DA21 is, unfortunately, the weakest of all DA Limited lenses. It is not bad, but it is not brilliant like the DA15 or DA70 either.
I was always hoping Pentax will wake up and deliver a 24mm / f2 lens on par with best Limiteds, one that could become a centre of gravity of all Limiteds.
To me DA21 looks like a decision made by some bureaucrat in Pentax HQ, who could not decide whether Pentax should issue a really good 28mm equivalent lens (or 18.5 in APS-C), or a kick @ss 35 mm equivalent lens (24mm in APS-C), and decided to go middle way, middle value, with no flair.
Ricoh's GR lens, of course, is amazing, and even more so because it is
premium coated on all sides of all elements, optically refined to sit
close to sensor and delivers it best light possible.

I am almost convinced. If I get a good selling price for my DA 21mm I think I will get me a Ricoh GR. Then I could take wide shots and do my beloved macro stuff with the 100mm WR on the K-5 at the same time. :-)
DA21 has its value for the K-mount DSLR, and I'd think twice before selling it. More because the GR is a separate camera altogether, and usually when you take a DSLR, you will not use the GR. And vice versa.
Treat them separately.
