Reviewing the Sigma 50mm F1.4 DG DN Art Full Frame Sony E-Mount Lens
I did 2 shoots with this new Sigma lens. The HLA (High-response Linear Actuator) mechanism for focusing gives you fast and silent autofocus. This lens has excellent low-light capability. It is extremely sharp wide open and at tighter apertures. Sigma let me borrow this lens for review, but did not have any input in the review.
