Nikon D40X vs Panasonic S1

The Nikon D40X and the Panasonic Lumix DC-S1 are two digital cameras that were revealed to the public, respectively, in March 2007 and February 2019. The D40X is a DSLR, while the S1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40X) and a full frame (S1) sensor. The Nikon has a resolution of 10 megapixels, whereas the Panasonic provides 24 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 D40X and the Panasonic Lumix DC-S1? 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

An illustration of the physical size and weight of the Nikon D40X and the Panasonic S1 is provided 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.

The D40X can be obtained in two different colors (black, silver), while the S1 is only available in black.

Comparison D40X or S1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 is notably larger (41 percent) than the Nikon D40X. Moreover, the S1 is substantially heavier (95 percent) than the D40X. It is noteworthy in this context that the S1 is splash and dust-proof, while the D40X 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the D40X gets 520 shots out of its EN-EL9 battery, while the S1 can take 400 images on a single charge of its DMW-BLJ31 power pack. The power pack in the S1 can be charged via the USB port, which can be very convenient when travelling.

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

Any camera decision 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 D40X was launched at a markedly lower price (by 71 percent) than the S1, 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.

 

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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D40X features an APS-C sensor and the Panasonic S1 a full frame sensor. The sensor area in the S1 is 127 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D40X and Panasonic S1 sensor measures

With 24MP, the S1 offers a higher resolution than the D40X (10MP), but the S1 has smaller individual pixels (pixel pitch of 5.94μm versus 6.11μm for the D40X). Yet, the S1 is a much more recent model (by 11 years and 11 months) than the D40X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.

Unlike the D40X, the S1 has the capacity to capture high quality composite images (96MP) 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).

The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DC-S1 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

D40X versus S1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under consideration, the S1 offers substantially better image quality than the D40X (overall score 32 points higher). The advantage is based on 2.8 bits higher color depth, 3.1 EV in additional dynamic range, and 2.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The S1 indeed provides for movie recording, while the D40X does not. The highest resolution format that the S1 can use is 4K/60p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the S1 has an electronic viewfinder (5760k dots), while the D40X 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 viewfinder in the S1 offers a wider field of view (100%) than the one in the D40X (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the S1 has a higher magnification (0.78x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D40X and Panasonic S1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D40X has one, while the S1 does not. While the built-in flash of the D40X is not very powerful, it can at times be useful as a fill-in light.

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 S1 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 D40X writes its imaging data to SDHC cards, while the S1 uses SDHC or XQD cards. The S1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X only has one slot. The S1 supports UHS-II cards (on both slots), while the D40X 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 D40X and Panasonic Lumix DC-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40X does not offer wifi capability.

Studio photographers will appreciate that the Panasonic S1 (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1 is a recent model that features in the current product line-up of Panasonic. In contrast, the D40X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D40X was succeeded by the Nikon D60 . 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 is the bottom line? Is the Nikon D40X better than the Panasonic S1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (9 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • 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.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards on both slots.
  • More modern: Reflects 11 years and 11 months of technical progress since the D40X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the S1 is the clear winner of the contest (29 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

D40X 08:29 S1

How about other alternatives? Do the specifications of the Nikon D40X and the Panasonic S1 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 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 D40X or the S1 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.

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
