Going beyond this snapshot of core features and characteristics, what are the differences between the Kodak PixPro S-1 and the Nikon D40X? 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 Kodak S-1 and the Nikon D40X is provided 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 dimensions are rounded to the nearest millimeter.

The S-1 can be obtained in two different colors (black, white), while the D40X is also available in two color-versions, but different ones (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40X is considerably larger (48 percent) than the Kodak S-1. Moreover, the D40X is substantially heavier (80 percent) than the S-1. In this context, it is worth noting that neither the S-1 nor the D40X are weather-sealed.

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 Micro Four Thirds Lens Catalog (S-1) and the Nikon Lens Catalog (D40X). Mirrorless cameras, such as the Kodak S-1, 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 S-1 gets 410 shots out of its Kodak LB-070 battery, while the D40X can take 520 images on a single charge of its Nikon EN-EL9 power pack. The power pack in the S-1 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The S-1 was launched at a markedly lower price (by 59 percent) than the D40X, 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Kodak S-1 features a Four Thirds sensor and the Nikon D40X an APS-C sensor. The sensor area in the D40X is 66 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the S-1 has a native 4:3 aspect ratio, while the one in the D40X offers a 3:2 aspect.

Despite having a smaller sensor, the Kodak S-1 offers a higher resolution of 16.1 megapixels, compared with 10 MP of the Nikon D40X. 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 3.74μm versus 6.11μm for the D40X). However, it should be noted that the S-1 is much more recent (by 4 years and 10 months) than the D40X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Kodak S-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S-1 for good quality output (200 dots per inch) amounts to 23.2 x 17.4 inches or 58.9 x 44.2 cm, for very good quality (250 dpi) 18.6 x 13.9 inches or 47.1 x 35.4 cm, and for excellent quality (300 dpi) 15.5 x 11.6 inches or 39.3 x 29.5 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.

The Kodak PixPro S-1 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Nikon D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the S-1 is build around a CMOS sensor, while the D40X uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. 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 S-1 indeed provides movie recording capabilities, while the D40X does not. The highest resolution format that the S-1 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the S-1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Kodak S-1 and Nikon D40X along with similar information for a selection of comparators.

One feature that differentiates the S-1 and the D40X is in-body image stabilization (IBIS). The S-1 reduces the risk of handshake-induced blur with all attached lenses, while the D40X offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The S-1 writes its imaging data to SDXC cards, while the D40X uses SDHC cards. The S-1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), 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 Kodak PixPro S-1 and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S-1 offers wifi support, while the D40X does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the S-1 and the D40X have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the S-1 does not have a direct successor. Further information on the features and operation of the S-1 and D40X can be found, respectively, in the Kodak S-1 Manual (free pdf) or the online Nikon D40X Manual.

Review summary

So how do things add up? Which of the two cameras – the Kodak S-1 or the Nikon D40X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Kodak PixPro S-1:

• More detail: Offers more megapixels (16.1 vs 10MP) with a 24% higher linear resolution.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (116x68mm vs 124x94mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 232g or 44 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More legacy lens friendly: Can take a broad range of 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 (59 percent cheaper at launch).
• More modern: Reflects 4 years and 10 months of technical progress since the D40X launch.

Arguments in favor of the Nikon D40X:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Gets more shots (520 versus 410) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More heavily discounted: Has been around for much longer (launched in March 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the S-1 is the clear winner of the match-up (16 : 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 before making a decision 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.

How about other alternatives? Do the specifications of the Kodak S-1 and the Nikon D40X place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 remains incomplete and does no justice, for example, to the way the S-1 or the D40X perform in practice. 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 expert reviews 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
