Standard 50mm f/1.4 lens for Canon SLR

The Canon EF 50mm f/1.4 USM is a standard focal-length lens built for Canon SLR cameras. Its wide f/1.4 maximum aperture suits low-light shooting and shallow depth of field. Two high-refraction elements and Gaussian optics reduce astigmatism for crisp results. A Micro USM motor enables quick autofocus with full-time manual override.

Upgrade from slower kit zooms

Photographers moving up from variable-aperture kit zooms gain a constant f/1.4 aperture across the frame. The jump is worth it when you need faster shutter speeds indoors or stronger background separation for portraits. The 50mm field of view matches human perspective on full-frame bodies. Buyers who want zoom flexibility or wider angles should look elsewhere.

Compact barrel with simple mounting

The lens measures 2.9 inches in diameter and 2 inches long, so it fits easily in a small bag. It mounts directly to any Canon EOS camera without adapters. The front does not rotate during focusing, making circular polarisers straightforward to use. Ensure the camera body supplies power to the Micro USM motor; older film bodies may not drive it reliably.

Questions about this item

What filter thread size does the 50mm f/1.4 lens accept?

The lens barrel measures 2.9 inches in diameter, so filters and caps must match that thread size.

How do I switch to full-time manual focus on the USM motor?

Turn the focus-mode switch to MF, then rotate the focus ring at any time — the micro USM motor disengages automatically.

When should the aperture blades or USM motor be serviced?

If the iris sticks at f/1.4 or the focus motor makes unusual noise, have a technician clean the blades or replace the micro USM unit.
