In addition to a 2.8 24-70 this is obviously not the same dive or the same microcontraste nor obviously the same opening. But if he does not play in the same court on the D700 is a very satisfactory telephoto zoom, great dive up to 200 mm, well contrasted with sufficient brightness, good construction and ergonomics. Moreover light enough not to clutter louse marauding when weight is a andhicap. Excellent value for money.
