Canon EF 50mm f/1.4 USM Lens Review by The-Digital-Picture.com

Ask a bunch of photographers what their favorite lens is – and you will likely hear the Canon EF 50mm f/1.4 USM Lens mentioned. It is sharp, small, light, inexpensive and with an f1.4 aperture, fast.

The first reason for the popularity of this Canon lens is image quality.

The Canon EF 50mm f/1.4 USM Lens is very useful for low-light indoor photography when a flash is not permitted, appropriate or desired. It works very well in a church or gym for example.

The Canon EF 50mm f/1.4 USM Lens is a good lens and focal length for full-body portraits. Keep in mind that when mounted on a 1.6x FOVCF body, you need some extra space to accomplish the full-body portrait. On these bodies, this lens makes a fine head/shoulders portrait lens as well.

The Canon EF 50mm f/1.4 USM Lens makes a good travel lens - especially for low light situations not easily handled by a general purpose lens. When space is tight and light weight is important, this lens might be the right one for you.

If you only need a 50mm focal length, this lens is a great choice. Overall, I think the Canon EF 50mm f/1.4 USM Lens is a good lens – and a very good value.

Pros:

• Excellent image quality when stopped down
• Essentially no lateral chromatic aberration
• Fast and accurate autofocus with full-time manual override

Cons:

• Distinctly soft and ‘dreamy’ at wider apertures (F1.4-F1.8)
• Bokeh chromatic aberration, most visible at wide apertures
• Vignetting at wide apertures on full frame (essentially disappears by F2.8)
• Somewhat susceptible to flare
