Is the sony fe 50mm f 2 5 g good for video?
Not really, not as a first pick for video. The 50mm f/2.5 is a standard prime with autofocus, but it isn't stabilised. On full frame it frames as a plain 50mm, and on APS-C it becomes roughly 75mm, which is too tight for most vlogging shots. The video guide recommends a wide lens, around 16-20mm full-frame equivalent at arm's length.
If you want Sony FE glass for video, look at the Sony FE PZ 28-135mm f/4 G OSS, a large power zoom built for video. If you want a wider zoom to start from, the Sony FE 24-50mm f/2.8 G is the other option here. Whichever you choose, plan for sound from the start, as the audio notes explain.
