Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX7 and the Panasonic Lumix DMC-G6? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Panasonic GX7 and the Panasonic G6 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The GX7 can be obtained in two different colors (black, silver), while the G6 is available in three color-versions (black, silver, white).

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 larger (19 percent) than the Panasonic GX7. However, the G6 is slightly lighter (3 percent) than the GX7. In this context, it is worth noting that neither the GX7 nor the G6 are weather-sealed.

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 compare the optics available 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 GX7 gets 350 shots out of its Panasonic DMW-BLG10 battery, while the G6 can take 340 images on a single charge of its Panasonic DMW-BLC12 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 40 percent) than the GX7, 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

While the two cameras under review share the same sensor size, the G6 offers a slightly higher resolution of 15.9 megapixels, compared with 15.8 MP of the GX7. This megapixels advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the G6 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.77μm for the GX7). Moreover, it should be noted, that the GX7 is a somewhat more recent model (by 3 months) than the G6, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

The Panasonic Lumix DMC-GX7 has a native sensitivity range from ISO 125 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DMC-G6 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 160-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many 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 GX7 has a notably higher overall DXO score than the G6 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.3 bits higher color depth, 0.7 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GX7 offers a substantially higher resolution than the one in the G6 (2760k vs 1440k dots). The table below summarizes some of the other core capabilities of the Panasonic GX7 and Panasonic G6 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the GX7 and the G6 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the G6 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GX7 and the Panasonic G6 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the GX7 and the G6 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-GX7 and Panasonic Lumix DMC-G6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G6 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The GX7 does not feature such a mic input.

Both the GX7 and the G6 have been discontinued, but can regularly be found used on ebay. The G6 was replaced by the Panasonic G7, while the GX7 was followed by the Panasonic GX85. Further information on the features and operation of the GX7 and G6 can be found, respectively, in the Panasonic GX7 Manual (free pdf) or the online Panasonic G6 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Panasonic GX7 or the Panasonic G6 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Panasonic Lumix DMC-GX7:

• Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 1440k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More compact: Is smaller (123x71mm vs 122x85mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More modern: Is somewhat more recent (announced 3 months after the G6).

Reasons to prefer the Panasonic Lumix DMC-G6:

• Better sound: Can connect to an external microphone for higher quality sound recording.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
• 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 April 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the GX7 emerges as the winner of the contest (8 : 6 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Panasonic GX7 and the Panasonic G6 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX7 or the G6. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
