Viltrox AF 85mm f/1.8 RF STM ED IF Full-Frame Autofocus Lens for Canon RF-Mount, Black Review

The Viltrox AF 85mm f/1.8 RF STM is a third-party portrait lens for Canon's RF mount, offering a classic focal length and fast aperture at a fraction of the cost of first-party options. Viltrox has built a reputation for affordable glass that punches above its weight, and this 85mm slots into that lineup as a budget-friendly alternative for Canon mirrorless shooters. The lens features STM autofocus, extra-low dispersion glass, and an internal focusing design, along with a 72mm filter thread.

At $343, it's a straightforward value play for portrait and event photographers who want subject separation and shallow depth of field without the premium price tag of Canon's native RF 85mm options. The STM motor should provide reasonably quiet and smooth focusing for stills and video. It's a full-frame design, so it will work across Canon's RF lineup from the EOS R to the R5 and beyond.
