The Sony a6400 is highly regarded among YouTubers. The reasons are several. It has the same great autofocus technologies as Sony’s a7 III SLR, including 425 contrast-detection autofocus points, realtime eye autofocus, plus realtime tracking.
The 24.2-megapixel APS sensor of the Sony a6400 captures “oversampled” 6K data and then downsamples it to 3,840 x 2,160 producing superb quality 4K video. A flip-up LCD screen cements its current position as the best video camera for vloggers. Highly recommended.
