Panasonic GM5 versus Canon M100

The Panasonic Lumix DMC-GM5 and the Canon EOS M100 are two digital cameras that were revealed to the public, respectively, in September 2014 and August 2017. Both the GM5 and the M100 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GM5) 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 GM5 vs Canon M100

An illustration of the physical size and weight of the Panasonic GM5 and the Canon M100 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 side – the GM5 – 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 Canon M100 is notably larger (22 percent) than the Panasonic GM5. Moreover, the M100 is substantially heavier (43 percent) than the GM5. In this context, it is worth noting that neither the GM5 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 GM5 gets 220 shots out of its DMW-BLH7 battery, while the M100 can take 295 images on a single charge of its LP-E12 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 camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The M100 was launched at a markedly lower price (by 33 percent) than the GM5, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 GM5 vs Canon M100

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GM5 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 GM5 has a native 4:3 aspect ratio, while the one in the M100 offers a 3:2 aspect.

Panasonic GM5 and Canon M100 sensor measures

With 24MP, the M100 offers a higher resolution than the GM5 (15.8MP), but the M100 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GM5). Yet, the M100 is a much more recent model (by 2 years and 11 months) than the GM5, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

GM5 versus M100 MP

For many 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 M100 offers substantially better image quality than the GM5 (overall score 12 points higher). The advantage is based on 1.4 bits higher color depth, 1.2 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 GM5 vs Canon M100

Beyond body and sensor, cameras can and do differ across a range 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 M100 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GM5 and Canon M100 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The M100 has one, while the GM5 does not. While the build-in flash of the M100 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GM5 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 GM5 and the M100 write their imaging data to SDXC cards.

Review summary: Panasonic GM5 vs Canon M100

So how do things add up? Which of the two cameras – the Panasonic GM5 or the Canon M100 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Panasonic Lumix DMC-GM5:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (99x60mm vs 108x67mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 91g or 30 percent) and hence easier to carry around.
  • 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 September 2014).

ilogo

Arguments in favor of the Canon EOS M100:

  • More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
  • Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).

  • Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Longer lasting: Gets more shots (295 versus 220) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More modern: Reflects 2 years and 11 months of technical progress since the GM5 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M100 is the clear winner of the contest (14 : 6 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.

GM5 06:14 M100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GM5 and the M100 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
