Okay, I'm down to the nitty gritty with a 70-200 and 1.4 tc for birding, not much reach but a diehard from within. Here are a few from over the weekend using this combo on a D3. All shot from my newly aquired Tracker Panfish 16'. I sure miss the 120-300 2.8 w/2x TC that I recently sold to pay a few bills. Thanks for viewing. Kevin P.
