>>4146540this lens if fucking awesome on my D810, I had splurged on a Sigma Art 50/1.4 and fell on hard times, I didn't want to believe it but my friend said I should sell it and get the 50/1.8D for like $50, and holy shit I felt so stupid after doing it, sure I was bummed about it, and tried to be super negative about it, but the images didn't lie, there was no tangible difference I could find except I could stop down to 1.4 which I never did anyway cause DoF was too narrow
