A long time I had to search to find a perfect carrying case for my Olympus E-M5, including lenses. Most bags and backpacks are designed in terms of size, unfortunately for SLR cameras whose lenses are known to be substantially greater than that of system cameras. The Lowepro SlingShot 102 AW has compartments that are not very deep and therefore are perfect for my compact equipment. As DSLM users one has the advantage of using much smaller lenses. My biggest objective, the Lumix 45-200mm, filled here by the top and bottom of the compartments from perfect. The compartment where the E-M5 is indeed still a bit too big coming in, but much better is not easy. As long as the camera in the compartment has a reasonably secure grip and not wild flings during transport through the area, that's fine with me. 2 additional lenses and the rest of the equipment fit in loosely. On the side of the backpack I can also fix my tripod.
Of course it would have been even nicer if the backpack would have two straps to distribute the weight on both shoulders. But one just has the advantage that you do not have to settle the backpack to get at your equipment. Still not mind facing the strap particularly because my equipment anyway compared to the DSLR counterparts fail very easily and I must therefore carry little weight on one shoulder. So I can particularly recommend system camera users warmly this backpack. But is also just adequate for DSLR users with small lenses.
