Body comparison

An illustration of the physical size and weight of the Canon R3 and the Leica Q2 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon R3 vs Leica Q2
Compare R3 versus Q2 top
Comparison R3 or Q2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica Q2 is considerably smaller (52 percent) than the Canon R3. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Q2 has a lens built in, whereas the R3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the R3 gets 760 shots out of its Canon LP-E19 battery, while the Q2 can take 370 images on a single charge of its Leica BP-SCL4 power pack. As can be seen in the images above, the R3 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the R3 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The Q2 was launched at a lower price than the R3, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon R3 and Leica Q2 sensor measures

While the two cameras under review share the same sensor size, the Q2 offers a higher resolution of 46.7 megapixels, compared with 24 MP of the R3. This megapixels advantage translates into a 39 percent gain in linear resolution. On the other hand, these sensor specs imply that the Q2 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.30μm versus 6.00μm for the R3). Moreover, it should be noted, that the R3 is much more recent (by 2 years and 6 months) than the Q2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the Q2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica Q2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Q2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Canon R3 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The R3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS R3 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Leica Q2 are ISO 50 to ISO 50000 (no boost).

In terms of underlying technology, the R3 is build around a Stacked BSI-CMOS sensor, while the Q2 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

R3 versus Q2 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the R3, but is missing on the Q2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The R3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the Q2 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon R3 and the Leica Q2 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The R3 writes its imaging data to CFexpress (type B) or SDXC cards, while the Q2 uses SDXC cards. The R3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Q2 only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

It is notable that the R3 has a microphone port, which is missing on the Q2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Canon R3 (unlike the Q2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R3 and the Q2 are recent models that are part of the current product line-up. The Q2 replaced the earlier Leica Q Typ 116, while the R3 does not have a direct predecessor. Further information on the features and operation of the R3 and Q2 can be found, respectively, in the Canon R3 Manual (free pdf) or the online Leica Q2 Manual.

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
  • Better video: Provides higher definition movie capture (6K/60p vs 4K/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3680k dots).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (4150k vs 1040k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (760 versus 370) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 2 years and 6 months of technical progress since the Q2 launch.

ilogo

Advantages of the Leica Q2:

  • More detail: Has more megapixels (46.7 vs 24MP), which boosts linear resolution by 40%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
  • Ready to shoot: Has an integrated lens, whereas the R3 necessitates an extra lens.
  • More compact: Is smaller (130x80mm vs 150x143mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the R3).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in March 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the R3 is the clear winner of the match-up (22 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

R3 22:09 Q2

How about other alternatives? Do the specifications of the Canon R3 and the Leica Q2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R3 or the Q2. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
