People's full-frame flagship: diagnostics of Sony Alpha 7 III

The Sony Alpha 7 III (ILCE-7M3, 2018) has become one of the most influential cameras in history. New 24.2 megapixel BSI CMOS sensor with phenomenal dynamic range, 693 phase AF points, 10 fps continuous shooting, dual slot, 5-axis IBIS and built-in flash storage - all at a price that has blown up the market. The Alpha 7 III immediately became the professional standard for wedding photographers, videographers and freelancers around the world. Commercial exploitation is usually very intensive.

A wedding photographer with an Alpha 7 III takes 2,000-3,000 shots per day. Over the course of several wedding seasons, the counter will easily exceed 200–300 thousand. The professional case with moisture protection maintains its appearance perfectly. The system meter is the only objective assessment of the load on the mechanics.

Revolutionary sensor and 200,000 shutter lifespan

The Alpha 7 III shutter is rated for 200,000 guaranteed actuations. In practice, A7 III shutters often last 300+ thousand. A camera with mileage up to 100 thousand is a great buy. Over 180 thousand - a professional assessment is needed. The electronic shutter (silent mode) does not wear out the mechanics.
