The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1X Mark II was launched at a markedly lower price (by 84 percent) than the Q2, which puts it into a different market segment. 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. 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 II features an 1.5-inch sensor and the Leica Q2 a full frame sensor. The sensor area in the Q2 is 230 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 1.0. The sensor in the G1X Mark II has a native 4:3 aspect ratio, while the one in the Q2 offers a 3:2 aspect.

With 46.7MP, the Q2 offers a higher resolution than the G1X Mark II (13MP), but the Q2 has smaller individual pixels (pixel pitch of 4.30μm versus 4.49μm for the G1X Mark II). Yet, the Q2 is a much more recent model (by 5 years) than the G1X Mark II, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 G1 X Mark II are 20.8 x 15.6 inches or 52.8 x 39.6 cm for good quality, 16.6 x 12.5 inches or 42.3 x 31.7 cm for very good quality, and 13.9 x 10.4 inches or 35.2 x 26.4 cm for excellent quality prints.

The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Leica Q2 are ISO 50 to ISO 50000 (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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under consideration, the Q2 offers substantially better image quality than the G1X Mark II (overall score 38 points higher). The advantage is based on 4.9 bits higher color depth, 2.7 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Q2 provides a better video resolution than the G1X Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Q2 has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark II, the Leica Q2, and comparable cameras.

Notes: *) 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 II has one, while the Q2 does not. While the built-in flash of the G1X Mark II is not very powerful, it can at times be useful as a fill-in light.

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 Q2 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 II 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 G1X Mark II is equipped with a zoom lens, while the Q2 comes with a built-in prime. The G1X Mark II has a 24-120mm f/2.0-3.9 optic and the Q2 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 Q2 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G1X Mark II and the Q2 write their files to SDXC cards. The Q2 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G1X Mark II 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 II and Leica Q2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The Q2 is a recent model that features in the current product line-up of Leica. In contrast, the G1X Mark II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G1X Mark II was succeeded by the Canon G1 X Mark III. Further information on the features and operation of the G1X Mark II and Q2 can be found, respectively, in the Canon G1 X Mark II Manual (free pdf) or the online Leica Q2 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G1 X Mark II and the Leica Q2? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot G1 X Mark II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (116x74mm vs 130x80mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 165g or 23 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 (84 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2014).

Reasons to prefer the Leica Q2:

• More detail: Has more megapixels (46.7 vs 13MP), which boosts linear resolution by 93%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (38 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4.9 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.7 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (20 vs 5.2 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/2.0).
• Longer lasting: Gets more shots (370 versus 240) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• 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 of technical progress since the G1X Mark II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Q2 is the clear winner of the contest (17 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

How about other alternatives? Do the specifications of the Canon G1 X Mark II and the Leica Q2 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G1X Mark II or the Q2 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
