I’ve had little time to shoot the Leica 180/2.8 APO-Elmarit-R (see previous entry), but I did manage a few A/B comparisons on my Canon EOS 1D Mark III. At some point I’ll present some images, but for now suffice it to say that the Nikon 180/2.8D IF-ED needs f/8 to look less good than the Leica at f/2.8 (excepting depth of field). If you shoot Canon and you’re looking for the ultimate (handholdable) 180mm, the Leica is your beast (the discontinued Canon 200/1.8 is incredible also, but huge and heavy). To shoot Leica (or Nikon) on Canon EOS, you’ll need to use an adapter and shoot with manual focus, but that’s life. Leica lenses cannot be used on Nikon bodies, so if you shoot Nikon, hope that Zeiss adds a 180/2.8 Makro-Planar to the ZF lineup.
