Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-HX90V and the Sony Cyber-shot DSC-RX100 II? 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 Sony HX90V and the Sony RX100 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 dimensions are rounded to the nearest millimeter.

In this particular case, the Sony HX90V and the Sony RX100 II have exactly the same width and height, and, thus, have identically-sized bodies. However, the RX100 II is markedly heavier (15 percent) than the HX90V. In this context, it is worth noting that neither the HX90V nor the RX100 II are weather-sealed.

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.

The price is, of course, an important factor in any camera decision. 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 HX90V was launched at a markedly lower price (by 43 percent) than the RX100 II, 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony HX90V features a 1/2.3-inch sensor and the Sony RX100 II an one-inch sensor. The sensor area in the RX100 II is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the HX90V has a native 4:3 aspect ratio, while the one in the RX100 II offers a 3:2 aspect.

With 20MP, the RX100 II offers a higher resolution than the HX90V (18MP), but the RX100 II nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.25μm for the HX90V) due to its larger sensor. However, the HX90V is a somewhat more recent model (by 1 year and 9 months) than the RX100 II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the HX90V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX100 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Sony HX90V are 24.5 x 18.4 inches or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inches or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inches or 41.5 x 31.1 cm for excellent quality prints.

The Sony Cyber-shot DSC-HX90V has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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 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 cannot only take still pictures, but also record videos. 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 (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the HX90V has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX100 II relies on live view and the rear LCD for framing. That said, the RX100 II can be equipped with an optional viewfinder – the FDA-EV1MK. The following table reports on some other key feature differences and similarities of the Sony HX90V, the Sony RX100 II, and comparable cameras.

Both the HX90V and the RX100 II have zoom lenses built in. The HX90V has a 24-720mm f/3.5-6.4 optic and the RX100 II offers a 28-100mm f/1.8-4.9 (focal lengths in full frame equivalent terms). Hence, the HX90V provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the RX100 II. The RX100 II offers the faster maximum aperture.

Concerning the storage of imaging data, both the HX90V and the RX100 II write their files to SDXC or Memory Stick PRO Duo cards. The HX90V supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX100 II 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 Sony Cyber-shot DSC-HX90V and Sony Cyber-shot DSC-RX100 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX100 II has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The HX90V does not feature such an accessory-socket.

Travel and landscape photographers will find it useful that the HX90V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the HX90V and the RX100 II have been discontinued, but can regularly be found used on ebay. The RX100 II was replaced by the Sony RX100 III, while the HX90V was followed by the Sony HX99. Further information on the features and operation of the HX90V and RX100 II can be found, respectively, in the Sony HX90V Manual (free pdf) or the online Sony RX100 II Manual.

Review summary

So what conclusions can be drawn? Is the Sony HX90V better than the Sony RX100 II or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Sony Cyber-shot DSC-HX90V:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Less heavy: Is lighter (by 36g or 13 percent) and hence easier to carry around.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 9 months after the RX100 II).

Reasons to prefer the Sony Cyber-shot DSC-RX100 II:

• More detail: Has more megapixels (20 vs 18MP), which boosts linear resolution by 7%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 921k dots).
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.5).
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been on the market for longer (launched in June 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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 HX90V and the Sony RX100 II place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom 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 HX90V or the RX100 II perform in practice. 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
