The premium end of the compact camera market appears to be one sector that remains reasonably robust in what is generally a declining market. Offering full manual control for advanced photographers, they're often the first choice of both those looking to take a step up in image quality and control, and those wanting a less bulky camera to carry around when the DSLR is inconvenient.Nikon's P7XX range has always been Nikon's attempt to fulfill that need for Nikon photographers, taking on the incredibly popular and well established Canon G range. Canon recently refreshed its model, in the shape of the G16, so it's no surprise to see Nikon follow suit with the Nikon P7800, replacing last year's Nikon P7700. Featuring a 12 million-pixel resolution sensor, Nikon has chosen to keep the same physical size of 1/1.7 inch.
