Lens advice for a maybe Pentax newbie

Hi there.

I am currently an Oly user thinking of changing to a K5. Most of my photos are wildlife (birds especially) and landscapes. I have read some fantastic reviews of the K5 but have not yet identified any longer zoom lenses which command good reviews. The longer zoom lenses available all seem to have focus issues at the longer lengths. The lenses I have been looking at include:
Sigma 120-400m
Tamron 18-270mm
Tamron 18-200

Can anyone using Pentax DSLR let me have views about which longer zooms (200mm or bigger) perform well?

Thanks in anticipation.
E-30, 14-54mm, 50-200mm, EC-14,
C770, FL-50, Lightsphere
