Fair enough!
And, as I thought, the performance of the Sigma comes as no
surprise to some of the more experienced on PDML!
It reduces the number of choices I have to make so, ultimately,
makes my life easier: I'll stick with the Pentax glass when it
matters. (For "snapshots", the Sigma, particularly the AF, is
handy so I'll probably still use it then.)
Thanks for the feedback.
