I said it is large and heavy, but not impressive. Chalk it up to my copy, or the 6D, but I find my Olympus 12-60mm SWD quite a bit better, especially wide open. When I had it, I finally understood that much of the praise heaped on that lens is due to how old the design is (and so are the reviews) - the AF isn't really "silent" or "lightning-quick", the build is good, but not fantastic, and the IS seems outdated now. It still can produce excellent IQ at f/8, and great portraits on FF at 105mm and f/4, but for me it isn't worth the hassle. There are much better zooms, including the much-maligned Sony FE 28-70mm f/3.5-5.6 (that's a DAMN SHARP lens at f/8), that are lighter and smaller.
