EF 50mm
f/1.4 USM

The EF 50mm f/1.4 USM is Canon's medium-budget 50 mm prime lens that combines good image quality with a compact and lightweight form factor. It has a USM motor that allows manual override during autofocus operation but it's an older generation model that's a little slower and noisier than modern USM motors. The lens is solidly built but of the outer parts only the lens mount is made of metal. The very low f-stops available make this lens ideal for available light photography and portraits. Due to its high resolution at higher f-stops it's also suitable for landscapes (not so much on APS-C cameras where the effective focal length is 80 mm). Even wide open the EF 50mm f/1.4 USM has an impressive resolution but color fringes (both in focused and in blurred parts of the images) are a problem with this lens. Distortion is also an issue if the lens is used with a full frame camera. While corner shadow is present it does fade with higher f-stops and there is no curvature of the focal plane. The aperture shape is circular and creates even-looking bokeh.

The EF 50mm f/1.4 USM costs more than three times as much as the EF 50mm f/1.8 II but (unlike the high-end offering EF 50mm f/1.2L USM) is still affordable for most. The surcharge is paid for a better autofocus motor, higher built quality, a properly sized focus ring and of course a better maximum aperture of f/1.4 rather than f/1.8. I would have hoped that the image quality were also a step upwards but it's very similar to the EF 50mm f/1.8 II (which is probably good enough anyway). In real-life applications however the EF 50mm f/1.4 USM will likely deliver better images just for its superior focusing operation. If you are on a tight budget you'll be more than happy with the lower-cost offering but if you can easily afford it the EF 50mm f/1.4 USM will be a nicer lens to use.
