My entire camera kit fits in this Think Tank bag.

[OK, so my lighting gear doesn’t fit, but I work with available light almost exclusively anyway.]

Inside: 2 cameras (Fujifilm X-Pro1 and X-E1), 4 lenses (every compatible prime lens Fujifilm currently offer), a heap of batteries and a heap of SD cards.

Weight: not much.

Now you know why I went mirrorless. Why I chose Fujifilm is coming up soon.
