Is the tamron 16 50mm f 2 8 a good for video?
Yes, with a few caveats. The constant f/2.8 keeps exposure steady as you zoom and gives you a soft background when you want one. At 305 grams it's light enough to hold for a while, which matters for handheld work, as our video guide notes.
The catch is the wide end. On APS-C bodies, 16mm frames like 24mm on full frame, which is tighter than the 16-20mm our vlogging advice suggests. The lens also isn't stabilised, so for walking shots you'll want a stabilised body or a gimbal.
From its list, good bodies to pair it with include the Sony ZV-E10 II, the Sony a6700, and the Canon EOS R10. Whatever you choose, plan for sound from the start; see video audio.
