Sony A9 Auto Focus Speed Test for Video (Video Demo)
By Steve Huff
Hey all! Just thought I would do this one for fun today, and to show others out there who may be curious about the AF speed with the Sony A9 for video work. The A7 series before it had slow AF for video, and I normally used manual focus with the A7RII for that reason (for video) but the A9 is FAST! Not only will the A9 be my go. to photo camera but also my go to video camera for my reviews, vlogging and even some production work. I do not need Slog for my needs so the A9 is fantastic. With its low light abilities as good as I could ever need (for video) and AF speed 2X as fast as the A7RII for video, this camera surprises me more and more by the day. Check out the video below for a demo of the AF speed with video using the 28mm f/2 lens:
