Nikon D300S vs Panasonic GX800

The Nikon D300S and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were revealed to the public, respectively, in July 2009 and January 2017. The D300S is a DSLR, while the GX800 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D300S) and a Four Thirds (GX800) sensor. The Nikon has a resolution of 12.2 megapixels, whereas the Panasonic provides 15.8 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D300S and the Panasonic Lumix DMC-GX800? 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

The side-by-side display below illustrates the physical size and weight of the Nikon D300S and the Panasonic GX800. 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 size dimensions are rounded to the nearest millimeter.

The GX800 can be obtained in three different colors (black, silver, red), while the D300S is only available in black.

Compare D300S versus GX800 top
Comparison D300S or GX800 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX800 is considerably smaller (59 percent) than the Nikon D300S. Moreover, the GX800 is substantially lighter (71 percent) than the D300S. It is worth mentioning in this context that the D300S is splash and dust resistant, while the GX800 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D300S) and the Micro Four Thirds Lens Catalog (GX800). Mirrorless cameras, such as the GX800, 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 D300S gets 950 shots out of its EN-EL3e battery, while the GX800 can take 210 images on a single charge of its DMW-BLH7 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 GX800 was launched at a markedly lower price (by 69 percent) than the D300S, 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D300S features an APS-C sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D300S has a native 3:2 aspect ratio, while the one in the GX800 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Nikon D300S and Panasonic GX800 sensor measures

Despite having a smaller sensor, the GX800 offers a higher resolution of 15.8 megapixels, compared with 12.2 MP of the D300S. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 5.53μm for the D300S). However, it should be noted that the GX800 is much more recent (by 7 years and 5 months) than the D300S, 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 GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic GX800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX800 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Nikon D300S are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Nikon D300S has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Panasonic Lumix DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

D300S versus GX800 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX800 provides a better video resolution than the D300S. It can shoot movie footage at 4K/30p, while the Nikon is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D300S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Nikon D300S and Panasonic GX800 along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the D300S, but is missing on the GX800 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The GX800 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D300S does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GX800 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon D300S and the Panasonic GX800 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The D300S writes its imaging data to Compact Flash or SDXC cards, while the GX800 uses SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX800 only has one slot. The GX800 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D300S cannot take advantage of Ultra High Speed SD cards.

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 Nikon D300S and Panasonic Lumix DMC-GX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D300S has a hotshoe, while the GX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Nikon D300S (unlike the GX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The GX800 is a recent model that features in the current product line-up of Panasonic. In contrast, the D300S has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D300S was succeeded by the Nikon D500. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Panasonic websites.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Nikon D300S and the Panasonic GX800? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Nikon D300S:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/500s) to freeze action.
  • Longer lasting: Can take more shots (950 versus 210) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in July 2009).

ilogo

Advantages of the Panasonic Lumix DMC-GX800:

  • More detail: Has more megapixels (15.8 vs 12.2MP), which boosts linear resolution by 12%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 720/24p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (107x65mm vs 147x115mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 669g or 71 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
  • More modern: Reflects 7 years and 5 months of technical progress since the D300S launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GX800 is the clear winner of the contest (17 : 12 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

D300S 12:17 GX800

How about other alternatives? Do the specifications of the Nikon D300S and the Panasonic GX800 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D300S and the GX800 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
