Just to prove Gary wrong...
Nice shots!
Only joking, some good stuff there. Have to say I am surprised at your choice of lens for someone actually working a job rather than us lot having a bit of fun on the other side of the fence... still, if you get along with it then good hit!
You probably saw my two oppos down at the rallycross the other day... I was busy elsewhere last weekend, but I am sure we shall meet at some point!
