If you shoot with a DSLR camera, I highly recommend a Ruggard Triumph 45 bag. I use mine daily. It has room for my DSLR Camera with the lens on it, and two additional lenses.
This padded backpack protects my gear while having an indispensable side pouch that I can unzip and pull out my camera at any time. It keeps me ready to shoot at all times.
