Is the sony e 55 210mm f 4 5 6 3 oss good for video?
Partly. The Sony E 55-210mm f/4.5-6.3 OSS has two things video shooters want: it's stabilised and it autofocuses. Its reach is the problem for most video work, though. On APS-C it frames like 82-315mm on full frame, so it's a telephoto lens, not a wide one. For vlogging, you want something around 16-20mm full-frame equivalent, as the video guide explains.
It makes more sense for telephoto subjects, like interviews from across a room, wildlife, or sport. Its maximum aperture also drops as you zoom in, so keep an eye on exposure when you change focal length mid-shot. On a body like the Sony ZV-E10 II or the Sony FX30, it's a usable zoom for those jobs. Whatever lens you pick, budget for sound separately. See audio.
