In case anyone wonders:
I got the K20D with the intend to use the 18-55 II for WA, stopped down, and after the 40/2.8 later add the 21/3.2 and 70/2.4. But that day i used the 18-55 II, i realized i do like the convenience of a zoom downtown (And thus anytime).
So the 16-50/2.8 made sense since i had a 2.8 zoom on the 30D before (just always missing the 18-24 range), after a while of amost convincing myself the 16-50/2.8 is a bad one i came around and now, the more i use it, the better it seems to get, like it had to be broken in
the 16-50/2.8 now of course covers both the 21/3.2 and 40/2.8, and at 2.8 and smaller, it covers the 50/1.4, the 50-135/2.8 would also cover the 50/1.4 at 2.8 or smaller, it covers the 90/2.5 (while not getting as close i guess) and covers the 135/3.5 and the 70/2.4 i thought i wanted. (And it seems it does render beautifully for anything i like to and will be shooting)
So with a little bit of sense, i ruled out about every other lens Pentax makes or made, (the faster limiteds, 31, 43, 77, are luckily too pricey to even start with a purchasing plan, i don't need another macro and all the lovely ZK MF Goodness is well beyond reason in $$$)
I just didn't want to be blind sided by one i had not considered
Like someone here said, after next week i should be "happy like a fly on poop", a state i haven't been in since i bought the 30D (man did i love my EOS3), took me too long to pinpoint i disliked the body, not the lenses on it.
