Panasonic G9 versus Nikon D3S

The Panasonic Lumix DC-G9 and the Nikon D3S are two digital cameras that were officially introduced, respectively, in November 2017 and October 2009. The G9 is a mirrorless interchangeable lens camera, while the D3S is a DSLR. The cameras are based on a Four Thirds (G9) and a full frame sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Nikon provides 12.1 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Nikon D3S. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth 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 – the G9 – represents the basis or 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 Nikon D3S is considerably larger (89 percent) than the Panasonic G9. Moreover, the D3S is substantially heavier (88 percent) than the G9. 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 Micro Four Thirds Lens Catalog (G9) and the Nikon Lens Catalog (D3S). Mirrorless cameras, such as the Panasonic G9, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the D3S can take 4200 images on a single charge of its EN-EL4a 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9 was launched at a markedly lower price (by 67 percent) than the D3S, 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

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Nikon D3S a full frame sensor. The sensor area in the D3S is 282 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the G9 has a native 4:3 aspect ratio, while the one in the D3S offers a 3:2 aspect.

Panasonic G9 and Nikon D3S sensor measures
Sensor size

Despite having a smaller sensor, the Panasonic G9 offers a higher resolution of 20.2 megapixel, compared with 12.1 MP of the Nikon D3S. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 8.43μm for the D3S). However, it should be noted that the G9 is much more recent (by 8 years) than the D3S, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 D3S, 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).

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G9 provides a higher video resolution than the D3S. It can shoot video footage at 4K/60p, while the Nikon is limited to 720/24p.

Feature comparison

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 D3S 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 adjacent table lists some of the other core features of the Panasonic G9 and Nikon D3S along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The G9 is a current model that online retailers, such as amazon, will have in stock. In contrast, the D3S has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the D3S was succeeded by the Nikon D4.

Summary

So how do things add up? Is there a clear favorite between the Panasonic G9 and the Panasonic G9? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of the Panasonic Lumix DC-G9:

  • More detail: Offers more megapixels (20.2 vs 12.1MP) with a 27% higher linear resolution.
  • 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 720/24p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (20 vs 11 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (137x97mm vs 160x157mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 582g or 47 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
  • More modern: Reflects 8 years of technical progress since the D3S launch.

Arguments in favor of the Nikon D3S:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Gets more shots (4200 versus 400) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in October 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (15 : 4 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.

G9 15:04 D3S

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 D3S 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. 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. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
