State of the Art: Hands On: Zeiss ZF Macros for Nikon: “I’ve been shooting lately with two new Nikon F-mount Zeiss lenses, the ZF 100mm f/2 Makro-Planar T* and the ZF 50mm f/2 Makro-Planar T*. (I love it when they spell macro that way.) As you’d expect from a Zeiss-made optic they are both simply razor sharp, and are also impressively heavy, in these days of featherweight zooms, due in part to their full-metal barrel. No, they don’t have autofocus–nor do any of the other ‘premium’ manual-focus lenses Zeiss is making for Nikon F, Pentax K, and M42 (threaded) mounts–but I haven’t really missed it.”
