Looking for the ultimate professional camera? Then the Nikon D4S ($6500) might just fit the bill. The ultra-powerful DSLR features a 16.2-megapixel full-frame image sensor thats been paired with Nikon’s Expeed 4 image processor. All this means is that this camera is much better at shooting in low light conditions than its predecessors, even if you need a faster shutter speed. It also has a buffer that’s big enough to hold 200 large JPEG frames before it’s filled up. And if you’re a video buff the Nikon D4S can shoot 1920 x 1080 footage at 60 fps. The Nikon D4S is now available for pre-order.
