This is about the cheapest way to get a faster range between 18-135
but its still significantly more than the new 18-135 WR which in itself is pricey in comparison to others
It is a bit like comparing apples with oranges though.
Throwing some numbers, all from the same store as the OP noted with occasionally odd pricing
single lens convenience
Pentax 18-135 DC WR = 799 AUD
Sigma 18-125 (HSM OS) = 407 AUD
Sigma 18-250 (HSM OS) = 682 AUD
twin kit same f-stop
Pentax 18-55 mkII + 55-200 = 300(?!) + 261 = 561 (non WR)
Pentax 18-55 WR + 55-200 WR = 277 + 499(?!!) = 776 (WR version)
Sigma cheaper and heavier of course.
at 2.8
Tamron 17-50 (non VC) = 549 AUD
Sigma 18-50 = 501 AUD
Sigma 50-150 = 853 AUD
2 lens total = about 1,400
Pentax 16-50 = 1,254 AUD
Pentax 50-135 = 1,359 AUD
total = about 2,600
I suppose it all depends on how much money / LBA you have been blessed with.
