Sigma 70-200mm f2.8 APO HSM II for Pentax K7

[bdparker]

Has any Pentaxians tried the Sigma 70-200mm f2.8 APO HSM II on a K7 yet

does the OS & HSM function properly?

I am looking at getting this or the Tamron equivelent (but I have found a special deal on the Sigma)

I have 2 Sigma Lenses with HSM, both fantastic - silent & quick enough, one lens has OS (17-70) but I turn it off & use the incamera shake reduction as the only time the lens OS in theory would be better is for longer lens lengths - whether @ 200 the incamera is outperformed by the OS in lens is probably debateable, I've not read any comparisons.

Wish I could buy a Sigma 100-300 f4 with HSM, as this is the only failing with my 100-300 f4.
