Panasonic GX8 versus Canon 5D Mark IV
The Panasonic Lumix DMC-GX8 and the Canon EOS 5D Mark IV are two digital cameras that were announced, respectively, in July 2015 and August 2016. The GX8 is a mirrorless interchangeable lens camera, while the 5D Mark IV is a DSLR. The cameras are based on a Four Thirds (GX8) and a full frame sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Canon provides 30.1 MP.
The side-by-side display below illustrates the physical size and weight of the Panasonic GX8 and the Canon 5D Mark IV. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions 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 GX8 – 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 Canon 5D Mark IV is considerably larger (69 percent) than the Panasonic GX8. Moreover, the 5D Mark IV is substantially heavier (83 percent) than the GX8. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 (GX8) and the Canon EF Lens Catalog (5D Mark IV). Mirrorless cameras, such as the Panasonic GX8, 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX8 was launched at a markedly lower price (by 66 percent) than the 5D Mark IV, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 Panasonic GX8 features a Four Thirds sensor and the Canon 5D Mark IV a full frame sensor. The sensor area in the 5D Mark IV is 284 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GX8 has a native 4:3 aspect ratio, while the one in the 5D Mark IV offers a 3:2 aspect.
With 30.1MP, the 5D Mark IV offers a higher resolution than the GX8 (20.2MP), but the 5D Mark IV nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 3.34μm for the GX8) due to its larger sensor. Moreover, the 5D Mark IV is a somewhat more recent model (by 1 year and 1 month) than the GX8, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 5D Mark IV offers substantially better image quality than the GX8 (overall score 16 points higher). The advantage is based on 1.3 bits higher color depth, 1 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. 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 (4K/30p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX8 has an electronic viewfinder (2360k dots), while the 5D Mark IV 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 following table reports on some other key feature differences and similarities of the Panasonic GX8, the Canon 5D Mark IV, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Reasons to prefer the Canon EOS 5D Mark IV:
- More detail: Has more megapixels (30.1 vs 20.2MP), which boosts linear resolution by 25%.
- Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.9 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.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- Longer lasting: Gets more shots (900 versus 330) out of a single battery charge.
- More modern: Was introduced somewhat (1 year and 1 month) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark IV emerges as the winner of the match-up (11 : 9 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.
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 GX8 and the 5D Mark IV 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. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
