Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X and the Leica M (Typ 240)? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Canon G7 X and the Leica M Typ 240 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The M Typ 240 can be obtained in two different colors (black, silver), while the G7X is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M Typ 240 is considerably larger (80 percent) than the Canon G7 X. It is noteworthy in this context that the M Typ 240 is splash and dust-proof, while the G7X does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens built in, whereas the M Typ 240 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the M Typ 240 and their specifications in the Leica M Lens Catalog.

Concerning battery life, the G7X gets 210 shots out of its Canon NB-13L battery, while the M Typ 240 can take 500 images on a single charge of its Leica BP-SCL2 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 G7X was launched at a lower price than the M Typ 240, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 G7 X features an one-inch sensor and the Leica M Typ 240 a full frame sensor. The sensor area in the M Typ 240 is 638 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 23.7MP, the M Typ 240 offers a higher resolution than the G7X (20MP), but the M Typ 240 nevertheless has larger individual pixels (pixel pitch of 6.01μm versus 2.41μm for the G7X) due to its larger sensor. However, the G7X is a somewhat more recent model (by 1 year and 11 months) than the M Typ 240, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Leica M Typ 240 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M Typ 240 for good quality output (200 dots per inch) amounts to 29.8 x 19.9 inches or 75.6 x 50.5 cm, for very good quality (250 dpi) 23.8 x 15.9 inches or 60.5 x 40.4 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.7 cm. The corresponding values for the Canon G7 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Leica M (Typ 240) are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the G7X is build around a BSI-CMOS sensor, while the M Typ 240 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the M Typ 240 offers substantially better image quality than the G7X (overall score 13 points higher). The advantage is based on 1 bits higher color depth, 0.6 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. 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 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 G7X provides a higher frame rate than the M Typ 240. It can shoot video footage at 1080/60p, while the Leica is limited to 1080/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the M Typ 240 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G7 X and Leica M Typ 240 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G7X has one, while the M Typ 240 does not. While the built-in flash of the G7X is not very powerful, it can at times be useful as a fill-in light.

The Canon G7 X has 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.

Concerning the storage of imaging data, both the G7X and the M Typ 240 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 G7 X and Leica M (Typ 240) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X offers wifi support, while the M Typ 240 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G7X and the M Typ 240 have been discontinued, but can regularly be found used on ebay. The M Typ 240 was replaced by the Leica M Typ 262, while the G7X was followed by the Canon G7 X Mark II. Further information on the features and operation of the G7X and M Typ 240 can be found, respectively, in the Canon G7 X Manual (free pdf) or the online Leica M Typ 240 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G7 X or the Leica M Typ 240 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot G7 X:

• Better video: Provides higher movie framerates (1080/60p versus 1080/25p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has a lens built-in, whereas the M Typ 240 requires a separate lens.
• More compact: Is smaller (103x60mm vs 139x80mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the M Typ 240).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Is somewhat more recent (announced 1 year and 11 months after the M Typ 240).

Advantages of the Leica M (Typ 240):

• More detail: Has more megapixels (23.7 vs 20MP), which boosts linear resolution by 9%.
• Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.7 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with different optics.
• Longer lasting: Gets more shots (500 versus 210) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been on the market for longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the G7X is the clear winner of the match-up (16 : 12 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X or the M Typ 240. 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
