Panasonic GX8 versus Panasonic GH5
The Panasonic Lumix DMC-GX8 and the Panasonic Lumix DMC-GH5 are two digital cameras that were revealed to the public, respectively, in July 2015 and January 2017. Both the GX8 and the GH5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 20.2 megapixel.
An illustration of the physical size and weight of the Panasonic GX8 and the Panasonic GH5 is provided in the side-by-side display below. 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. 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 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 Panasonic GH5 is notably larger (31 percent) than the Panasonic GX8. Moreover, the GH5 is substantially heavier (49 percent) than the GX8. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera 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 40 percent) than the GH5, 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixel. This similarity in sensor specs implies that both the GX8 and the GH5 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GH5 is a somewhat more recent model (by 1 year and 5 months) than the GX8, and its sensor might have benefitted from technological advances during this time.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GH5 provides a faster frame rate than the GX8. It can shoot movie footage at 4K/60p, while the GX8 is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GH5 offers a substantially higher resolution than the one in the GX8 (3680k vs 2360k dots). The table below summarizes some of the other core capabilities of the Panasonic GX8 and Panasonic GH5 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the GX8 and the GH5 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX8 replaced the earlier Panasonic GX7, while the GH5 followed on from the Panasonic GH4.
So what is the bottom line? Is the Panasonic GX8 better than the Panasonic GH5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DMC-GX8:
- More compact: Is smaller (133x78mm vs 139x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 238g or 33 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in July 2015).
Reasons to prefer the Panasonic Lumix DMC-GH5:
- Better video: Provides higher movie framerates (4K/30p vs 4K/60p).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (3680k vs 2360k dots).
- 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 (410 versus 330) out of a single battery charge.
- More modern: Was introduced somewhat (1 year and 5 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the GH5 emerges as the winner of the match-up (6 : 4 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 specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX8 or the GH5. 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 why expert reviews are important. The table below summarizes the assessments of some of the best known 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
