Sony Alpha a7S II Black 2015
Its 12.2MP full-frame sensor prioritizes large pixels for exceptional low-light performance, capturing clean 4K30 video with full pixel readout and an ISO range expandable to 409600. The compact, weather-sealed body integrates 5-axis in-body stabilization and S-Log3 gamma for enhanced dynamic range in a portable form factor. This camera is best for run-and-gun videographers and vloggers who need reliable handheld 4K recording in challenging, dimly lit environments.
