Zeiss Otus 85mm f/1.4 APO-Planar (about $4490) for Nikon or Canon. THANK YOU for using this site’s links to pre-order.
Now up in Guide to Zeiss: my in-depth review of the Zeiss Otus 85mm f/1.4 APO-Planarwith 29 pages of coverage.
Zeiss spared little effort with the Otus 85mm f/1.4 APO-Planar. Six of 11 elements have special glass types (chromatic correction) and one is aspheric, so 7 of 11 elements are “special”. The whole thing is oversize, which generally means that it can be manufactured reliably (an optical design can be superb but too difficult/expensive to manufacture). The results are the most gorgeous images I have seen on any camera.
