Sony A7R II versus Panasonic GH5
The Sony Alpha A7R II and the Panasonic Lumix DC-GH5 are two enthusiast cameras that were officially introduced, respectively, in June 2015 and January 2017. Both the A7R II and the GH5 are mirrorless interchangeable lens cameras that are based on a full frame (A7R II) and a Four Thirds (GH5) sensor. The Sony has a resolution of 42.2 megapixel, whereas the Panasonic provides 20.2 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: Sony A7R II vs Panasonic GH5
The physical size and weight of the Sony A7R II and the Panasonic GH5 are illustrated 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 measures 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 A7R II – 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 Panasonic GH5 is notably larger (12 percent) than the Sony A7R II. Moreover, the GH5 is markedly heavier (16 percent) than the A7R II. 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 Sony FE Lens Catalog (A7R II) and the Micro Four Thirds Lens Catalog (GH5). 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 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 GH5 was launched at a markedly lower price (by 38 percent) than the A7R II, 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: Sony A7R II vs Panasonic GH5
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Sony A7R II features a full frame sensor and the Panasonic GH5 a Four Thirds sensor. The sensor area in the GH5 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the A7R II has a native 3:2 aspect ratio, while the one in the GH5 offers a 4:3 aspect.
With 42.2MP, the A7R II offers a higher resolution than the GH5 (20.2MP), but the A7R II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 3.34μm for the GH5) due to its larger sensor. However, the GH5 is a somewhat more recent model (by 1 year and 6 months) than the A7R II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the A7R II provides substantially higher image quality than the GH5, with an overall score that is 21 points higher. This advantage is based on 2.1 bits higher color depth, 0.9 EV in additional dynamic range, and 2.1 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 also of capturing video footage. 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 A7R II. It can shoot movie footage at 4K/60p, while the Sony is limited to 4K/30p.
Feature comparison: Sony A7R II vs Panasonic GH5
Beyond 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 A7R II (3680k vs 2400k dots).

The GH5 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7R II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7R II was succeeded by the Sony Alpha A7R III.
Review summary: Sony A7R II vs Panasonic GH5
So how do things add up? Which of the two cameras – the Sony A7R II or the Panasonic GH5 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Sony Alpha A7R II:
- More detail: Offers more megapixels (42.2 vs 20.2MP) with a 48% higher linear resolution.
- Better image quality: Scores substantially higher (21 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.1 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
- More compact: Is smaller (127x96mm vs 139x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 100g or 14 percent) and hence easier to carry around.
- More heavily discounted: Has been on the market for longer (launched in June 2015).
Arguments in favor of the Panasonic Lumix DC-GH5:
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2400k 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 1229k dots).
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (410 versus 290) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 6 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 (10 : 8 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 before making a decision on a new camera.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A7R II or the GH5 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.

Care should be taken when interpreting the review scores above, 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 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.
