EXTRA !!! I bought this bag for a Photo Safari ... He has incredible composure while being not too bulky and not too heavy. (I compared with the Slingshot 202 AW that was far too small for me and Fastpack 250 a little too thick, but my friend has took his computer to store) I return without problems: a box with lens 70-200 F4 + doubler mounted with the visor backwards + 2 other smaller goals + all cables, chargers, compact and all cleaning equipment. And personal compartment on the top is very spacious also: book, sweater, hat, binoculars, snacks. There is also a front for storage of books, pen, manual ... And a room for one or two small bottles of water. Obviously, once it is loaded + heavy ... :-) You can safely remove the device sideways, without placing the bag on the ground, even if it is a little less simple than with the slingshot 202, but it is a blow to take is done quickly. Precisely it is highly reactive with. Highly recommended! And an amazing price, compared to what I could find in the shops that everyone knows .... I'd be more elsewhere, especially since I was delivered in two days, that I was able to order several bags to compare and return the one I did not want, being repaid very quickly. THANKS AMAZON, they all realized in my opinion!
