The EF-M 32mm F1.Four STM was a straightforward lens to overlook when it was introduced, unveiled concurrently Canon’s all-new EOS R. Fairly how the EOS M collection will play alongside the newer R line stays to be seen, however its adopters have been clamoring for extra wide-aperture native lens choices for a while, so it’s good to lastly see a lens of this sort be part of the lineup. And at F1.4, it is the quickest lens within the EOS M system so far.

The third prime lens for the EF-M mount, the lens’s 32mm focal size gives a flexible equal focal size of 51mm in full-frame phrases on EOS M-series our bodies, and an aperture equal to an F2.2 lens on full-frame. As the one lens of its form within the vary, it ought to enchantment extensively to these already invested within the system, significantly portrait photographers who haven’t actually had an appropriate different as of but (at the very least not a local one).

It must also discover quite a lot of love from these capturing in low gentle, and it additionally is sensible for these desiring to seize nature who don’t want a lens with true macro capabilities. In brief, it has loads of enchantment.

Key specs

  • Focal size: 32mm (equal to 51mm in 35mm phrases)
  • Aperture vary: F1.4-16 (In 1/three stops)
  • Filter thread: 43mm
  • Shut focus: 0.23m (0.76ft)
  • Most magnification: 0.25x
  • Diaphragm blades: 7
  • Hood: elective (ES-60)
  • Size / Diameter: approx. 56.5 x 60.9mm (2.22 x 2.40in)
  • Weight: approx. 235g (8.3oz)
  • Optical development: 14 components in Eight teams

That huge aperture is arguably much more necessary right here, provided that that is solely the second lens within the secure to not be furnished with its personal picture stabilization system. This isn’t a characteristic we’d count on as normal on a lens of this type, nevertheless it wouldn’t precisely be misplaced when you think about that stabilization isn’t discovered inside any present EOS M-series our bodies (at the very least not mechanically). Its omission from the lens itself might be much less of a priority for anybody intending on capturing portraits, however these planning on utilizing it for static topics in sub-optimum gentle might need hoped Canon had discovered house for this.

Talking of not discovering house for issues, it’s a disgrace to search out {that a} lens hood isn’t included with the EF-M 32mm F1.Four as normal.

Design and dealing with

The general design of the EF-M 32mm F1.Four is in line with the opposite optics within the collection, which is to say good and understated. Its charcoal gray end completely enhances the EOS M50 physique I used throughout this evaluate, whereas its weight of 235g offers it some substance relative to its dimension when held by itself. The mix is simply as properly balanced within the palms as it’s to the attention, and the entire package deal will nearly match right into a coat pocket.

The streamlined barrel options a big, textured focusing ring, whereas the remainder of the casing has a matte end that’s clean to the contact. The general result’s maybe probably the most minimally styled lens within the line for the reason that (a lot smaller) EF-M 22mm F2 STM pancake lens. As with its siblings, there’s no focus-distance window or equal markings, and within the absence of an AF/MF change, alternating between autofocus and handbook focus must be achieved by way of the digicam.

It is solely the main target restrict change that bodily breaks the lens’ symmetry. We wouldn’t essentially count on such a lens to be fitted with one, however its inclusion makes some sense when you think about its 0.23m close-focusing restrict and broad vary of potential functions. This two-mode management permits you to both use the complete focusing vary or to work between 0.5m (1.64ft) to infinity, and it’s comparatively flush with the remainder of the barrel and considerably stiff. This, along with its placement simply above the mid-point of the lens, meant that I discovered it considerably extra awkward to function than mandatory. That stated, I think about for many photographers it gained’t be a management used often sufficient to matter.

Like all of Canon’s EF-M lenses, the 32mm F1.Four could be very compact. At barely Eight ounces in weight it will not weigh you down, both.

The EF-M 32mm F1.Four STM’s mount is made from metallic, and there’s no actual situation with mounting or un-mounting as such, though the truth that the barrel is similar diameter all through and that the majority of it’s made up by the rotating focus ring signifies that you need to seize it proper at its base when altering lenses.

As helpful as it’s to have such a large aperture, one situation I quickly bumped into with the EOS M50 was the shortage of an digital shutter that may allow shutter speeds past the the mechanical 1/4000sec restrict. This is applicable to different EOS M-series our bodies too, and presents an apparent problem when working open air in brighter circumstances. After all, an ND filter can assist right here, nevertheless it’s not a handy answer. (By the way, there’s a silent shutter possibility that employs an digital shutter hidden within the EOS M50’s scene modes, though you haven’t any company over publicity settings when that is enabled and you may’t in any other case entry the characteristic).


As with each different present optic within the EF-M collection, focusing is dealt with by an STM stepping motor. Right here, it’s a lead gear-type motor that guarantees clean and quiet focus for stills and ‘close to silence’ when capturing movies.

Canon’s personal literature makes it clear that the benefit of any such motor over the screw-type STM motor utilized in its different lenses pertains to compactness slightly than silence and velocity. After utilizing it for a while, I’m undecided whether or not the motor may be described as clean in its operation when capturing stills, however solely as a result of it’s clearly working at velocity to accumulate focus. I’d actually prioritize velocity over smoothness right here, so that is no criticism.

When capturing very shut topics, the EF-M 32mm F1.Four can take a second to realize focus, however for arms-length capturing and past, focus is quick and snappy.

In good gentle, the lens sometimes performs a fast shift to its approximate place earlier than a quick remaining shuffle for accuracy. Whereas that is audible, these sounds are simply masked by ambient noise, and so they’re not significantly obtrusive. When the lens hunts, it sometimes manages to journey between its full vary in round a second and a half, though this may clearly be improved when you’re not capturing up shut and are pleased to restrict the main target vary to the 0.5m-infinity vary.

Utilizing autofocus throughout video recording will lead to an audible low-frequency hum because it transitions between completely different focusing distances, slightly than the extra apparent, increased pitched whirring when focusing for stills. These sounds are picked up on recordings, however they’re additionally not distracting and are, once more, simply quashed by ambient noise. These actions are very clean, and I discovered the transitions seemed very pleasing in ensuing footage, assuming the digicam discovered focus with none points. There’s some noise from the lens because it’s manually centered throughout video recording, however when you flip the ring slowly sufficient you’ll not even discover this.

This picture exhibits the 32mm at its closest focusing distance, with the interior barrel prolonged from the principle physique of the lens.

Focus itself isn’t inside; the interior barrel extends by round half an inch or so when at its closest focus distance of 0.23m, though the outer barrel maintains the identical size always and the focusing ring additionally stays put. The focusing group isn’t mechanically linked to the ring, and response is speed-sensitive, not linear. Which means that the quantity of focus adjustment when manually focusing will fluctuate in line with how shortly you rotate the ring. You possibly can work by the entire focusing vary in as little as three quarters of a full rotation, however flip it too shortly and you could find yourself needing two-and-half rotations to maneuver between the 2 extremes. Video shooters manually focusing will miss the choice for linear focusing.

In any case, there’s ample room for effective management over handbook focus adjustment, and that is helped even additional by the peaking possibility discovered on each appropriate digicam, save for the unique EOS M. The lens additionally helps full-time handbook focus, which helps you to override the AF system by turning the focusing ring.

General, whereas the lens doesn’t function in full silence for stills nor video, it really works shortly sufficient for stills and easily sufficient for video.
