After the experience with the Mantona SLR Backpack Trekking (too small for Sigma 50-500) the next attempt. Even after 2 days the goods arrive - giant box of giant content. The complete opposite to the 1st attempt - here fits in half a photo shop. Pro: - Processing looks solid - Place without end - Very stable - To wear well - See zippers for me OK Cons: - The often criticized smell (I can usually smell hardly what - but the skin around myself) - The really positive height of the interior is negatively that one (of course nonsense but) can evacuate 2 cameras on each other in a compartment in theory, but since nothing inside to fix is provided, everything is flying around loose. - The huge storage space would theoretically also provide space for a daypack - but unfortunately not provided. - For me the bag is therefore unfortunately also unusable and goes back. Sorry Amazon!
