Canon RF 50mm f/1.4L VCM review: This ain't your daddy's nifty fifty

The Canon RF 50mm f/1.4L VCM isn't just a key member of Canon's lineup of hybrid lenses, it also completes the trifecta of RF nifty fifties – sitting between the budget RF 50mm f/1.8 STM and the top tier RF 50mm f/1.2L USM.

Everyone has been waiting for the Canon RF 50mm f/1.4L VCM, which has traditionally hit the price / performance sweet spot for 50mm shooters. However, with this hybrid optic, Canon has gone even further to make this a unique proposition for those who shoot video and who want a uniform range of interchangeable primes.

Not only is there an Iris ring to manipulate aperture, the VCM autofocus is snappy and near-silent, and the 50mm f/1.4 shares the same filter size and broadly the same weight and dimensions as the other f/1.4 hybrid primes – meaning you can easily share filters across the range, as well as cleanly swap without having to massively recalibrate gimbals.

For crop sensor shooters, the Canon RF 50mm f/1.4L VCM has an equivalent focal length of 80mm – making this a perfect portrait prime for RF-S bodies, especially if you want a weather-sealed companion for something like the Canon EOS R7.

This is every inch the L-series optic that the red ring would suggest. Here's how it performs and compares to Canon's other nifty fifties.

Canon RF 50mm f/1.4L VCM: Price

The Canon RF 50mm f/1.4L VCM carries a retail price of $1,549 / £1,499 / AU$2,429.

Thar places it between the top-tier Canon RF 50mm f/1.2L USM at $2,599 / £2,449 / AU$4,099 and the Canon RF 50mm f/1.8 STM, which at $239 / £219 / AU$389 is the most affordable native lens in the RF lineup.

Another option, if you want a similar focal length and speed but without L-series performance or weather sealing, is the Canon RF 45mm f/1.2 STM – a brilliant budget alternative that clocks in at $469 / £479 / AU$699.

Canon RF 50mm f/1.4L VCM: Design & Handling

As noted, the Canon RF 50mm f/1.4L VCM is part of the brand's range of hybrid primes for the R system, which includes the RF 20mm f/1.4L VCM, the RF 24mm f/1.4L VCM, the RF 35mm f/1.4L VCM and RF 85mm f/1.4L VCM.

This outfit of video-friendly primes boast uniform size, weight and filter threads for harmonized handling and gimbal performance. As such, in the hand (and on the body) the the Canon RF 50mm f/1.4L VCM is virtually indistinguishable from its siblings.

They share the same 76.5 x 99.3mm size and 67mm filter thread, and largely the same weight with the 20mm at 519g, the 24mm at 515g, the 35mm at 555g, the 50mm at 580g and the 86mm at 636g.

This obviously achieves the aim of making them easily interchangeable for use with gumbals, filters and focus system, but it does mean that – end-on, at least – trying to pick the right one out of your camera bag is pretty impossible.

You'll probably want to label the front and rear caps with the focal length to distinguish them in the field. Likewise the lens hoods all fit each other so, unless you know the difference between EW-73G and ES-73 of the top of your head, you may run into issues differentiating them.

Unlike some of the other hybrids, the 50mm doesn’t have a rear filter holder – although this is more of a necessity for wider focal lengths (where front filters are liable to cause vignetting).

Again like its stablemates, it features a large focus ring, control ring and an Iris ring that can be engaged by an Iris switch. The Iris can be left at its ‘A’ setting, where aperture is set on the camera body, or manually rotated to a set value from the lens.

This works in video mode on all EOS R cameras perfectly, but for stills it only controls the aperture on cameras launched in 2024 onwards. (Canon previously told me it would like to expand compatibility further to "key" camera models in the future, but at this stage I don't expect backward-compatibility.)

Like Canon's other 50mm options, there is no optical stabilization in this lens – which means, if you need shake compensation, you'll need to pair this with an image-stabilized body. Though, in fairness, you're probably going to be using a pro lens like this on a pro body that does have stabilization, so this isn't really an issue.

Canon RF 50mm f/1.4L VCM: Performance

The Canon RF 50mm f/1.4L VCM employs separate USM and Voice Coil Motors, with the VCM driving heavier groups of glass elements inside the lens, resulting in a blisteringly fast autofocus operation that is also smooth and whisper-quiet.

One of the best features on this new lens is its super wide f/1.4 maximum aperture, which sucks in loads of light – handy for shooting in challenging illumination and keeping your ISO to a minimum, perhaps at a gig or concert, or even shooting stars for astrophotography.

It's also useful for blurring the backgrounds of portraits, as the wide aperture will create a super shallow depth of field, while the 50mm focal length provides a natural perspective, making this an excellent portrait lens for half- and three-quarter-length shots.

