Canon’s new RF 85mm f/1.4 portrait lens sits right between the compact f/2 option and the huge f/1.2 flagship. If you care about how your RF setup balances on a gimbal, how clean your files look at wide apertures, and whether a lens really earns a premium price, this one deserves attention.
Coming to you from Christopher Frost, this careful video walks you through the new Canon RF 85mm f/1.4 L VCM lens in a way that makes its role in the RF lineup clear. Frost starts with the basics: a full frame portrait prime that matches Canon’s other VCM lenses in size and layout so you can swap lenses on a balanced rig without starting over. You see the control, focus, and aperture rings in use, including how the aperture ring is smooth and lockable but only fully functional in video mode on the newest RF bodies. Autofocus gets a real workout, with Frost showing how quickly it locks on and how little focus breathing you see during pulls. He also points out that the lens skips in-lens stabilization, which matters if you rely on handheld video or bodies without strong in-body stabilization.
From there, the video moves into sharpness testing on a high resolution full frame body, using the Canon EOS R5 with in-camera corrections turned on. At f/1.4 in the center, sharpness and contrast are already strong, with no obvious purple fringing, which is not a given at this aperture. When Frost stops down to f/2 and f/2.8, you see subtle gains in contrast and a brighter frame as vignetting drops. Corner performance is a pleasant surprise, with detail that holds up well even wide open once you look past the heavy vignetting.
The video does not stay on full frame only. Frost mounts the lens on the Canon EOS R7 and uses its dense APS-C sensor to push the optics harder. Wide open at f/1.4, sharpness in the center is only moderate by his standards, and you can see that the sensor is asking a lot from the lens. Stopping down to f/2 brings back the crisp look you saw on the R5, and the corners track the center closely. He also checks distortion and vignetting with corrections off, showing a touch of pincushion distortion and very strong vignetting at f/1.4 that ease at f/2 and f/2.8. Close-focus performance is the first clear weak spot, with soft results at f/1.4 that only really sharpen up by f/2.8, so you see where you would need to adjust your working aperture at tighter distances.

Frost also spends time on rendering and comparisons, which is where the video becomes especially helpful if you are trying to choose an 85mm. Side-by-side shots with the older Canon RF 85mm f/1.2 lens show that the f/1.2 still gives a slightly creamier, more blurred background, but the difference is smaller than you might expect. You see how the new lens’ bokeh looks smooth and controlled, with only some cat’s eye shapes toward the edges that are normal for this type of optic. Frost notes that physically larger lenses often have more complex optical designs, yet this relatively compact f/1.4 still offers high contrast and clean detail at typical portrait distances. He also compares it in size to the smaller Canon RF 85mm f/2 macro lens, which gives you stabilization and closer focusing but less speed and a different use case.
Context within the system matters, and Frost does not ignore it. He calls out the Canon RF 135mm f/1.8 L lens as the sharper choice for pixel-peepers, especially at closer distances, and mentions that big spenders focused only on stills might still lean toward the high-end 85mm f/1.2 options, including the defocus smoothing version with its extremely soft background blur. You see where this RF 85mm f/1.4 L VCM sits instead: a premium portrait lens built to serve both stills and video, with fast autofocus, low focus breathing, matched size with the other VCM lenses, and very strong sharpness on full frame if you stay mindful of its close-up behavior. The price is not small, but the video makes clear that you are paying for a specific blend of performance and handling rather than a simple spec bump. Check out the video above for the full rundown from Frost.
