I had two X-H1 loaded with the beta v1.10 mounted with the XF50-140mm and XF100-400mm lenses. I can feel the snappy AF performing well in the late afternoon light right the way. The bull riding started around 8:30pm and the AF was still performing well in low light. In comparing with the X-T2 with the latest v4.10, I would say the X-H1 AF performance is slightly ahead of the game. Don’t get me wrong, I will still have my X-T2 in my bag but I have paired the the XF50-140mm and XF100-400mm lenses with the X-H1 as default.
The following video is created with 37 frames shot by X-H1 with XF100-400mm lens at 11 frame per second, AF-C with AF-C custom setting 4.
