Perfect for a Nikon D5100 equipped with a lens Nikon 18-200 VRII. There is room for the sun visor and removed the bulb to remove dust. The front pocket can even contain a wallet and batteries or memory card. For the water bottle and windproof better to have an independent backpack: if a pickpocket slipped to hand, there find anything important while you take care to keep one hand on your bag tamrac ventral ... A choice that matched my criteria.
