Hi everyone,
I am in dilemma in deciding whether to invest in a 70-200mm f2.8 vr ii lens to be used with my Nikon D90.
Or should I look into a sigma 70-200mm f2.8 hsm?
I am more a hobby photographer. Occasionally I take pictures for my church camp/functions, wildlife, outdoor and portraits.
Appreciate your inputs and advice.

Cheers
