After almost 25 years (the 70-210/f4 was discontinued in 1988), Nikon has introduced a medium telephoto zoom with a constant f4 aperture.
One hopes that this lens is a lighter, less-expensive version of the 70-200/f2.8; it could be a boon to many aspiring sports shooters looking to upgrade from consumer-grade lenses like the 70-300 without having for fork over two grand. The price tag is nonetheless steep, with an MSRP of $1,399.95 – add another $200 or so for the optional tripod collar (an unnecessary extravagance for this type of lens if you’re shooting sports).
Of course, how the lens looks on paper doesn’t tell the story; and for this lens in particular, the AF performance is something that will be crucial. Not all Silent Wave (AF-S) focus systems are created equal; there’s a world of difference, for example, between the 70-200/f2.8 and the 70-300/f4.5-5.6 lenses in this regard. If this lens does’t have pro-level autofocus, it really has no place in a sports shooter’s bag.
