Re: Really OLD thread, however . . .

TRUE!!!!!!!!!!!!!! Maybe one too many glasses of wine? Yes, 400mm it is. And 600 at f4 would be a better answer. Thanks for catching this screw-up.

Slight glitch in your calc:
200mm + 2X = 400mm + DX field of view = X 1.5 = 600mm equivalent.

Really OLD thread, however, a 200mm f2.0 with a 2x converter would be a 800mm f4.0 lens. Now put it on a DX camera, like the D7000 and you have 1200mm (equivalent) at f4. Yeow. Now you are playing with the big boys. Just dig deep, this ain't cheap!

The 2x converter could easily fit in a jacket pocket. Just don't try to market the shots, however!!!!!! You will run into serious copyright problems.
