Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z50 and the Sony Cyber-shot DSC-RX0II? 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 Nikon Z50 and the Sony RX0 II. 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 measures 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 Sony RX0 II is considerably smaller (80 percent) than the Nikon Z50. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, the RX0 II is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 II has a lens built in, whereas the Z50 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the Z50 gets 320 shots out of its Nikon EN-EL25 battery, while the RX0 II can take 240 images on a single charge of its Sony NP-BJ1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX0 II was launched at a lower price than the Z50, despite having a lens built in. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Nikon Z50 features an APS-C sensor and the Sony RX0 II an one-inch sensor. The sensor area in the RX0 II is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 20.7MP, the Z50 offers a higher resolution than the RX0 II (15.4MP), but the Z50 nevertheless has larger individual pixels (pixel pitch of 4.22μm versus 2.74μm for the RX0 II) due to its larger sensor. Moreover, the Z50 is a somewhat more recent model (by 6 months) than the RX0 II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the Z50 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Z50 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z50 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 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 Z50 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Z50 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 100-204800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0II are ISO 80 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for 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 Z50 has an electronic viewfinder (2360k 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 table below summarizes some of the other core capabilities of the Nikon Z50 and Sony RX0 II in connection with corresponding information for a sample of similar cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The Z50 has one, while the RX0 II does not. While the built-in flash of the Z50 is not very powerful, it can at times be useful as a fill-in light.

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).

The Nikon Z50 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.

The Z50 writes its imaging data to SDXC cards, while the RX0 II uses micro SDXC or Memory Stick Micro cards. The Z50 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX0 II can use UHS-I cards (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 Nikon Z50 and Sony Cyber-shot DSC-RX0II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z50 has a hotshoe, while the RX0 II does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the Z50 and the RX0 II are recent models that are part of the current product line-up. The RX0 II replaced the earlier Sony RX0, while the Z50 does not have a direct predecessor. Further information on the features and operation of the Z50 and RX0 II can be found, respectively, in the Nikon Z50 Manual (free pdf) or the online Sony RX0 II Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon Z50 and the Sony RX0 II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Nikon Z50:

• More detail: Offers more megapixels (20.7 vs 15.4MP) with a 16% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.2" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (11 vs 5.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (320 versus 240) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Is somewhat more recent (announced 6 months after the RX0 II).

Reasons to prefer the Sony Cyber-shot DSC-RX0II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Ready to shoot: Has an integrated lens, whereas the Z50 necessitates an extra lens.
• More compact: Is smaller (59x41mm vs 127x94mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the Z50).
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in March 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the Z50 is the clear winner of the match-up (19 : 7 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 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 Nikon Z50 and the Sony RX0 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 Z50 or the RX0 II 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 why hands-on reviews by experts are important. 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
