Canon G1 X Mark II versus Panasonic GM5

The Canon PowerShot G1 X Mark II and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in February 2014 and September 2014. The G1X Mark II is a fixed lens compact, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X Mark II) and a Four Thirds sensor. The Canon has a resolution of 13 megapixel, whereas the Panasonic provides 15.8 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G1 X Mark II and the Panasonic GM5. Three consecutive perspectives from the front, the top, and the back are presented. 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 II – represents 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 Panasonic GM5 is notably smaller (31 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the GM5 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II has a lens build in, whereas the GM5 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 GM5 and their specifications in the Micro Four Thirds 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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 imaging sensor is a crucial determinant 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 is 14 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Canon G1 X Mark II and Panasonic GM5 sensor measures
Sensor size

Despite having a smaller sensor, the GM5 offers a higher resolution of 15.8 megapixel, compared with 13 MP of the G1X Mark II. 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 3.77μm versus 4.49μm for the G1X Mark II). However, it should be noted that the GM5 is a somewhat more recent model (by 7 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

G1X Mark II versus GM5 MP
Sensor resolution

For most 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 GM5 has a markedly higher DXO score than the G1X Mark II (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.9 EV in additional dynamic range, and 0.3 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GM5 provides a faster frame rate than the G1X Mark II. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GM5 has an electronic viewfinder (1166k 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. The table below summarizes some of the other core capabilities of the Canon G1 X Mark II and Panasonic GM5 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Reasons to prefer the Panasonic Lumix DMC-GM5:

  • More detail: Has more megapixels (15.8 vs 13MP), which boosts linear resolution by 10%.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (99x60mm vs 116x74mm) and will fit more readily into a bag.
  • More modern: Was introduced somewhat (7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GM5 emerges as the winner of the match-up (8 : 6 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.

G1X Mark II 06:08 GM5

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 II or the GM5 handle or 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. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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.
