Canon RF 50mm f/1.8 STM Lens (Canon RF) Review

The Canon RF 50mm f/1.8 STM is a compact, affordable nifty fifty for Canon's RF-mount mirrorless system. At just 5.6 ounces and $239, it offers a classic 50mm focal length with a bright f/1.8 maximum aperture, making it a practical choice for portraits, street photography, and low-light shooting on full-frame RF bodies. The lens includes an STM motor for smooth, quiet autofocus and a customizable control ring, a feature typically reserved for pricier RF glass.

The optical formula incorporates an aspherical element and Super Spectra Coating to help control aberrations and flare, while a seven-blade rounded diaphragm should deliver pleasing bokeh. The lens focuses down to 11.8 inches with a 0.25x magnification ratio, offering some close-up versatility. Its 43mm filter size and minimal footprint make it an unobtrusive walk-around option.

As an entry-level prime, the RF 50mm f/1.8 STM slots below Canon's f/1.2 L-series options but provides an accessible gateway to fast prime shooting for RF users on a budget. It lacks image stabilization, so you'll rely on in-body stabilization if available.
