Incredible backpack, i already have one. this is superfluous to my requirements. Here is a link to the aussie supplier, save a few bucks and buy mine :)

May swap for a Canon branded Fisheye.

Very rugged construction, perfect for nature.

Green shots are from the website, black bag is what you will receive, the same model but in black.
