K10D Lens

I have a K10D and am thinking about buying a 135-400mm Sigma Lens for it, does anyone have one of these and are you happy with it.

Thanks Andrew.

Hi

Yes i have one and its really good. In fact a wildlife print i took was voted 2nd place at my camera club, taken with this lens. Now im using a K10 and with the motion sensor switched on and hand held its very sharp at the full focal length. Regards
