I bought this bag for my Nikon Coolpix P510, which is quite a bulky camera. It would easily take a DSLR if the lens wasn't more than an inch longer than mine. I have 2 spare batteries in the side pocket, but it would take 4. The extended battery, USB charger and cable go in the front pocket, so I can charge a battery while using the camera. Memory cards can go in the mesh pocket under the top flap. The bag is well padded and everything is well protected. Its a very well thought out and strongly made bag. I give it full marks for a bridge camera, but only big enough for the smallest DSLRs.
