Canon 100D versus Panasonic GX85
The Canon EOS 100D (called Canon SL1 in some regions) and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were officially introduced, respectively, in March 2013 and April 2016. The 100D is a DSLR, while the GX85 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (100D) and a Four Thirds (GX85) sensor. The Canon has a resolution of 17.9 megapixel, whereas the Panasonic provides 15.8 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 100D vs Panasonic GX85
The physical size and weight of the Canon 100D and the Panasonic GX85 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. 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 – the 100D – represents 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 Panasonic GX85 is notably smaller (19 percent) than the Canon 100D. However, the GX85 is markedly heavier (5 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the GX85 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (100D) and the Micro Four Thirds Lens Catalog (GX85). Mirrorless cameras, such as the GX85, 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 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 100D was launched at a markedly lower price (by 31 percent) than the GX85, 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 100D vs Panasonic GX85
The size of the imaging sensor is a crucial determinant 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. 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 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 GX85 a Four Thirds sensor. The sensor area in the GX85 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 GX85 offers a 4:3 aspect.
With 17.9MP, the 100D offers a higher resolution than the GX85 (15.8MP), but the 100D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the GX85) due to its larger sensor. However, the GX85 is a somewhat more recent model (by 3 years) than the 100D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 GX85 has a markedly higher DXO score than the 100D (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 1.3 EV in additional dynamic range, 0.3 stops of reduced 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX85 provides a better video resolution than the 100D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Feature comparison: Canon 100D vs Panasonic GX85
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX85 has an electronic viewfinder (2765k dots), while the 100D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon 100D and Panasonic GX85 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

If the number of relative strengths (bullet points above) is taken as a guide, the GX85 is the clear winner of the contest (12 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.
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 100D or the GX85 handle or perform in practice. 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 where reviews by experts come in. 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).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
