Your results are just excellent - love the details and colour.
Tamron have produced very fine lenses in each class for the price you pay.
I haven't tried the 17-50 yet, but something tells me it would be a fine contender to the DA* 16-50.
I have not tried the 17-50 yet either, but the lens that SEEMS to have a permanent home on my K-7 is the Tamron 17-35F/2.8-4.0 and I do have the DA*16-50.
Another thing that should be noted is that the service at Tamron is also excellent and they really do take care of any problems they encounter. It should be noted, That I have only sent one lens back and it came back perfect.
