Size: 124 x 71.1 x 59.7mm Sony’s A7 line of mirrorless E-mount cameras has long been a popular choice for those seeking the benefits of a full-frame sensor, but one of the main trade-offs for that has always been portability: full-frame sensors are bigger, so full-frame cameras have to be bigger than cameras with smaller APS-C sensors. Step in the Sony A7C. The Sony A7C, the range’s latest addition, changes all that. It’s the smallest and lightest interchangeable lens full-frame camera around. It’s more akin to an APS-C model for portability – and, at first glance, Sony doesn’t appear to have sacrificed a great deal to get there.
