#3(DA16~45) has been a pleasure to use since receiving it, along with the K20D, about a month ago. Quality images all, except a slight bit of f/4 softness although f/22 is surprisingly sharp. I shoot almost no architecture, so haven't noticed any distortion. Have to say I haven't noticed any CA, but haven't really looked for it either and sharpen very conservatively.
