Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G16 and the Leica M9? 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 side-by-side display below illustrates the physical size and weight of the Canon G16 and the Leica M9. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The M9 can be obtained in two different colors (black, silver), while the G16 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 M9 is notably larger (34 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the M9 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 has a lens built in, whereas the M9 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 M9 and their specifications in the Leica M Lens Catalog.

Concerning battery life, the G16 gets 360 shots out of its Canon NB-10L battery, while the M9 can take 550 images on a single charge of its Leica BLI-312 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 G16 was launched at a lower price than the M9, 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G16 features a 1/1.7-inch sensor and the Leica M9 a full frame sensor. The sensor area in the M9 is 1957 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.0. The sensor in the G16 has a native 4:3 aspect ratio, while the one in the M9 offers a 3:2 aspect.

With 18.1MP, the M9 offers a higher resolution than the G16 (12MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 3 years and 11 months) than the M9, 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 M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inches or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inches or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.1 x 29.4 cm. The corresponding values for the Canon G16 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Leica M9 are ISO 80 to ISO 2500 (no boost).

In terms of underlying technology, the G16 is build around a BSI-CMOS sensor, while the M9 uses a CCD 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.

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"). Of the two cameras under consideration, the M9 offers substantially better image quality than the G16 (overall score 15 points higher). The advantage is based on 1.5 bits higher color depth, and 1.9 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 are not only capable of taking still images, but can also record movies. The G16 indeed provides movie recording capabilities, while the M9 does not. The highest resolution format that the G16 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G16 and the M9 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The table below summarizes some of the other core capabilities of the Canon G16 and Leica M9 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 G16 has one, while the M9 does not. While the built-in flash of the G16 is not very powerful, it can at times be useful as a fill-in light.

The Canon G16 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 G16 and the M9 write their files to SDXC cards. The G16 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M9 cannot take advantage of Ultra High Speed SD cards.

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 G16 and Leica M9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 offers wifi support, while the M9 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G16 and the M9 have been discontinued, but can regularly be found used on ebay. The M9 was replaced by the Leica M Typ 240, while the G16 does not have a direct successor. Further information on the features and operation of the G16 and M9 can be found, respectively, in the Canon G16 Manual (free pdf) or the online Leica M9 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G16 or the Leica M9 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot G16:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has a lens built-in, whereas the M9 requires a separate lens.
• More compact: Is smaller (109x76mm 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 M9).
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 3 years and 11 months of technical progress since the M9 launch.

Reasons to prefer the Leica M9:

• More detail: Has more megapixels (18.1 vs 12MP), which boosts linear resolution by 25%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
• Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
• More flexible: Takes interchangeable lenses and can thus be used with different optics.
• Longer lasting: Gets more shots (550 versus 360) out of a single battery charge.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the G16 is the clear winner of the match-up (14 : 9 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 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G16 or the M9 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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 ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
