Is the om system m zuiko 90mm f 3 5 macro is pro good for video?
It's a decent video lens, but only for a narrow kind of shot. The 90mm frames like about 180mm on Micro Four Thirds, so it suits tight, distant subjects, like a product, a close-up, or a subject you can't approach. It's stabilised and has autofocus, which helps when you're handheld or following movement.
It's a poor fit for vlogging. As the Video guide explains, a vlogging setup needs a wide lens held at arm's length. For that, pair a Micro Four Thirds body with a wider lens, and check the sensor sizes to see how crop changes your field of view.
If you want to shoot video with this lens, the Panasonic GH-series bodies on its compatible list, such as the Panasonic Lumix GH6, are the ones to look at first. I'd still read the Video guide before you buy.
