Canon 50mm f1.8 EF

Canon EF 50mm f1.8 II Lens
This is the lightest EF lens of all at a mere 130g. Compact and high-performance, standard lens. Its Gaussian optics provide sharp delineation from near to far focusing distances. The color balance is excellent for a standard lens.

Used rarely nowadays but it great for portraits on a 1.6 crop Digital SLR. No USM but focuses fast and accurate. Cheap and cheerful lens.
