Going beyond this snapshot of core features and characteristics, what are the differences between the Kodak PixPro S-1 and the Nikon D90? 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 Kodak S-1 and the Nikon D90. 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 S-1 can be obtained in two different colors (black, white), while the D90 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D90 is considerably larger (72 percent) than the Kodak S-1. Moreover, the D90 is substantially heavier (142 percent) than the S-1. In this context, it is worth noting that neither the S-1 nor the D90 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 (D90). 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 D90 can take 850 images on a single charge of its Nikon EN-EL3e 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.

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 S-1 was launched at a markedly lower price (by 77 percent) than the D90, 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 size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to 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 D90 an APS-C sensor. The sensor area in the D90 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 D90 offers a 3:2 aspect.

Despite having a smaller sensor, the Kodak S-1 offers a higher resolution of 16.1 megapixels, compared with 12.2 MP of the Nikon D90. 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 5.53μm for the D90). However, it should be noted that the S-1 is much more recent (by 3 years and 4 months) than the D90, 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 D90 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 Kodak PixPro S-1 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S-1 provides a higher video resolution than the D90. It can shoot video footage at 1080/30p, 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 D90 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 table below summarizes some of the other core capabilities of the Kodak S-1 and Nikon D90 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the S-1 and the D90 is in-body image stabilization (IBIS). The S-1 reduces the risk of handshake-induced blur with all attached lenses, while the D90 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 D90 uses SDHC cards. The S-1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D90 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 D90 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 D90 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the S-1 and the D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the S-1 does not have a direct successor. Further information on the features and operation of the S-1 and D90 can be found, respectively, in the Kodak S-1 Manual (free pdf) or the online Nikon D90 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Kodak S-1 or the Nikon D90 – 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 12.2MP) with a 13% higher linear resolution.
• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• 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.
• More compact: Is smaller (116x68mm vs 132x103mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 413g or 59 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 (77 percent cheaper at launch).
• More modern: Reflects 3 years and 4 months of technical progress since the D90 launch.

Reasons to prefer the Nikon D90:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster burst: Shoots at higher frequency (4.5 vs 4 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (850 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 August 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the S-1 emerges as the winner of the contest (13 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

How about other alternatives? Do the specifications of the Kodak S-1 and the Nikon D90 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the S-1 and the D90 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 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
