Prime lens for EOS R system

The Canon RF 50mm f/1.2 L USM is a fixed focal-length prime lens built for the Canon RF mount and full-frame mirrorless cameras. It serves photographers who need a fast standard perspective for portraiture, street work or fine-art subjects.

f/1.2 aperture with no stabilisation

The lens opens to a maximum aperture of f/1.2 and stops down to f/16, gathering ample light for shallow depth of field and low-light exposure. Optical image stabilisation is not included, so steady handheld technique or in-body stabilisation becomes necessary at slower shutter speeds.

77 mm filter thread and 0.19x magnification

A 77 mm front diameter accepts standard screw-in filters for creative or protective use. Maximum magnification reaches 0.19x at the 15 inch minimum focusing distance, limiting close-up reproduction to roughly one-fifth life size.

Questions about this item

How do I decide whether the f/1.2 maximum aperture or the f/16 minimum aperture suits my shooting style?

The f/1.2 maximum aperture gathers the most light and creates shallow depth of field for portraits and low-light work, while f/16 provides deep depth of field for landscape or architectural detail.

What does the 0.19x magnification figure mean when I am framing a subject close-up?

At the minimum focus distance of 15 inches, the subject is reproduced at 0.19 times life size on the sensor, suitable for detail shots but not true macro reproduction.

What performance limits come from the Canon RF mount on this lens?

The RF mount enables a short back-focus distance that improves edge-to-edge sharpness and allows the customizable control ring to communicate directly with the camera body.
