Sony Alpha a7 III 2018
The 24.2MP full-frame sensor and 693-point AF system with Real-time Eye AF deliver sharp, reliable subject tracking across nearly the entire frame. Its oversampled 4K video with S-Log3 support and 5-axis IBIS make it a capable hybrid tool, though the 1987g weight and lack of weather sealing limit its travel appeal. This camera is best for portrait and event photographers who need dependable autofocus and strong low-light performance in a full-frame body.