In terms of the bokeh – the quality and characteristics of the out-of-focus elements – like some of the other hybrid primes (particularly the RF 85mm f/1.4) the Canon RF 50mm f/1.4L VCM has quite swirly, vortexy, Petzval bokeh when shot wide open.

This reveals itself in busier backgrounds and can be very pleasing – but it can also quite distracting, if it's not an effect you're looking for, so just be aware of this characteristic if you're intending to shoot at f/1.4.

Speaking of the aperture, it’s worth noting that the more expensive and much larger RF 50mm f/1.2L has a maximum aperture that's only a third of a stop brighter. The bokeh is definitely smoother, and not quite so Petzval-y, but I think many shooters will be happy saving a considerable amount of money – not to mention bulk – going for the f/1.4 lens.

I was impressed with my shots taken on the 50mm f/1.4L. The center of the lens is pin-sharp, even shooting wide open. Comparing the in-camera JPEGs with the RAW files revealed a minor vignette at f/1.4, though this was pretty much imperceptible by the time I closed it down to f/4.

Aside from the minor vignetting, though, the corners of the frame are optically sound and there's no digital manipulation happening here – unlike my experience testing the RF 24mm f/1.4L, which relies quite heavily on in-camera tricks to push and pull pixels around correct distortion and remove quite a serious vignette from the RAW files.

General video performance with this lens is excellent. Autofocus is fast and faithful, focus breathing is incredibly well controlled, and manual focus is smooth and consistent – though some will lament that this is a fly-by-wire focus ring rather than offering true physical focus with hard stops.

Canon RF 50mm f/1.4L VCM: Lab results

We run a range of lab tests under controlled conditions, using the Imatest Master testing suite. Photos of test charts are taken across the range of apertures and zooms (where available), then analyzed for sharpness, distortion and chromatic aberrations.

We use Imatest SFR (spatial frequency response) charts and analysis software to plot lens resolution at the center of the image frame, corners and mid-point distances, across the range of aperture settings and, with zoom lenses, at four different focal lengths. The tests also measure distortion and color fringing (chromatic aberration).

Sharpness:

Center sharpness is nothing short of awesome, even wide open at f1.4, and remains so right through to f/11. However, you don't need to look too far off center to see a hefty reduction in sharpness at wider apertures. You really need to stop down to f/5.6 to get consistent sharpness across the whole frame.

Fringing:

Fringing is very well controlled at all apertures, never getting close to being visible in real-world shots.

Distortion: 0.62

The lens produces a touch of pincushion distortion, but not enough to be distracting.

Canon RF 50mm f/1.4L VCM: Verdict

The Canon RF 50mm f/1.4L VCM is interesting, because in many ways it's a more compelling lens than its bigger, bulkier, pricier f/1.2 brother.

Certainly for video, it's a no brainer. The 50mm f/1.2L USM is eminently impractical for videography due to its sheer size and heft. The 50mm f/1.4L VCM is infinitely more practical due to it being smaller and more compact, having a dedicated Iris ring, excellent focus breathing suppression and straightforward adaptability for follow focus units.

For photography, you pick your poison. Personally I would opt for the 50mm f/1.2L USM because it's bit more bokehlicious, a pinch less Petzval-y, and just that little bit faster when shooting in tough lighting. But it's close – and for most people, probably not worth the extra grand.

The rendering of the Canon RF 50mm f/1.4L VCM is beautiful and the difference in the shallowness of depth of field may be imperceptible to most. It's also, and I cannot state this enough, much smaller and lighter, making it way more practical – particularly on smaller and RF-S bodies.

While it's certainly a shame that the Iris ring only affects aperture when shooting video if you're using a pre-2024 camera, I don't think this is as much of an issue as others might.

Unlike, say, Fujifilm or Leica lenses, the RF system has never been built around manipulating the aperture using a ring. So the fact that it universally works for videography (where it's a much more fundamental feature) and isn't supported across the range for stills (where it's just a luxury) doesn't bother me.

For videographers, the Canon RF 50mm f/1.4L VCM is a no-brainer of a recommendation; for photographers, if you want more premium performance than the f/1.8 STM offers but don't want the price, size or weight of the f/1.2L USM, Canon has once again delivered the sweet spot optic you're looking for.

Alternatives

Canon RF 50mm f/1.8 IS STM – Canon's must-have prime is also its cheapest. It's nowhere near as advanced or optically impressive, but it's truly tiny and is also stabilized – helpful if you don't have a camera with IBIS.

Canon RF 50mm f/1.2L USM – The first ever L-series RF prime lens, the 50mm f/1.2 is huge, heavy and a low-light monster – but it's also a heck of a lot heavier, isn't stabilized, and is too chunky to be a go-to video lens.
