Originally posted by robbiec How dare anyone compare a Tamron to a Pentax Limited! It is like comparing a pair of rubber soled and imatation leather shoes bought in a Walmart weekend offer to a pair of bespoke Budapester shoes. It is apples and oranges. Pentax do not cater to my camera is big, my lens is big, i'm a serious photographer... Pentax have filled out a sub 135 format system that caters to the more discrete photographer, who does not need to announce their presence, who revels in the handling and ergonomics of a beautifully built, capable and quiet but also class leading K-3. To speak bluntly my friends, if you want brash, big, noisy, a statement in other words... F%£¥ off to the competition
Simple really.
It's all about the optics dude!
17-50mm outperforms the Pentax 16-50mm
90mm macro is well respected by all
70-200mm f2.8 is actually quite a good lens (it's not perfect but decent), albeit screw driven..try buying a decent 70-200mm f2.8 for under £600
Sure I grant you Tamron build is well it's "ok" for what is it and the price reflects that. Limited lenses have superb build, but how rough do you treat your gear?
I suspect quite a lot of Pentax users buy Tamron lenses, because they can actually afford them!
And most (not all of them granted) have nothing to be ashamed of optics wise either.
I mean we do take photos, so the lenses do matter..good optics and fair prices are a win win for the buyer
