After a month of testing on the Zf, Z8, and the 61 megapixel Leica, Voigtlander’s 90mm f2 APO might just be the sharpest lens I’ve used, but is it too sharp for me? That’s what I thought when shooting in colour, then I tried monochrome.  The reality rendered by a lens this sharp can be confronting, our imaginations need more room to breathe.  But reality’s stranger than fiction.
