Sony's breakthrough full-frame mirrorless, bringing 5-axis IBIS to the A7 line.
The Sony A7 II was launched in late 2014 as the world's first full-frame mirrorless camera with 5-axis in-body image stabilisation. With a 24.3MP sensor, improved autofocus over the original A7, and IBIS, it became the camera that convinced many photographers to take Sony mirrorless seriously. It democratised full-frame stabilisation.
The 5-axis IBIS provides approximately 4.5 stops of stabilisation with any mounted lens, including adapted vintage glass. The 117-point phase-detect AF system is a significant improvement over the A7 but still hunts compared to later models. Burst rate is 5fps. The body is compact magnesium alloy with improved ergonomics and a redesigned grip over the A7.
The A7 II is praised for bringing IBIS to full-frame at an affordable price and for excellent image quality. It is criticised for battery life which is poor at around 350 shots, the EVF which feels dated compared to later models, and 1080p-only video. Menu ergonomics are notoriously unintuitive.
Very affordable used and one of the cheapest ways into full-frame mirrorless. Check the shutter mechanism for any unusual sounds, verify IBIS operation by half-pressing the shutter, and test the battery as these cameras drain batteries quickly. Budget for extra batteries. The A7 III is a massive upgrade if budget allows.
