My dad gave me an amazing Christmas gift this year. He passed his 70-200VR lens down to me to upgrade to a 200-400 I believe? He is insane. Lost his marbles I tell ya. Anyway, I haven't had a chance to do much with it, so last night I decided to see how it worked with the SB-600. I love the colors and how much contrast this lens produces. Love it. Can't wait to get outside and get some different shots. I am re-invigorated.
