reviewswhat are people saying

"This lens is light weight and very compact. It is fast enough for low light applications and is built like a tank."

"Great option for taking casual pictures of family and friends or for low-key urban excursions."

"It is small. Without a filter and hood, it matches the height of pentaprism and left side grip, which makes my *istDL really handy."
