Is the pentax hd d fa 24 70mm f 2 8 ed sdm wr good for vlogging?

I can't say for sure. This lens's page covers its focal range, aperture and mounts, but it doesn't address vlogging. The main thing to know is that it isn't stabilised, which matters for handheld video. Without stabilisation, you'll want a tripod, a gimbal, or in-body stabilisation on your camera.

On APS-C it frames like 36-105mm, which suits most talking-to-camera setups. The constant f/2.8 keeps your exposure steady as you zoom, and it gives nice background blur. If you're weighing what makes a camera good for video, the Video page covers that. For the lens side, see Lenses.
