reviewswhat are people saying

"As far as the noise, I can tell you I don't hear a thing but the band and the party when I shoot. This is a fast sharp lens. A great addition to any pro wedding photographer."

"i love this lens for general detail pictures for weddings, whether it be a bouquet or a church. the 1.8 makes for some really awesome and creative natural light pictures."

"The large filter size is a bit of a problem. They can be very expensive or hard to find at 82mm."

The firmware of the Sigma is outdated, you can have it updated by Sigma when you return it. Then it will work like a charm.
