Picked up the Sigma 150 today. The guy gave me an offer I could not refuse! How about $495 brand new in box with authorised dealer warranty!
I had no doubt it would be sharp, and it is. My only concern was AF. Not for macro, but to use it as a tele lens.
Heres how mine AF's. Focusing from one distance to another is lightning - USM - fast if the distance is not far. That meaning roughly a distance of maximum 8 meters results in adequate/fast AF. Anything over 8 meters and it gets slow. The further the distance equals the slower it will AF. I kinda guessed that before buying/trying it.
My only personal issue with it is the hunting if it doesnt focus.
I remember some Cfn or Pfn on the 1dmkII to resolve hunting. Anyone remember it from the top of thier heads?
