Canon G1 X Mark III versus Panasonic LX15

The Canon PowerShot G1 X Mark III and the Panasonic Lumix DMC-LX15 (labelled Panasonic LX10 in some countries) are two digital cameras that were announced, respectively, in October 2017 and September 2016. Both the G1X Mark III and the LX15 are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and an one-inch (LX15) sensor. The Canon has a resolution of 24 megapixel, whereas the Panasonic provides 20 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 Panasonic LX15

The physical size and weight of the Canon G1 X Mark III and the Panasonic LX15 are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

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. The LX15 was launched at a markedly lower price (by 46 percent) than the G1X Mark III, which puts it into a different market segment. 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 Mark III vs Panasonic LX15

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Panasonic LX15 an one-inch sensor. The sensor area in the LX15 is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G1 X Mark III and Panasonic LX15 sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the LX15 (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the LX15) due to its larger sensor. Moreover, the G1X Mark III is a somewhat more recent model (by 1 year) than the LX15, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LX15 provides a better video resolution than the G1X Mark III. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Canon G1 X Mark III vs Panasonic LX15

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), which can be very helpful when shooting in bright sunlight. In contrast, the LX15 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 III and Panasonic LX15 in connection with corresponding information for a sample of similar cameras.

G1X Mark III 06:08 LX15

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 LX15 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 why hands-on reviews by experts are important.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
