Panasonic GH4 versus Panasonic GH5

The Panasonic Lumix DMC-GH4 and the Panasonic Lumix DC-GH5 are two enthusiast cameras that were revealed to the public, respectively, in February 2014 and January 2017. Both the GH4 and the GH5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH4 has a resolution of 15.9 megapixel, whereas the GH5 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: Panasonic GH4 vs Panasonic GH5

An illustration of the physical size and weight of the Panasonic GH4 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 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 GH4 – represents the basis or 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 (10 percent) than the Panasonic GH4. Moreover, the GH5 is markedly heavier (29 percent) than the GH4. 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 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 GH4 was launched at a somewhat lower price (by 25 percent) than the GH5, which makes it more attractive for photographers on a tight budget. 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 GH4 vs Panasonic GH5

The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and 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.

Panasonic GH4 and Panasonic GH5 sensor measures

While the two cameras under review share the same sensor size, the GH5 offers a higher resolution of 20.2 megapixel, compared with 15.9 MP of the GH4. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the GH5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.76μm for the GH4). However, it should be noted that the GH5 is much more recent (by 2 years and 10 months) than the GH4, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the GH5 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

GH4 versus GH5 MP

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 GH4. It can shoot movie footage at 4K/60p, while the GH4 is limited to 4K/30p.

 

Feature comparison: Panasonic GH4 vs Panasonic GH5

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 GH4 (3680k vs 2359k dots). The adjacent table lists some of the other core features of the Panasonic GH4 and Panasonic GH5 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The GH5 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GH4 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GH4 was succeeded by the Panasonic GH5.

Review summary: Panasonic GH4 vs Panasonic GH5

So what is the bottom line? Which of the two cameras – the Panasonic GH4 or the Panasonic GH5 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC-GH4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Less heavy: Is lighter (by 165g or 23 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (500 versus 410) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in February 2014).


Advantages of the Panasonic Lumix DC-GH5:

  • More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2359k 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 1036k dots).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Reflects 2 years and 10 months of technical progress since the GH4 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GH5 emerges as the winner of the match-up (8 : 6 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.

GH4 06:08 GH5

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH4 and the GH5 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
