Is the nikon af s 85mm f 1 8g good for video?
The Nikon AF-S 85mm f/1.8G can work for video, but it's a specialist choice rather than an all-rounder. It's a telephoto-leaning prime, so on full frame it frames tightly, and it's a good fit for interviews, talking heads, or shots from across a room. It has autofocus, but it isn't stabilised, so handheld footage will show every wobble. Use a tripod, a monopod, or a gimbal.
If you vlog at arm's length, the Video guide recommends a wider lens, so this one will feel too tight. The Nikon AF-S 28mm f/1.8G is the wider prime on the same full-frame mount and is a better starting point for that kind of work. Whichever lens you pick, budget for sound, as the audio section explains. Audio usually matters more than the lens.
