The a7 (and the other two a7 models) is an amazing camera and the future of photography, and its predecessors will almost certainly kill DSLRs. It offers full-frame 24-megapixel image quality, similar to a Nikon D610, but in a smaller, lighter package. The electronic viewfinder provides far more information than an optical viewfinder, and the ability to adapt almost any SLR lens provides incredible versatility for photographers capable of manual photography. This is my current favorite full-frame mirrorless camera. If you want full-frame results, an electronic viewfinder, and the smallest camera possible, the a7 is the perfect choice. If you don’t mind an optical viewfinder and a bigger body, the Nikon D610 has similar image quality, better focusing, and access to a much wider selection of native lenses.
