Canon 100D vs Panasonic GM1
The Canon EOS 100D (called Canon SL1 in some regions) and the Panasonic Lumix DMC-GM1 are two digital cameras that were announced, respectively, in March 2013 and October 2013. The 100D is a DSLR, while the GM1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (100D) and a Four Thirds (GM1) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 100D vs Panasonic GM1
The physical size and weight of the Canon 100D and the Panasonic GM1 are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.
The 100D can be obtained in two different colors (black, white), while the GM1 is available in three color-versions (black, silver, red).
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 (49 percent) than the Canon 100D. Moreover, the GM1 is substantially lighter (50 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the GM1 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (100D) and the Micro Four Thirds Lens Catalog (GM1). Mirrorless cameras, such as the GM1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 100D was launched at a markedly lower price (by 27 percent) than the GM1, 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: Canon 100D vs Panasonic GM1
The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 100D has a native 3:2 aspect ratio, while the one in the GM1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 17.9MP, the 100D offers a higher resolution than the GM1 (15.8MP), but the 100D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the GM1) due to its larger sensor. However, the GM1 is a somewhat more recent model (by 6 months) than the 100D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600..
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GM1 provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Feature comparison: Canon 100D vs Panasonic GM1
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 100D 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 adjacent table lists some of the other core features of the Canon 100D and Panasonic GM1 along with similar information for a selection of comparators.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GM1 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
Concerning the storage of imaging data, both the 100D and the GM1 write their files to SDXC cards.
Connectivity comparison: Canon 100D vs Panasonic GM1
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 100D and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D has a hotshoe, while the GM1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 100D and the GM1 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the GM1 was followed by the Panasonic GM5.
Review summary: Canon 100D vs Panasonic GM1
So what is the bottom line? Is the Canon 100D better than the Panasonic GM1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 15.8MP) with a 8% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image framing and settings control.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
- Longer lasting: Can take more shots (380 versus 230) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in March 2013).
Arguments in favor of the Panasonic Lumix DMC-GM1:
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (99x55mm vs 117x91mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 203g or 50 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Was introduced somewhat (6 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the 100D emerges as the winner of the contest (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.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 100D and the GM1 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
