Panasonic GH4 versus Panasonic G6

The Panasonic Lumix DMC-GH4 and the Panasonic Lumix DMC-G6 are two digital cameras that were revealed to the public, respectively, in February 2014 and April 2013. Both the GH4 and the G6 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.9 megapixel. 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 G6

The side-by-side display below illustrates the physical size and weight of the Panasonic GH4 and the Panasonic G6. 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 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 G6 is notably smaller (16 percent) than the Panasonic GH4. Moreover, the G6 is markedly lighter (30 percent) than the GH4. It is worth mentioning in this context that the GH4 is splash and dust resistant, while the G6 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. 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.

Concerning battery life, the GH4 gets 500 shots out of its DMW-BLF19 battery, while the G6 can take 340 images on a single charge of its DMW-BLC12 power pack.

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 G6 was launched at a markedly lower price (by 60 percent) than the GH4, 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: Panasonic GH4 vs Panasonic G6

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. 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 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 G6 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixel. This similarity in sensor specs implies that both the GH4 and the G6 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GH4 is a somewhat more recent model (by 9 months) than the G6, and its sensor might have benefitted from technological advances during this time.

GH4 versus G6 MP

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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. Of the two cameras under review, the GH4 provides substantially higher image quality than the G6, with an overall score that is 13 points higher. This advantage is based on 1.9 bits higher color depth, 1.3 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GH4 provides a higher video resolution than the G6. It can shoot video footage at 4K/30p, while the G6 is limited to 1080/60p.

Feature comparison: Panasonic GH4 vs Panasonic G6

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH4 offers a substantially higher resolution than the one in the G6 (2359k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Panasonic GH4, the Panasonic G6, and comparable cameras.

Review summary: Panasonic GH4 vs Panasonic G6

So what conclusions can be drawn? Which of the two cameras – the Panasonic GH4 or the Panasonic G6 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Panasonic Lumix DMC-GH4:

  • Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1440k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 7 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (500 versus 340) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Is somewhat more recent (announced 9 months after the G6).

Arguments in favor of the Panasonic Lumix DMC-G6:

  • More compact: Is smaller (122x85mm vs 133x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 170g or 30 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in April 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the GH4 is the clear winner of the match-up (10 : 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 before making a decision on a new camera.

GH4 10:04 G6

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 GH4 or the G6. 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 why expert reviews are important.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
