I don't understand the OP because the Sigma is obviously better from 135-250mm - the Pentax has a clear disadvantage there.

But the real comparison will be with the 18-300mm Sigma - I'll be interested to see how it fares vs. any of the pentax consumer zooms.

the difference between a 300 and 250, just isn't all that much, I guess there might be a few shots that would be marginally better at 300mm. I'd be more concerned about the lack of IQ with the super zooms through out their range. Pentax managed to keep the centre up in the excellent range throughout the entire zoom range, the 18-250 might be excellent in a few spots, but for the most part is very good or good. The 18-250 is a good lens, just not a great lens. The 18-135 as a whole is a better lens and is a great companion to the 60-250. Taking those two lenses you just leave the 18-250 home. It has nothing to offer.

I had a super-zoom when I was newbie and used it once on a trip, then I left soon after that, and never look back.

OK< since this comes up often, I've put up another meaningless challenge. We all know the Tamron 17-50 is great and the Sigma 18-250 is so so, so can you pick out the Tamron 17-50 pictures, or the Sigma 18-250? Or the DA 18-135 or any of them.
