Is the tamron 17 28mm f 2 8 di iii rxd good for vlogging?

Yes, on a full-frame body it's a sensible vlogging lens. Our vlogging guide suggests a wide view of roughly 16-20mm full-frame equivalent at arm's length, and this lens starts at 17mm. Its f/2.8 aperture also helps when you're filming indoors.

Two things to watch. The lens isn't stabilised, so the camera body needs to do that work. And on APS-C it frames like 26-42mm, which is too tight for arm's-length shooting. Pair it with a full-frame body such as the Sony ZV-E1. If you'd rather use an APS-C body, the Sony ZV-E10 II is a better fit for a wider lens.

Don't skip sound. Budget for a microphone from the start, because bad audio hurts a video more than soft focus does.
