Canon 70D versus Panasonic GX80
The Canon EOS 70D and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were announced, respectively, in July 2013 and April 2016. The 70D is a DSLR, while the GX80 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (70D) and a Four Thirds sensor. The Canon has a resolution of 20 megapixel, whereas the Panasonic provides 15.8 MP.
The physical size and weight of the Canon 70D and the Panasonic GX80 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 70D – 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 GX80 is considerably smaller (40 percent) than the Canon 70D. Moreover, the GX80 is substantially lighter (44 percent) than the 70D. It is worth mentioning in this context that the 70D is splash and dust resistant, 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 Canon EF Lens Catalog (70D) and the Micro Four Thirds Lens Catalog (GX80). Mirrorless cameras, such as the GX80, 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 comparisons there.

The listed 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.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 70D features an APS-C sensor and the Panasonic GX80 a Four Thirds sensor. The sensor area in the GX80 is 33 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 70D has a native 3:2 aspect ratio, while the one in the GX80 offers a 4:3 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 somewhat more recent model (by 2 years and 9 months) than the 70D, 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 GX80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX80 provides a better video resolution than the 70D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety 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 Canon 70D and Panasonic GX80 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

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.
So what conclusions can be drawn? Is there a clear favorite between the Canon 70D and the Canon 70D? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 70D:
- More detail: Offers more megapixels (20 vs 15.8MP) with a 15% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has an LCD display on top to control 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: Can take more shots (920 versus 290) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been available for much longer (launched in July 2013).
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 broader range 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 will fit more readily into a bag.
- Less heavy: Has a lower weight (by 329g or 44 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
- 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.
If the count of individual advantages (bullet points above) is taken as a guide, the GX80 comes out slightly ahead of the 70D (11 : 10 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 70D and the GX80 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
