The lens receives pretty good marks in the review, though a few things such as the lack of weather sealing, size and microcontrast. Though the lens is remarkably sharp and the autofocus works well.
“Sigma’s 50mm f1.4 Art DG HSM is an exceptional lens. Starting with the design, it very much is in line with the company’s 35mm f1.4 Art optic. The outside feels and looks like something that Hasselblad might make. It feels just so great in your hands that you’d never want to let it go. In fact, if you’re a big fan of the 50mm field of view you might never want to give it up.”
