Yep.
Its about 18 months old,but it was upgraded recently when it went back for an image board problem...i havent pushed it since it came back,so it may be worth a go..
My 70-300 is nice,but needs careful use,part of which is keeping the iso down to help get sharp images(bit of a focus nazi
)
Ignoring the price difference,i am looking at the 300 f4,or maybe the 70-200 2.8...come on lotto
