Panasonic G5 versus Panasonic G9

The Panasonic Lumix DMC-G5 and the Panasonic Lumix DC-G9 are two digital cameras that were officially introduced, respectively, in July 2012 and November 2017. Both the G5 and the G9 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G5 has a resolution of 15.9 megapixel, whereas the G9 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 G5 vs Panasonic G9

An illustration of the physical size and weight of the Panasonic G5 and the Panasonic G9 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 side – the G5 – 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 G9 is notably larger (33 percent) than the Panasonic G5. Moreover, the G9 is substantially heavier (66 percent) than the G5. It is noteworthy in this context that the G9 is splash and dust-proof, while the G5 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 G5 gets 320 shots out of its DMW-BLC12 battery, while the G9 can take 400 images on a single charge of its DMW-BLF19 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 G5 was launched at a markedly lower price (by 65 percent) than the G9, 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 G5 vs Panasonic G9

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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 G5 and Panasonic G9 sensor measures

While the two cameras under review share the same sensor size, the G9 offers a higher resolution of 20.2 megapixel, compared with 15.9 MP of the G5. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the G9 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 G5). However, it should be noted that the G9 is much more recent (by 5 years and 3 months) than the G5, 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 G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the G5, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

G5 versus G9 MP

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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 G9 provides a better video resolution than the G5. It can shoot movie footage at 4K/60p, while the G5 is limited to 1080/60p.

 

Feature comparison: Panasonic G5 vs Panasonic G9

Beyond 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 G9 offers a substantially higher resolution than the one in the G5 (3680k vs 1440k dots). The table below summarizes some of the other core capabilities of the Panasonic G5 and Panasonic G9 in connection with corresponding information for a sample of similar cameras.

The G9 is a current model that online retailers, such as amazon, will have in stock. In contrast, the G5 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G5 was succeeded by the Panasonic G6.

Review summary: Panasonic G5 vs Panasonic G9

So what conclusions can be drawn? Which of the two cameras – the Panasonic G5 or the Panasonic G9 – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Panasonic Lumix DMC-G5:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (120x83mm vs 137x97mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 262g or 40 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in July 2012).


Advantages of the Panasonic Lumix DC-G9:

  • 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.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 1440k dots).
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 6 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (400 versus 320) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Reflects 5 years and 3 months of technical progress since the G5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (13 : 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.

G5 06:13 G9

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G5 or the G9 handle or perform in practice. 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.

The review scores listed above should be treated 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. 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.
