Panasonic GX80 versus Canon 70D
The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Canon EOS 70D are two digital cameras that were revealed to the public, respectively, in April 2016 and July 2013. The GX80 is a mirrorless interchangeable lens camera, while the 70D is a DSLR. The cameras are based on a Four Thirds (GX80) and an APS-C (70D) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 20 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 GX80 vs Canon 70D
The physical size and weight of the Panasonic GX80 and the Canon 70D are illustrated in the side-by-side display below. 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 GX80 – 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 70D is considerably larger (67 percent) than the Panasonic GX80. Moreover, the 70D is substantially heavier (77 percent) than the GX80. It is noteworthy in this context that the 70D is splash and dust-proof, while the GX80 does not feature any corresponding weather-sealing.
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 Micro Four Thirds Lens Catalog (GX80) and the Canon EF Lens Catalog (70D). Mirrorless cameras, such as the Panasonic GX80, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
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 GX80 was launched at a markedly lower price (by 33 percent) than the 70D, 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: Panasonic GX80 vs Canon 70D
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 GX80 features a Four Thirds sensor and the Canon 70D an APS-C sensor. The sensor area in the 70D is 50 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 GX80 has a native 4:3 aspect ratio, while the one in the 70D offers a 3:2 aspect.
With 20MP, the 70D offers a higher resolution than the GX80 (15.8MP), but the 70D nevertheless has larger individual pixels (pixel pitch of 4.11μm versus 3.77μm for the GX80) due to its larger sensor. However, the GX80 is a much more recent model (by 2 years and 9 months) than the 70D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GX80 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 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 image quality. 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, but the GX80 provides a higher video resolution than the 70D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/30p.
Feature comparison: Panasonic GX80 vs Canon 70D
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX80 has an electronic viewfinder (2765k dots), while the 70D 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 adjacent table lists some of the other core features of the Panasonic GX80 and Canon 70D along with similar information for a selection of comparators.

The GX80 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 70D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 70D was succeeded by the Canon 80D.
Review summary: Panasonic GX80 vs Canon 70D
So how do things add up? Which of the two cameras – the Panasonic GX80 or the Canon 70D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Panasonic Lumix DMC-GX80:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- More framing info: Has an electronic viewfinder that displays shooting data.
- Faster burst: Shoots at higher frequency (8 vs 7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (122x71mm vs 139x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 329g or 44 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More modern: Reflects 2 years and 9 months of technical progress since the 70D launch.
Arguments in favor of the Canon EOS 70D:
- More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has a control panel on top to check shooting parameters.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Longer lasting: Gets more shots (920 versus 290) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More heavily discounted: Has been around for much longer (launched in July 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the GX80 comes out slightly ahead of the 70D (11 : 10 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.
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 GX80 and the 70D 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.
