Can't believe I'm selling this - the highest performing wide aperture lens ever. It is stunning. Just updated to a 50-150 and have a 35 1.4 so know this is gonna sit at home hence the sale. Owned by me from new. Cost a staggering amount just over a year ago. Boxed with all the bits you'd get new. Glass great. Just an amazing lens. The attached tear sheet was photographed wide open using focus tracking in super-flat light btw.
