Thank you in advance

The Nikon 70-200 is an f2.8 lens so will work fine with a 2x (effectively becoming a 140-400 f5.6), the AF will be slower than without the 2x but will still be acurate. Canon make four different 70-200 lenses (f4, f4 IS, f2.8 and f2.8 IS), either of the f2.8 lenses will retain AF with a 2x but the f4 lenses with only AF with a 2x if used on a 1D.
