A new Tamrac Evolution 6 was with me 8 days in use. I am so moved and driven wheel. He was charged with the camera Sony A77 with an attached alternately Tamron 18-270 / 3.5-6.3 and Tamron 17-50 / 2.8. Furthermore, the backpack was a small metallic table tripod, a spare battery and various odds and ends. In the upper bag still fits a Metz flash 44 AF1, and my Tamron macro 50/2 will if necessary also space in the lower photo tray. However, of all additional lenses I have to remove the lens hood, otherwise it will be too tight. However, the aperture will also still a niche between the sides lying camera and the upper compartment. At the time appointed to the camera lens, the shutter can remain - very convenient. All this, however strongly depends on the skillful setting of the lower compartment; there must be a little thought and tried. With this equipment the backpack weighs about 4.5 kg. Outside can still be a tripod attached, such as a monopod or a light tripod. This must, however, decreased, if you want to access the middle accessory panel. Without tripod of external access is possible to all subjects. But you should memorize, behind which the three side pockets the required equipment is housed. One should get into the habit the same: After removal of the part the pocket flap must be closed immediately. Otherwise there is the risk of falling of the expensive parts. The backpack can be worn very comfortably, thanks really clever features. Even a hip belt is which can be completely tucked under the back cushion if needed. I have not used it, especially since he would have to be opened when accessing Always. The padding for the Photo and seems sufficient. The Sling-function could not convince me; the friction on clothes attracts a repeated procedure, the T-shirt. On a smooth, closed outdoor jacket like that go better. I have found another method. I slip with the right arm of the belt and was hanging his backpack on the left shoulder; then I take over the side pocket of the camera. This is also reversed when the lower tray has been previously set up accordingly. Particularly pleasing is the stable stability when placing it onto the floor by two large square plastic sheets. Also, all belts can be fixed against Umherbaumeln - because sometimes a manufacturer has demonstrated an understanding of the practice. For me, this is the ideal backpack and I'm satisfied with the purchase. The quality promises a long durability.
