Sigma EX DG APO 500mm F4.5
This lens is the only true and capable lens for 500mm for Pentax K mount that one can purchase as new in Europe. It took me quite some time to get it - could have saved a few bugs still but did not want to wait any longer. Yet I did not experience TCs intensively but own the Kenko 1.5x SHQ, the Sigma 1.4x and the Pentax 1.7x... we'll see what is achievable...
Until now I shot more/less long distance and mostly birds with it - light is almost no issue - also in the dark winter period over here - as the K5 keeps noise at low level anyway.
If you want to view some of my recent shots:

Guess, for CaNikon you get slightly better resolution and sharpness at wider open apertures BUT, at this price tag and with this weight I know already now the combination K5/K-r/K-x plus the Sigma 500/4.5 is unbeatable.
Will edit this review when experiences sum up...
Update 20FEB13:
I'm still happy with my 500/4,5...!
A few shots loaded on flickr - 1st one was shot utilizing the Kenko SHQ 1.5x Converter

Update 23MAY13:
Since I own a K5 IIs it's even more fun with this lens... the shot of the European wryneck was taken by utilizing the Sigma 1.4 TC...
