Our take on the Canon EF 50mm f/1.4 USM


Pair your Canon digital SLR with this high-quality 50mm lens to capture crisp, sparkling-clear images. Its large maximum aperture of f/1.4 gathers lots of light to give you an ultra-bright view through your viewfinder, plus it means you can use faster shutter speeds to "freeze" moving subjects. This lens is also ideal for taking great-looking photos at twilight, or indoors without a flash. Its 50mm focal length also makes it an excellent choice for portraits and all-around picture taking.

Product Research


Overview: The Canon EF 50mm f/1.4 USM is a standard/medium telephoto lens featuring superb quality and portability. Two high-refraction lens elements and new Gaussian optics eliminate astigmatism and suppress astigmatic difference. Crisp images with little flare are obtained even at the maximum aperture. The Canon EF 50mm f/1.4 USM is an ideal lens to accompany a zoom when shooting in low-light conditions. It is the only lens in the Canon EF System line-up to combine the extra-small Micro USM and still provide full-time manual focusing.

Compatibility: The EF 50mm f/1.4 USM is an EF Canon lens which means it is compatible with all Canon digital SLRs (those that accept EF and  EF-S lenses, plus those that accept EF only; which would be the Full-frame EOS 5D Mark II), as well as Canon EOS film SLRs.

Lens Construction: The Canon EF 50mm f/1.4 lens features a lens construction with 7 elements in 6 groups.

Diagonal Angle Of View: This Canon standard telephoto lens provides a diagonal angle of view of 46°.

Ultrasonic Motor (USM): With the Ultrasonic Motor (USM), you can expect fast and quiet focusing capability.

Auto/Manual Focus: To shoot in Autofocus mode, set the focus mode switch on the lens to "AF". To manually focus the camera, set the switch to "MF", and focus by turning the focusing ring. The focusing ring always works, regardless of the focus mode.

Optional Accessories: You can attach optional filters to the filter mounting thread on the front of the lens. You can also attach an optional lens hood.

Product reviews from the Crutchfield Labs

This lens is ideal for taking great-looking photos at twilight, or indoors without a flash. Its 50mm focal length also makes it an excellent choice for portraits.

Bright and sharp

Written by Zak Billmeier, Video Producer, on 2/3/2012 3:38:00 PM

This is a fantastic portrait lens if you shoot with a Canon crop camera (60D, 7D, Rebels, etc). The 50mm focal length looks like 80mm on the small sensor.

The f/1.4 maximum aperture lets you shoot in dim rooms. It's great for grabbing candids at parties and weddings where a flash may be out of the question.

It starts getting sharp at f/2, and by f/2.8 it's quite sharp. Just an outstanding lens for a good price.

Focus is fast and silent. All Canon's "USM" lenses are.

It's a great "normal" lens on full-frame and film cameras. And it's fairly compact and lightweight.

If I could only have one lens for the rest of my life, this one might be it.
