Panasonic GX7 versus Canon M100

The Panasonic Lumix DMC-GX7 and the Canon EOS M100 are two digital cameras that were announced, respectively, in August 2013 and August 2017. Both the GX7 and the M100 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX7) and an APS-C (M100) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 24 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: Panasonic GX7 vs Canon M100

The side-by-side display below illustrates the physical size and weight of the Panasonic GX7 and the Canon M100. The two cameras are presented according to their relative size. 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 GX7 – 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 Canon M100 is notably smaller (17 percent) than the Panasonic GX7. Moreover, the M100 is markedly lighter (25 percent) than the GX7. In this context, it is worth noting that neither the GX7 nor the M100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GX7 gets 350 shots out of its DMW-BLG10 battery, while the M100 can take 295 images on a single charge of its LP-E12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 camera’s price is obviously a critical decision-making factor. 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 M100 was launched at a markedly lower price (by 50 percent) than the GX7, 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.

 

Sensor comparison: Panasonic GX7 vs Canon M100

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GX7 features a Four Thirds sensor and the Canon M100 an APS-C sensor. The sensor area in the M100 is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the GX7 has a native 4:3 aspect ratio, while the one in the M100 offers a 3:2 aspect.

Panasonic GX7 and Canon M100 sensor measures

With 24MP, the M100 offers a higher resolution than the GX7 (15.8MP), but the M100 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GX7). Yet, the M100 is a much more recent model (by 4 years) than the GX7, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

GX7 versus M100 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the M100 has a markedly higher DXO score than the GX7 (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.7 EV in additional dynamic range, and 0.8 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 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Panasonic GX7 vs Canon M100

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX7 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M100 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GX7 and Canon M100 along with similar information for a selection of comparators.

One feature that differentiates the GX7 and the M100 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the M100 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX7 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GX7 and the M100 write their imaging data to SDXC cards.

The M100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX7 was succeeded by the Panasonic GX85.

Review summary: Panasonic GX7 vs Canon M100

So how do things add up? Which of the two cameras – the Panasonic GX7 or the Canon M100 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX7:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Longer lasting: Can take more shots (350 versus 295) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been available for much longer (launched in August 2013).

ilogo

Advantages of the Canon EOS M100:

  • More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
  • 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 (0.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
  • Faster burst: Shoots at higher frequency (6.1 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (108x67mm vs 123x71mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 100g or 25 percent) and is thus easier to take along.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Reflects 4 years of technical progress since the GX7 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M100 emerges as the winner of the match-up (10 : 7 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.

GX7 07:10 M100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX7 or the M100. 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
