I use an EOS Rebel T6i and Cannon lens EF-S 24mm f/2.8STM for daily vlogs. It does fine in good lighting, but anytime shadows enter the shot or it is dark the camera really struggles to grab and hold focus. I've tried auto focus on face tracking as well as just whole scene with little noticeable improvement. Is it the camera or the lens the bottle neck? My nikon d3300 with a Sigma 30mm f/1.4 focuses much faster (even though I was under the impression cannon had better/more focus points). I know the 1.4 lets in more light, but it really feels like the T6i is leaps and bounds behind the d3300.
Thanks for your thoughts!
