The Sony Alpha NEX-5N is the fourth model in Sony’s NEX line of APS-C format mirrorless interchangeable lens cameras. Just as theNEX-C3replaces the NEX-3, the 5N is a direct replacement for its predecessor the NEX-5, using the company’s latest 16.1MP CMOS sensor in place of the previous 14MP chip. Although the 5N is nearly indistinguishable from the NEX-5 on the outside ( and is bound to be regarded as such by many casual observers) , it is actuallya very different camera, and one that is worthy of serious attention.
