Sony has released a number of NEX cameras. They fall into three model lines at the moment:
- NEX-3, NEX-3C, NEX-3F—these are Sony's low-end model, in order of introduction. There was a significant step forward (sensor wise) with the 3C, and a modest redo of features on the 3F, making the 3C and 3F the preferred versions of this model.
- NEX-5, NEX-5N—the mid-range model was always a strong performer, with the 5N update being a modest change. The big change with the 5N is the availability of a very good optional EVF (equivalent to the NEX-7's built-in EVF).
- NEX-7—the high-end model was launched right at the time of the Thailand floods in 2011, which delayed wide availability of the camera. At it's launch it was the mirrorless camera with the most pixels (24mp). That, coupled with the built-in EVF, redesigned controls, and small, prosumer type package made it one of the desirable high-end mirrorless cameras from day one.
