Canon G1 X versus Panasonic GM1
The Canon PowerShot G1 X and the Panasonic Lumix DMC-GM1 are two digital cameras that were officially introduced, respectively, in January 2012 and October 2013. The G1X is a fixed lens compact, while the GM1 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X) and a Four Thirds (GM1) sensor. The Canon has a resolution of 14.2 megapixel, whereas the Panasonic provides 15.8 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 vs Panasonic GM1
The side-by-side display below illustrates the physical size and weight of the Canon G1 X and the Panasonic GM1. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – 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 Panasonic GM1 is considerably smaller (43 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the GM1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens build in, whereas the GM1 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 GM1 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 camera comparisons there.

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. 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: Canon G1 X vs Panasonic GM1
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 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.
Despite having a smaller sensor, the GM1 offers a higher resolution of 15.8 megapixel, compared with 14.2 MP of the G1X. 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 4.30μm for the G1X). However, it should be noted that the GM1 is a somewhat more recent model (by 1 year and 9 months) than the G1X, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 GM1 has a markedly higher DXO score than the G1X (overall score 6 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GM1 provides a faster frame rate than the G1X. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/24p.
Feature comparison: Canon G1 X vs Panasonic GM1
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GM1 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 and Panasonic GM1 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

- Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
- More detailed LCD: Has a higher resolution rear screen (1036k vs 922k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (5 vs 1.9 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (99x55mm vs 117x81mm) and will fit more readily into a bag.
- More modern: Was introduced somewhat (1 year and 9 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the GM1 is the clear winner of the contest (10 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.
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 or the GM1 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
