If you need the constant 2.8 aperture get the Tamron but its a bit big and heavy
Just to give another perspective, I don't find the Tamron 17-50 to be big or heavy at all. The Pentax 16-50 is big and heavy. The Tamron 28-75 is bigger and heavier than the Tamron 17-50, but still not particularly big or heavy. I am actually quite impressed with what Tamron was able to pack into the relatively small package of the 17-50/2.8. It's a great lens.
