Everybody, as they say, must have a fast fifty in their kit bag. Even if it’s on a crop-sensored camera, a 50mm offers a great compromise in size and weight while giving you a decently fast aperture. Which Canon 50mm lens works out the best for you? In this video, we take a look at the 50mm f/1.8 II(http://bit.ly/Can50mmf1-8ii), 50mm f/1.4 USM(http://bit.ly/Can50mmf1-4) and the 50mm f/1.2 L USM(http://bit.ly/Can50mmf1-2). But there’s a big price gap between them….which one should you buy?
