Title: Super lens
Review: After much research, I bought this lens about a month ago and I am loving it. This is my primary lens at the moment , however I do have a 50mm 1.8 prime as a secondary. This lens has a good weight and good build quality. 12mm is a nice wide angle with which you can accomplish some amazing compositions. There are a couple of things to be careful with, which are common with any wide lens - at 12mm and using on camera flash the camera will see it's own shadow cast by the lens - This is not a problem with a separate speedlight.
