuff even in a darkened studio. When transporting two cases it is better only a pack with battery grip. The square top (see photos) is somewhat flat. While you can squeeze in ne Kam with Battgriff, but then the lid already dents something out. Below the place is perfect for it. When carrying frame I'm not quite as euphoric. Compared to the 600 AW Lowepro executor (similar loading is just smaller), the harness does not cut as well and comfortably off. For not too long trips and not for heavy equipment but still absolutely top. What I personally do not like is the holder for the tripod. She is in my opinion too far out downwards. So the parking is impossible in the field and the backpack is with the support page in the dirt. I would prefer that people would stand sticking out over the backpack. I still give it 5 stars because that's whining at a high level. Quality is Katatypisch great.
