Sigma are a 3rd party lens manufacturer who make lenses for multiple systems. As far as I can tell that lens was made for Nikon and Canon at least.
Therefore if it has a Nikon F mount it will fit, if it doesnt, it won't.
EDIT: apologise, it seems I misunderstood the question and you were referring to firmware. Didn't mean to teach a granny to suck eggs!
