These lens are great, and not just for the price. They are well constructed, feel nicely weighed in the hand, and not plasticky. They are reasonably heavy, but I see it as an asset, since it makes it easier to hold the camera steady. The output has been consistently sharp photos. The only improvement would be to speed up focus a little bit, as these lens do seem to hunt on occasion in low light, but for the most part that is not an issue.
