i've been sticking to primes ever since i got my k7 but i feel like i need an all-around zoom lens for travel and such.
17-70 seems like a great range since it's wide enough and long enough for many situations. also, $500 is my limit and the DA 17-70 fits right in.
so why don't i go out and buy one? well, SDM-only is not ideal. also, if there was a WR version for under $500 i'd be all over it. in fact, if it was over $500 (but not by much) i'd probably be all over it. but, as we all know, there isn't one.
sigma f2.8-4.5 and future f2.8-4 are also an option but for the same price i would rather just go with pentax.
another option is the DA* 16-50mm f2.8, which is a very nice lens, but a bit too much for me with regard to size and cost. also, i would like to have that 70mm range.
at the other end of the spectrum, there are 18-200mm and 18-250mm lenses. the tamron 18-200mm seems like a great value at only ~$250 but it's an f6.3 lens.
so... what to do... what to do... any advice?
ps, sorry about the "yet another 17-70 thread"
