Nikon D850 versus Panasonic G9

The Nikon D850 and the Panasonic Lumix DC-G9 are two digital cameras that were officially introduced, respectively, in July 2017 and November 2017. The D850 is a DSLR, while the G9 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D850) and a Four Thirds (G9) sensor. The Nikon has a resolution of 45.4 megapixel, whereas the Panasonic 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: Nikon D850 vs Panasonic G9

The physical size and weight of the Nikon D850 and the Panasonic G9 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 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 D850 – 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 smaller (27 percent) than the Nikon D850. Moreover, the G9 is substantially lighter (35 percent) than the D850. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Nikon Lens Catalog (D850) and the Micro Four Thirds Lens Catalog (G9). Mirrorless cameras, such as the G9, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D850 gets 1840 shots out of its EN-EL15a battery, while the G9 can take 400 images on a single charge of its DMW-BLF19 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. 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 G9 was launched at a markedly lower price (by 48 percent) than the D850, 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: Nikon D850 vs Panasonic G9

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. 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.

Of the two cameras under consideration, the Nikon D850 features a full frame sensor and the Panasonic G9 a Four Thirds sensor. The sensor area in the G9 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D850 has a native 3:2 aspect ratio, while the one in the G9 offers a 4:3 aspect.

Nikon D850 and Panasonic G9 sensor measures

With 45.4MP, the D850 offers a higher resolution than the G9 (20.2MP), but the D850 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.34μm for the G9) due to its larger sensor. However, the G9 is a somewhat more recent model (by 3 months) than the D850, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

Unlike the D850, 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).

D850 versus G9 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9 provides a faster frame rate than the D850. It can shoot movie footage at 4K/60p, while the Nikon is limited to 4K/30p.

 

Feature comparison: Nikon D850 vs Panasonic G9

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G9 has an electronic viewfinder (3680k dots), while the D850 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Nikon D850 and Panasonic G9 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.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G9 features 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 D850 and the G9 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The D850 replaced the earlier Nikon D810, while the G9 followed on from the Panasonic G85.

Reasons to prefer the Panasonic Lumix DC-G9:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (20 vs 9 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (137x97mm vs 146x124mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 347g or 35 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
  • More modern: Was introduced somewhat (3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (12 : 7 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.

D850 07:12 G9

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D850 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 hands-on reviews by experts 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
