My current camera bag is no longer fit for purpose. Not only have two zippers come away, taking fabric with them but the innards are really far too soft and it doesn't really carry enough - one body, possibly 1 extra lens and one flash. I need something bigger, more robust, but light. Any makes models that anyone's aware of these days? It has been so long since I bought a new bag I feel as though I don't know where to start!
