a perfect "walkaround" Focal length for APS-C is 20 mm or 21 according to your question.
I like 15 for long exposure night scrape stuff. But I think it make people face looks funny, and (off topic) its build in hood is absolutely annoying me. Walking sometime running around 4-6 hours at night and hope that the hood will help protect the front glass if I accidentally bump into something? nope, it often retracted back unnoticed. not a fan of this type of hood. anyway, I like 20/21 mm focal length for general walkaround photo. I often take only a 20mm with me on trips, and may be a Gollarpod in back pocket. no camera bag, no lens change, no drama. That's my take.
since my fa20 is broken, I plan to get a 21 for my upcoming trip, but waitting with a "little little" hope to see if Pentax will show me a 21 wr version on CP+? I would love it so much, if somehow they did,
