Going beyond this snapshot of core features and characteristics, what are the differences between the Kodak PixPro S-1 and the Panasonic Lumix DMC-GX7? 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 Panasonic GX7. 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 GX7 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 Panasonic GX7 is notably larger (11 percent) than the Kodak S-1. Moreover, the GX7 is substantially heavier (39 percent) than the S-1. In this context, it is worth noting that neither the S-1 nor the GX7 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the S-1 gets 410 shots out of its Kodak LB-070 battery, while the GX7 can take 350 images on a single charge of its Panasonic DMW-BLG10 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 S-1 was launched at a markedly lower price (by 70 percent) than the GX7, 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 imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies 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 slightly higher resolution of 16.1 megapixels, compared with 15.8 MP of the GX7. This megapixels advantage translates into a 1 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 3.77μm for the GX7). Moreover, it should be noted that the GX7 is a somewhat more recent model (by 1 year and 6 months) than the S-1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

The Kodak PixPro S-1 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GX7 are ISO 125 to ISO 25600 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX7 provides a faster frame rate than the S-1. It can shoot movie footage at 1080/60p, while the Kodak is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the S-1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Kodak S-1, the Panasonic GX7, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX7 has a touchscreen, while the S-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 GX7 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 Panasonic GX7 has 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.

Concerning the storage of imaging data, both the S-1 and the GX7 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Panasonic Lumix DMC-GX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the S-1 and the GX7 have been discontinued, but can regularly be found used on ebay. The GX7 was replaced by the Panasonic GX85, while the S-1 does not have a direct successor. Further information on the features and operation of the S-1 and GX7 can be found, respectively, in the Kodak S-1 Manual (free pdf) or the online Panasonic GX7 Manual.

Review summary

So how do things add up? Which of the two cameras – the Kodak S-1 or the Panasonic GX7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Kodak PixPro S-1:

• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Less heavy: Is lighter (by 112g or 28 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (410 versus 350) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in January 2012).

Arguments in favor of the Panasonic Lumix DMC-GX7:

• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• 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 (5 vs 4 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the GX7 is the clear winner of the contest (11 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Panasonic GX7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 S-1 or the GX7 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
