Sigma 18-35/50-100 + Speedbooster + Panasonic GH5/G9 Autofocus Test!

The great autofocus test of the 2020s! In this video, we go through a combination of Sigma 18-35mm and 50-100mm f/1.8 on a Metabones Speedbooster Ultra mounted on 1. Panasonic GH5 and 2. Panasonic G9, and test their autofocus speed and accuracy! What, that was a mouthful! We test everything from AFC, to AFS and video autofocus as well. How do they perform?! Let's see.
