Ready for a Prime lens

What Prime lens would you suggest for my Sony a6000. I'm presently using
the kit 55210. I'm wanting a walk about lens.
thanks

I have owned the Sony Sonnar 24mm and it has been my default lens on my A6000. I cannot say enough good about this lens. It is an amazing lens.

Other viable options are Sigma Art lenses (19mm and 30mm) and Zeiss Touit lenses (32mm) as walk about lenses. I haven't owned them but I have read good reviews about the optical quality.

I got the 20mm f/2.8 pancake lens and I love it. It's VERY sharp and focuses very quickly. Another option could be the 28mm f/2, but it's $100 more expensive than the pancake.
