A delight ergonomically, gives truly glorious images (I think the massive pixels really help), beautifully built. Less good? AF is very good indeed but not quite up to D5 level. It is amazing in low light but above say 6400 needs to be properly exposed to be really clean . 12800 is probably the upper useable limit. Files print very well indeed up to A3+ but would need work to go much beyond that, and 12MP doesn't leave huge room for cropping depending on what you are going to do with the image. But it's brilliant value.........
