I have to agree with most of Uncle Vanya's choices, I also agree that the FA 77 is probably the best, if the narrower FOV bothered you on the 70, it would probably not work for you.
I would definitely agree on the DA* 50-135 as it is an amazing lens! For a budget choice, I would say a DA 17-70 that still has a good SDM, (Available new with warrantee also,) that is a nice all around shooter.
I have even gotten nice results with my SMC DA 40 F2.8 Limited for groups of two plus a baby as long as they don't mind you up close. Any modern and many older lenses in the 30 to 135mm focal length can get great images depending on what your style of shooting is. Go for a limited or a Star* lens and your IQ will hold up to pretty much any style.
Go to the Pentax deals thread and McBains Camera in Canada has the DA*55 for under $410 USD shipped New!
