Originally posted by pres589 Would be neater if Tamron was still at least somewhat committed to producing new lens in k-mount. Making a big assumption, I think they're going to continue production of the VC variant of the 17-50, which optically doesn't seem quite as nice as the older 17-50 that this thread is about. They probably make more money on those and it's a more recently developed product.
If I didn't already have an 18-135 I would pounce on this deal. I can't rationalize owning both.
Way it seems to be going for K mount...
This lens would be a better fit if you needed the speed of the lens.. since it is f/2.8 from 17-50 throughout. Plus that extra mm at the wide end is considerable if doing landscape work.
That said, I'd still go after the Sigma 17-50mm compared to this one.. unless this one was really dirt cheap as the Sigma tests better on pretty much everyones review of it (I've scoured the web
) overall.
