Is the canon ef s 35mm f 2 8 macro is stm good for video?
This lens can work for video, but it isn't my first pick for it. It's stabilised and has autofocus, which helps when you're moving. On APS-C it frames like 56mm on full frame, a fairly tight view. That suits a seated interview or a talking head across a table, but it isn't the wide look I recommend for vlogging, where you hold the camera at arm's length.
It fits a long list of Canon APS-C bodies, including the Canon EOS 80D and the Canon EOS 90D. Whichever body you pick, budget for sound too. A good microphone matters more than the lens, so see the audio advice before you buy.
