Pentax is an absolute junk compared to Sigma's iteration.

A faulty copy? Or you cannot handle the lens?

I also had a Sigma 17-70, but sold it because of the yellow colour cast it produces.

There's a difference between biased opinions based on sentiments (e.g., "lens A is better because its produced by manufacturer X") and actual proof. Here is some proof below:

Comparison 2

Comparison 3

By the way, I'm loving the "nice rich colours" (?) of DA 17-70mm hidden behind terrible image quality. In any case, you can always edit the colour profile but can't make a lens sharper in PP. Increasing (micro) contrast in PP is not the same as actual sharpness captured by lens.
