The connection to the Chest Harness works just fine, all mounting points are in the right place. The bag itself already offers plenty of space, which can be extended by two Sliplocktaschen. The docking points are on the sides.
Now for the hook and star deduction:
Thought is the case for long telephoto lenses. They can also be very good. And there is still enough space in the interior over for additional accessories or a smaller lens. But for the interior layout is too inflexible. The bridge is expected to be quiet yet 3cm longer and in the region without Velcro. Similar to the Apex series you would have in a vertical partition an automatic cushioned lid on the camera's grip may rest instead on the lens in the separate compartment. With horizontally retracted partition like coming to the parts including, without always loosen the Velcro. However, the main point of criticism is the insufficient surface for Velcro. A few more square centimeters would make the interior layout much more flexible. Or why completely using only the fleece strip instead of two materials are not the same for the inside?
Otherwise, the bag fulfills precisely its purpose: to hold a camera with telephoto sure the body. With the Chest Harness, the shoulder strap and / or the ability to pull a belt. Reinpasst loose an alpha 230 with Minolta 70-210 F4 and attached lens hood. A Dynax7 with battery grip fits necessary even purely, however, slowed down the access significantly since the case in scope rather tight in case he sits.
