Hi all. Am new to this forum and must say there is a lot of stuff here. Dont know where to look first. Need a little imput from anybody about 2 lenses. I shoot motorcycle races and need to decide between these two.Nikon 80-400 AF-S VR and Sigmas 50-500 EX.I am leaning to the Sigma as i understand it will focus faster then the Nikon.Am i wrong ?Thanks in advance. AS soon as i can will try to post some photos from my attempts. Am using Nikon D-70.

I personally would go for the VR. I have a Sigma 80-400 EX OS (Sigma's version of VR) and it is amazing. It has two modes, one for vertical and horizontal movement and one just for hoizontal...which is designed for panning. You can hand hold at the long end of the focal range and still get very sharp images...my two cents.

I don't believe the Nikon 80-400 comes in AF-S - Hence The Sigma 50-500 with 'HSM' is slighly faster in focus. Also the 50-500 is also sharper according to the MTF's results from the D70 on Photodo:

IMO in fast paced action you don't need VR as much and the 50-500 gives you more reach :idea:
