Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX0II and the Zeiss ZX1? 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 Sony RX0 II and the Zeiss ZX1 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 width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Zeiss ZX1 is considerably larger (446 percent) than the Sony RX0 II. Moreover, the ZX1 is substantially heavier (506 percent) than the RX0 II. It is worth mentioning in this context that the RX0 II is splash and dust resistant, while the ZX1 does not feature any corresponding weather-sealing. More than that, the RX0 II is water-proof up to 10m and can, thus, be used for underwater photography.

Concerning battery life, the RX0 II gets 240 shots out of its Sony NP-BJ1 battery, while the ZX1 can take 250 images on a single charge of its Zeiss DD-PS1A power pack. The power pack in the RX0 II 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The RX0 II was launched at a markedly lower price (by 88 percent) than the ZX1, 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. 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.

Of the two cameras under consideration, the Sony RX0 II features an one-inch sensor and the Zeiss ZX1 a full frame sensor. The sensor area in the ZX1 is 645 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 37.4MP, the ZX1 offers a higher resolution than the RX0 II (15.4MP), but the ZX1 nevertheless has larger individual pixels (pixel pitch of 4.81μm versus 2.74μm for the RX0 II) due to its larger sensor. However, the RX0 II is a somewhat more recent model (by 5 months) than the ZX1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Zeiss ZX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZX1 for good quality output (200 dots per inch) amounts to 37.4 x 25 inches or 95.1 x 63.4 cm, for very good quality (250 dpi) 30 x 20 inches or 76.1 x 50.7 cm, and for excellent quality (300 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm. The corresponding values for the Sony RX0 II are 24 x 16 inches or 61 x 40.6 cm for good quality, 19.2 x 12.8 inches or 48.8 x 32.5 cm for very good quality, and 16 x 10.7 inches or 40.6 x 27.1 cm for excellent quality prints.

The Sony Cyber-shot DSC-RX0II has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Zeiss ZX1 are ISO 80 to ISO 51200 (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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the ZX1 has an electronic viewfinder (6221k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX0 II relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony RX0 II, the Zeiss ZX1, 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 ZX1 has a touchscreen, while the RX0 II 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, both cameras under consideration feature an 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).

Both the RX0 II and the ZX1 have built-in prime lenses. The RX0 II has a 24mm f/4.0 optic and the ZX1 offers a 35mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view than the Zeiss. The ZX1 offers the faster maximum aperture.

The RX0 II writes its imaging data to micro SDXC or Memory Stick Micro cards, while the ZX1 uses an internal SSD.

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 Sony Cyber-shot DSC-RX0II and Zeiss ZX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 II has a microphone port, which is missing on the ZX1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The RX0 II is a recent model that features in the current product line-up of Sony. In contrast, the ZX1 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the ZX1 from Zeiss. Further information on the features and operation of the RX0 II and ZX1 can be found, respectively, in the Sony RX0 II Manual (free pdf) or the online Zeiss ZX1 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Sony RX0 II and the Zeiss ZX1? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Sony Cyber-shot DSC-RX0II:

• Better sound: Can connect to an external microphone for higher quality sound recording.
• 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 (5.5 vs 3 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (59x41mm vs 142x93mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 668g or 83 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 5 months after the ZX1).

Reasons to prefer the Zeiss ZX1:

• More detail: Has more megapixels (37.4 vs 15.4MP), which boosts linear resolution by 56%.
• 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 electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (4.3" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2765k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/4.0).
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More prestigious: Has the Zeiss luxury appeal, which ensures a high resale value.

If the count of relative strengths (bullet points above) is taken as a measure, the ZX1 emerges as the winner of the match-up (15 : 12 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 Sony RX0 II and the Zeiss ZX1 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera listing 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 says little about, for example, the shooting experience and imaging performance of the RX0 II and the ZX1 in practical situations. 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 (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.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
