Is the panasonic lumix s 14 28mm f 4 5 6 macro good for vlogging?
It's a reasonable pick for vlogging on a full-frame body, with some caveats. The 14-28mm range covers the wide end of what I suggest in my vlogging checklist, since 14-20mm full-frame equivalent is what keeps you in frame at arm's length. On APS-C it becomes 21-42mm, which is too tight for most vlogging.
Two things to weigh. The lens itself isn't stabilised, so you'll be relying on the body for that. And f/4-5.6 is fairly slow, so it's happiest in good light. If you're shopping for a body to pair with it, the Panasonic Lumix S9 is on its fit list. Check that any body has a front-flipping screen and a microphone input, and plan for sound from the start, as the audio notes explain.
