Canon EF 50mm f/1.8 STM
Crutchfield Customer Review (What's this?)
This tiny jewel of a lens works with all Canon digital cameras, both APS-C and full-frame. The focus is fast and accurate. Sharpness and color rendition are superb. The f/1.8 maximum aperture allows for excellent depth-of-field control with pleasant bokeh. The low price makes this lens a real bargain and a no-brainer.
