Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-420 and the Kodak PixPro S-1? 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 physical size and weight of the Olympus E-420 and the Kodak S-1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The S-1 can be obtained in two different colors (black, white), while the E-420 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 Kodak S-1 is considerably smaller (33 percent) than the Olympus E-420. Moreover, the S-1 is markedly lighter (34 percent) than the E-420. In this context, it is worth noting that neither the E-420 nor the S-1 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-420) and the Micro Four Thirds Lens Catalog (S-1). Mirrorless cameras, such as the S-1, 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 E-420 gets 500 shots out of its Olympus BLS-1 battery, while the S-1 can take 410 images on a single charge of its Kodak LB-070 power pack. The power pack in the S-1 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 50 percent) than the E-420, 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the S-1 offers a higher resolution of 16.1 megapixels, compared with 10 MP of the E-420. This megapixels advantage translates into a 27 percent gain in linear resolution. On the other hand, these sensor specs imply that the S-1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.74μm versus 4.74μm for the E-420). However, it should be noted that the S-1 is much more recent (by 3 years and 10 months) than the E-420, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

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 Olympus E-420 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-420 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Kodak PixPro S-1 are ISO 200 to ISO 12800 (no boost).

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 cannot only take still pictures, but also record videos. The S-1 indeed provides for movie recording, while the E-420 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 variety of features. For example, the E-420 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 Olympus E-420 and Kodak S-1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-420 has one, while the S-1 does not. While the built-in flash of the E-420 is not very powerful, it can at times be useful as a fill-in light.

The E-420 writes its imaging data to Compact Flash or xD Picture cards, while the S-1 uses SDXC cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the S-1 only has one slot.

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 Olympus E-420 and Kodak PixPro S-1 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, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-420 does not provide wifi capability.

Both the E-420 and the S-1 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Olympus and Kodak. Further information on the features and operation of the E-420 and S-1 can be found, respectively, in the Olympus E-420 Manual (free pdf) or the online Kodak S-1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-420 or the Kodak S-1 – 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.

Reasons to prefer the Olympus E-420:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Can take more shots (500 versus 410) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• 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 March 2008).

Advantages of the Kodak PixPro S-1:

• More detail: Has more megapixels (16.1 vs 10MP), which boosts linear resolution by 27%.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 215k 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 3.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (116x68mm vs 130x91mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 150g or 34 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More modern: Reflects 3 years and 10 months of technical progress since the E-420 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the S-1 is the clear winner of the contest (15 : 5 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 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 Olympus E-420 and the Kodak S-1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-420 or the S-1 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 where reviews by experts come in. 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.

Note: (+ +) 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
