Panasonic G9 versus Sony RX100 V

The Panasonic Lumix DC-G9 and the Sony Cyber-shot DSC-RX100 V are two digital cameras that were revealed to the public, respectively, in November 2017 and October 2016. The G9 is a mirrorless interchangeable lens camera, while the RX100 V is a fixed lens compact. The cameras are based on a Four Thirds (G9) and an one-inch (RX100 V) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Sony provides 20 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 G9 vs Sony RX100 V

The physical size and weight of the Panasonic G9 and the Sony RX100 V are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions 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 – the G9 – represents 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 Sony RX100 V is considerably smaller (55 percent) than the Panasonic G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the RX100 V does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens build in, whereas the G9 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the G9 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the RX100 V can take 220 images on a single charge of its NP-BX1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera purchase will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 V was launched at a lower price than the G9, despite having a lens build in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison: Panasonic G9 vs Sony RX100 V

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the G9 has a native 4:3 aspect ratio, while the one in the RX100 V offers a 3:2 aspect.

Panasonic G9 and Sony RX100 V sensor measures

With 20.2MP, the G9 offers a slightly higher resolution than the RX100 V (20MP), but the G9 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 V) due to its larger sensor. Moreover, the G9 is a somewhat more recent model (by 1 year and 1 month) than the RX100 V, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 RX100 V, 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).

G9 versus RX100 V MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G9 and the RX100 V are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The RX100 V replaced the earlier Sony RX100 IV, while the G9 followed on from the Panasonic G85.

Review summary: Panasonic G9 vs Sony RX100 V

So what conclusions can be drawn? Which of the two cameras – the Panasonic G9 or the Sony RX100 V – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Panasonic Lumix DC-G9:

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX100 V:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (24 vs 20 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the G9 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the G9).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More heavily discounted: Has been on the market for longer (launched in October 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (13 : 9 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.

G9 13:09 RX100 V

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G9 and the RX100 V in practical situations. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
