I haven't touched a white lens in years and I just got my 100-400II but had no time to try it. Today a hawk posed for me. He was a little far away so the image is heavily cropped but it turned out ok. I will have to wait for the weekend for a real outing and for my Teleconverter to show up on Friday.
I am (slowly) getting back in the game!
As always C&C welcomed and encouraged.
