Canon G1 X Mark III versus Panasonic LX100

The Canon PowerShot G1 X Mark III and the Panasonic Lumix DMC-LX100 are two enthusiast cameras that were officially introduced, respectively, in October 2017 and September 2014. Both the G1X Mark III and the LX100 are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and a Four Thirds (LX100) sensor. The Canon has a resolution of 24 megapixel, whereas the Panasonic provides 12.7 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 Panasonic LX100

The physical size and weight of the Canon G1 X Mark III and the Panasonic LX100 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth 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 side – the G1X Mark III – represents the basis for the calculations 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 LX100 is notably smaller (15 percent) than the Canon G1 X Mark III. Moreover, the LX100 is slightly lighter (2 percent) than the G1X Mark III. It is worth mentioning in this context that the G1X Mark III is splash and dust resistant, while the LX100 does not feature any corresponding weather-sealing.

Concerning battery life, the G1X Mark III gets 200 shots out of its NB-13L battery, while the LX100 can take 300 images on a single charge of its DMW-BLG10 power pack.

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. The LX100 was launched at a markedly lower price (by 31 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 LX100

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 LX100 a Four Thirds sensor. The sensor area in the LX100 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the G1X Mark III has a native 3:2 aspect ratio, while the one in the LX100 offers a 4:3 aspect.

Canon G1 X Mark III and Panasonic LX100 sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the LX100 (12.7MP), but the G1X Mark III has smaller individual pixels (pixel pitch of 3.72μm versus 4.21μm for the LX100). However, the G1X Mark III is a somewhat more recent model (by 3 years and 1 month) than the LX100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the LX100 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 LX100

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the LX100 offers a higher resolution than the one in the G1X Mark III (2764k vs 2360k dots). The adjacent table lists some of the other core features of the Canon G1 X Mark III and Panasonic LX100 along with similar information for a selection of comparators.

Both the G1X Mark III and the LX100 have zoom lenses build in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the LX100 offers a 24-75mm f/1.7-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Panasonic provide the same view at the wide-angle end, but the Panasonic has more tele-photo reach at the long end. The LX100 offers the faster maximum aperture.

Both the G1X Mark III and the LX100 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G1X Mark III replaced the earlier Canon G1 X Mark II, while the LX100 does not have a direct predecessor.

Review summary: Canon G1 X Mark III vs Panasonic LX100

So what is the bottom line? Which of the two cameras – the Canon G1 X Mark III or the Panasonic LX100 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

logo checkmark

Advantages of the Panasonic Lumix DMC-LX100:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 2360k dots).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 9 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/2.8).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (115x66mm vs 115x78mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (300 versus 200) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the LX100 emerges as the winner of the match-up (10 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

G1X Mark III 08:10 LX100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G1X Mark III and the LX100 in practical situations. 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 expert reviews are important. The table below summarizes the assessments of some of the best known 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.
