I have a question regarding the Sigma HSM which i'm struggling to find a definitive answer for online.
I have a Nikon D3100 which requires the lenses I buy to have the motors built in. Can anyone confirm whether the HSM element of Sigma lenses covers this requirement? I'm specifically looking at this lense:-
Sigma 70-200mm f2.8 DG OS Lens for Nikon AFD - 589955 - Jessops - Lenses
Which states this:-
EDIT - I've just found this which seems to confirm compatibility if i'm reading it right:-

HSM with Inner Focus
This lens is equipped with a Hyper Sonic Motor (HSM) for fast and quiet focusing. As focus and zooming are both internal mechanisms, the lens does not rotate or change size at all during focusing or zooming. In addition Full Time Manual Focus allows you to override the AF motor simply by twisting the focus barrel manually.
