  • When we reviewed Sony's A7R mirrorless camera, we were thrilled by its combination of a full-frame image sensor and a compact body. The Sony A7 offers both, and yet it's even more affordable.

    The Alpha 7 is a great camera for the photo enthusiast looking for a high-quality, lightweight camera that will reward with excellent images, but be prepared to invest in Zeiss prime lenses to do the sensor justice.

    The Sony Alpha 7 is one of, if not, the cheapest full-frame digital cameras currently available, undercutting both the Canon EOS 6D and Nikon D610, whilst also being considerably smaller and lighter.

    In terms of operational speed and all-round performance, the A7 delivers on most counts. Shutter lag is only notable by its apparent absence, and image processing times are slightly faster than the A7R thanks to the smaller Raw files that the A7 produces.

    Sony Alpha ILCE-7 (A7) is a great alternative to similarly priced entry-level full-frame dSLRs, as long as you don’t need speedy continuous shooting.
