Panasonic G7 versus Panasonic G6

The Panasonic Lumix DMC-G7 and the Panasonic Lumix DMC-G6 are two digital cameras that were announced, respectively, in May 2015 and April 2013. Both the G7 and the G6 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G7 has a resolution of 15.8 megapixel, whereas the G6 provides 15.9 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 G7 vs Panasonic G6

The side-by-side display below illustrates the physical size and weight of the Panasonic G7 and the Panasonic G6. 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 G7 – 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 G6 is somewhat smaller (4 percent) than the Panasonic G7. Moreover, the G6 is markedly lighter (5 percent) than the G7. In this context, it is worth noting that neither the G7 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 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 G6 was somewhat cheaper (by 8 percent) than the G7 at launch, but both cameras fall into the same price category. 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 G7 vs Panasonic G6

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 tend 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.

Panasonic G7 and Panasonic G6 sensor measures

While the two cameras under review share the same sensor size, the G6 offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the G7. This megapixel 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 G7). Moreover, it should be noted, that the G7 is much more recent (by 2 years) than the G6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

G7 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.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7 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 G7 vs Panasonic G6

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 G7 offers a substantially higher resolution than the one in the G6 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Panasonic G7 and Panasonic G6 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G7 and the G6 have been discontinued, but can regularly be found used on eBay. The G6 was replaced by the Panasonic G7, while the G7 was followed by the Panasonic G85.

Review summary: Panasonic G7 vs Panasonic G6

So what is the bottom line? Which of the two cameras – the Panasonic G7 or the Panasonic G6 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Panasonic Lumix DMC-G7:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More modern: Reflects 2 years of technical progress since the G6 launch.


Reasons to prefer the Panasonic Lumix DMC-G6:

  • More heavily discounted: Has been around for much longer (launched in April 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the G7 emerges as the winner of the contest (3 : 1 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G7 03:01 G6

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 handling experience and imaging performance when actually working with the G7 or the G6. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
