Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G5 and the Panasonic Lumix DMC-GF5? 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

An illustration of the physical size and weight of the Panasonic G5 and the Panasonic GF5 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The G5 can be obtained in two different colors (black, silver), while the GF5 is available in three color-versions (black, red, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF5 is notably smaller (27 percent) than the Panasonic G5. Moreover, the GF5 is markedly lighter (33 percent) than the G5. In this context, it is worth noting that neither the G5 nor the GF5 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 G5 gets 320 shots out of its Panasonic DMW-BLC12 battery, while the GF5 can take 360 images on a single charge of its Panasonic DMW-BLE9 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GF5 was launched at a somewhat lower price (by 17 percent) than the G5, 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

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 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. 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 associated with larger, more expensive camera bodies 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 G5 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the GF5. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the G5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.33μm for the GF5). In this context, it should be noted, however, that the G5 is a somewhat more recent model (by 3 months) than the GF5, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The resolution advantage of the Panasonic G5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G5 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Panasonic GF5 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Panasonic Lumix DMC-G5 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GF5 are ISO 160 to ISO 6400, with the possibility to increase the ISO range to 160-12800.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 G5 provides substantially higher image quality than the GF5, with an overall score that is 11 points higher. This advantage is based on 0.9 bits higher color depth, 1.6 EV in additional dynamic range, and 0.1 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G5 provides a higher frame rate than the GF5. It can shoot video footage at 1080/60p, while the GF5 is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G5 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF5 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic G5 and Panasonic GF5 along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the G5 and the GF5 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-G5 and Panasonic Lumix DMC-GF5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G5 has a hotshoe, while the GF5 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G5 and the GF5 have been discontinued, but can regularly be found used on ebay. The GF5 was replaced by the Panasonic GF6, while the G5 was followed by the Panasonic G6. Further information on the features and operation of the G5 and GF5 can be found, respectively, in the Panasonic G5 Manual (free pdf) or the online Panasonic GF5 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic G5 and the Panasonic GF5? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Panasonic Lumix DMC-G5:

• More detail: Offers more megapixels (15.9 vs 12MP) with a 15% higher linear resolution.
• Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (1.6 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• 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 (6 vs 4 flaps/sec) to capture the decisive moment.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Is somewhat more recent (announced 3 months after the GF5).

Advantages of the Panasonic Lumix DMC-GF5:

• More compact: Is smaller (108x67mm vs 120x83mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 129g or 33 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (360 versus 320) out of a single battery charge.
• More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in April 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the G5 is the clear winner of the match-up (10 : 5 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. 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 G5 and the Panasonic GF5 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G5 and the GF5 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
