Thon Case Zoom B6

The case is sturdy and fairly heavy for its size (about 3.5KG. With the zoom inside it'll be about 5.5KG). The B6 fits perfectly in the pre-shaped foam and it feels secure within the box while travelling. The spare room in the back of the casing can be used to bring a power supply or a power bank. The locks are heavy and lock (and unlock) in opposite direction to each other.

And that's really my only very minor gripe with it. I would have preferred them to lock the same way. On the other hand, you can't just try to lock (or unlock) it without paying attention and risk not locking them properly which is probably why it's buit like this. It's something you'll get used to.
