The first time I touch this
Canon EF 50mm F1.8 II
lens I feel it most like a toys than a lens. It's a light-weight and plasticky if compared to other Canon 50mm type. But if you have a limited budget to buy a large aperture lens, this is a perfect lens you must have in your collection. The large aperture at 1.8 make it easier to capture an image in low light condition.
I captured a lot of images with this cheap lens and I feel satisfied. The bokeh and sharpness at wide open is still acceptable. You will get a sharper images if you stop down the aperture.
