Is the pentax hd d fa 21mm f 2 4 ed limited dc wr good for street photography?

Yes, I think it's a good street lens. It's compact and weather-sealed, and street photography rewards a camera people don't notice. On full frame, 21mm gives you a wide view of the scene, and f/2.4 helps in dimmer streets and keeps more of the frame sharp. It isn't stabilised, so slower shutter speeds in low light will need care.

If you shoot full frame, the Pentax K-1 Mark II gives you the 21mm view as marked. On APS-C, the lens frames more like 32mm, which is a tighter, very usable street angle. Try the Pentax KP or the Pentax K-70.

Whatever you shoot, be open about it, smile, and delete a frame if someone asks. Our Street page covers the rules and manners.
