The 60-250mm is a fantastic lens. Not as fast AF as the Canon and Nikons maybe, certainly not Olympus (aren't they faster?). But the image quality is great, and the lens feels very good to use. The only lens I would go for instead is the 50-135mm f/2.8. The same things as with the 60-250mm, only brighter/faster. But it doesn't have the reach.
The Sigma 8-16mm is a great lens for the K-5. I have one, and it works great. Extremely wide, I also had the 10-20mm before, but sold it due to financial issues, but also a good lens, but doesn't draw bright light sources beautifully at all, actually very badly IMO (http://netrex.deviantart.com/art/Breaking-the-Snow-77529148). I don't have any good examples for the 8-16mm yet, it's been a dry spell for me, photography wise <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='

While the Pentax 60-250mm f4 is a good lens, it is not very fast in AF and has that Sudden Death Motor too... So if one wants a lens like that, I would suggest to rather look at for instance a combination of Canon EOS 60D and EF 70-200mm f4 L IS USM. Faster AF, lighter and even a bit cheaper. The Sigma 8-16mm is great on any APS-C camera.
