With the 1.4X, you *may* get acceptable performance wide open, with

good performance *possible* one stop down, but only with the best

lenses, converters, AND matching; with the 2X, you will be lucky to have

decent performance by f5.6 (f11 effective). Probably better: the 1.4X on the

70-200 f2.8, which may perform well by an effective aperture of f5.6...
