I have a nikon 80mm-200mm 2.8 lens that I purchased in the 1993 era. I am considering upgrading to the nikon 70mm-200mm VRII. I am not sure if I will get better photo quailty. Most time I am shooting at 200mm range. I know the 70-200 is smaller and weighs less then the 80-200mm. Can someone give some opinions on these lenses.As always thank you in advance
