Of all the eight 85mm lenses we’ve ever tested on our optical bench, the Zeiss Otus APO Planar T* 85mm f/1.4 ZF.2 (Nikon mount) and ZE (Canon mount) lenses are the largest, heaviest, and most expensive. Compare our Nikon mount’s street price of $4,490 to Sony’s 85mm f/1.4 Carl Zeiss Planar T* ($1,698, street). Why the gaping disparity? In part because, like the 55mm Otus before it, this lens—the second focal length represented in Zeiss’s ultra-premium Otus line—includes some pricey elements. One aspheric element boosts sharpness, especially at the edges, and several low-dispersion optics control chromatic aberration. It’s also a gorgeous precision instrument.
