This is a bit off topic, geomez, but I think our inquirer here has had to make his decision by now. You have both the K-3 and the GR -- perfect! I've been pulling out my hair agonizing over the best present lens options for landscapes and cityscapes on APS-C. Very recently, a correspondent at the digilloyd.com site commented that without a doubt, he was getting better, sharper results from the 16mp GR at the 28mm effective equivalent focal length than he could with his no LP-filter 24mp D7100 at a similar field of view. The close integration factor between excellent lens and sensor on the GR seems to be the prevailing explanation here. Since he publishes few reader comments on his site, and he owns and uses both high end Nikon/Zeiss AND the little GR (his "Camera of the Year 2013", BTW), I can only assume that Lloyd is in full agreement, or close to it; or he wouldn't have published that email.
I have a new, still virginal K-3 here; but the lack of choice in modern primes of overall high performance, optimized for both sharpness border-to-border and a relatively flat field -- as well as being easily totable into the field -- is conspicuous, and frustrating as all get-out to me when considering the core FL's/fields of view for landscape: say, 24mm to 35mm FF-equivalents. I can't believe that the DA 21mm really fills the bill; it simple reflects other design priorities. I do have the DA 12-24mm, about which opinions are split when it comes to my application. I'm just about down to a used GR (assuming I can find a deal with time)... or, grudgingly, the 18-35mm/1.8 Sigma (28-1/2 oz. zoom -- Ugh!). Help! Have you any words of wisdom from the hands-on user perspective? From an effective-FF 42mm on up, I figure I'm in good shape with my present options.
