Beautiful, Sharp, Bulbous. Sigma 90mm F2.8 DG DN Review

Sigma is known primarily for budget-friendly third-party lenses. More often than not, the lower-priced options have been hit or miss. Thankfully that isn't the case with this I-series lens. It manages to strike the best of both worlds. The Sigma 90mm f2.8 DG DN Contemporary lens performs like a higher-end lens and comes in at a fraction of the price.
