Compare G1X Mark III versus Q3 top
Comparison G1X Mark III or Q3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica Q3 is notably larger (16 percent) than the Canon G1 X Mark III. Moreover, the Q3 is substantially heavier (86 percent) than the G1X Mark III. 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.

Concerning battery life, the G1X Mark III gets 200 shots out of its Canon NB-13L battery, while the Q3 can take 350 images on a single charge of its Leica BP-SCL6 power pack. The power pack in the Q3 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. 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 G1X Mark III was launched at a markedly lower price (by 78 percent) than the Q3, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Leica Q3 a full frame sensor. The sensor area in the Q3 is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G1 X Mark III and Leica Q3 sensor measures

With 60.3MP, the Q3 offers a higher resolution than the G1X Mark III (24MP), but the Q3 nevertheless has marginally larger individual pixels (pixel pitch of 3.79μm versus 3.72μm for the G1X Mark III) due to its larger sensor. Moreover, the Q3 is a much more recent model (by 5 years and 7 months) than the G1X Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Q3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica Q3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Q3 for good quality output (200 dots per inch) amounts to 47.6 x 31.6 inches or 121 x 80.4 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.8 x 64.3 cm, and for excellent quality (300 dpi) 31.8 x 21.1 inches or 80.7 x 53.6 cm. The corresponding values for the Canon G1 X Mark III 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 Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Leica Q3 are ISO 50 to ISO 100000 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

G1X Mark III versus Q3 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Q3 provides a better video resolution than the G1X Mark III. It can shoot movie footage at 8K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the Q3 offers a substantially higher resolution than the one in the G1X Mark III (5760k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Canon G1 X Mark III, the Leica Q3, and comparable cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark III has one, while the Q3 does not. While the built-in flash of the G1X Mark III is not very powerful, it can at times be useful as a fill-in light.

The G1X Mark III 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 Q3 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, the Q3 is one of those camera that have an additional 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 G1 X Mark III and the Leica Q3 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 G1X Mark III is equipped with a zoom lens, while the Q3 comes with a built-in prime. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the Q3 offers a 28mm f/1.7 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Leica. The Q3 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G1X Mark III and the Q3 write their files to SDXC cards. The Q3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G1X Mark III can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G1 X Mark III and Leica Q3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The Q3 is a recent model that features in the current product line-up of Leica. In contrast, the G1X Mark III has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the G1X Mark III from Canon. Further information on the features and operation of the G1X Mark III and Q3 can be found, respectively, in the Canon G1 X Mark III Manual (free pdf) or the online Leica Q3 Manual.

Review summary

So how do things add up? Is the Canon G1 X Mark III better than the Leica Q3 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon PowerShot G1 X Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (115x78mm vs 130x80mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 344g or 46 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (78 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in October 2017).

ilogo

Arguments in favor of the Leica Q3:

  • More detail: Has more megapixels (60.3 vs 24MP), which boosts linear resolution by 59%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better video: Provides higher definition movie capture (8K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
  • More detailed LCD: Has a higher resolution rear screen (1840k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (15 vs 9 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/2.8).
  • Longer lasting: Gets more shots (350 versus 200) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More modern: Reflects 5 years and 7 months of technical progress since the G1X Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the Q3 is the clear winner of the contest (18 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

G1X Mark III 10:18 Q3

How about other alternatives? Do the specifications of the Canon G1 X Mark III and the Leica Q3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 G1X Mark III or the Q3. 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 hands-on reviews by experts 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
