Canon G1 X Mark III versus Leica M Typ 240

The Canon PowerShot G1 X Mark III and the Leica M (Typ 240) are two enthusiast cameras that were revealed to the public, respectively, in October 2017 and September 2012. The G1X Mark III is a fixed lens compact, while the M Typ 240 is a rangefinder-style mirrorless. The cameras are based on an APS-C (G1X Mark III) and a full frame (M Typ 240) sensor. The Canon has a resolution of 24 megapixel, whereas the Leica provides 23.7 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon G1 X Mark III vs Leica M Typ 240

The physical size and weight of the Canon G1 X Mark III 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 size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the G1X Mark III – represents the basis or 100 percent across all the size and weight measures).

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 notably larger (24 percent) than the Canon G1 X 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.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build 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 find an overview of optics for the M Typ 240 and their specifications in the Leica M Lens Catalog.

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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G1X Mark III was launched at a lower price than the M Typ 240, despite having a lens build in. 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: Canon G1 X Mark III vs Leica M Typ 240

The size of the imaging sensor is a crucial determinant 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 III features an APS-C sensor and the Leica M Typ 240 a full frame sensor. The sensor area in the M Typ 240 is 158 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 M Typ 240 sensor measures

Despite having a smaller sensor, the Canon G1 X Mark III offers a higher resolution of 24 megapixel, compared with 23.7 MP of the Leica M Typ 240. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 6.01μm for the M Typ 240). However, it should be noted that the G1X Mark III is much more recent (by 5 years) than the M Typ 240, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The G1X Mark III has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G1X Mark III 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: Canon G1 X Mark III vs Leica M Typ 240

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the M Typ 240 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon G1 X Mark III and Leica M Typ 240 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark III has one, while the M Typ 240 does not. While the build-in flash of the G1X Mark III is not very powerful, it can at times be useful as a fill-in light.

Both the G1X Mark III and the M Typ 240 write their imaging data to SDXC cards.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G1X Mark III or the M Typ 240 handle or 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. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
