Looking for a suitable safari photo backpack for a Nikon D700 with multifunction handle, normal telephoto, 70-200 2.8 telephoto and telephoto converter, and tripod and flash, I came across the Flipside Sport 15LAW. There were also a KATA and a Tamron to Wahl.Userberichte from USA encouraged me to take the Lowepro. In a 3-week desert safari in northern Namibia I have not regretted the decision for a second: the part is incredibly robust, incredibly convenient, incredibly receptive. Five great benefits for my applications: First fit the camera with an attached handgrip and a long pipe with converter completely into it (and large flash, two additional lenses and small items have also enough space). Second, the flip before the belly of changing lenses is something practically. Thirdly, I find class how water bottle and tripod are included. Fourth, the part in no time from dirt, dust and scratches is exempt. Fifth, the backpack carries even when fully loaded on long distances incredibly good.
My recommendation: fully positive, especially since the price of this service seems to me unbeatable.
