Seriously interested in a new series of these lenses from Sigma. It's really something of a very high quality. Before that, I thought to take a fifty dollars. I tried both Canon and Sigma, they all hit by. This one arrived right away with no problems. Excellent sharpness. Almost does not spoil the geometry. Small aberrations, but it is treated. Not far from a waste of money. Itβs nice to hold in your hands, the focus ring moves very smoothly, the focus is easily corrected after the machine, if you suddenly need it. If Sigma continues their creativity in this series, then it makes sense to look at them further. Very nice glass.
