This is one of the sharpest and fastest lenses with the oiliest side I've ever owned. For a while I also owned Nikon 35mm 1.4 AI, Nikon 35mm 2D, Nikon 35mm AF-S 1.4G and Sigma 35mm 1.4 Art lenses; I currently have a Canon 35mm 1.4L II for my Canon which is over twice the price of the Tamron. This Tamron lens surpasses them all in every way. And considering the price, that's not a problem. Buy this lens if you want the ultimate 35mm f/1.4 autofocus experience. Maybe the Sony Zeiss lenses are sharper, but of course they're more than three times the price of the Tammy.
