Body comparison

The physical size and weight of the Sony HX99 and the Sony RX0 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.

Size Sony HX99 vs Sony RX0
Compare HX99 versus RX0 top
Comparison HX99 or RX0 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX0 is considerably smaller (59 percent) than the Sony HX99. Moreover, the RX0 is substantially lighter (55 percent) than the HX99. It is noteworthy in this context that the RX0 is splash and dust-proof, while the HX99 does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

Concerning battery life, the HX99 gets 370 shots out of its Sony NP-BX1 battery, while the RX0 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 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 HX99 was launched at a markedly lower price (by 36 percent) than the RX0, 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony HX99 features a 1/2.3-inch sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 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 HX99 has a native 4:3 aspect ratio, while the one in the RX0 offers a 3:2 aspect.

Sony HX99 and Sony RX0 sensor measures

Despite having a smaller sensor, the Sony HX99 offers a higher resolution of 18 megapixels, compared with 15.4 MP of the Sony RX0. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.25μm versus 2.74μm for the RX0). However, it should be noted that the HX99 is a somewhat more recent model (by 1 year) than the RX0, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony HX99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX99 for good quality output (200 dots per inch) amounts to 24.5 x 18.4 inches or 62.2 x 46.6 cm, for very good quality (250 dpi) 19.6 x 14.7 inches or 49.7 x 37.3 cm, and for excellent quality (300 dpi) 16.3 x 12.2 inches or 41.5 x 31.1 cm. The corresponding values for the Sony RX0 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-HX99 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 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.

HX99 versus RX0 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait").

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 HX99 has one, while the RX0 does not. While the built-in flash of the HX99 is not very powerful, it can at times be useful as a fill-in light.

The HX99 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the RX0 does not have a selfie-screen.

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 RX0 only has 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 HX99 is equipped with a zoom lens, while the RX0 comes with a built-in prime. The HX99 has a 24-720mm f/3.5-6.4 optic and the RX0 offers a 24mm f/4.0 (focal lengths in full frame equivalent terms). Hence, the HX99 and RX0 provide the same view at the wide-angle end, but the RX0 has less tele-photo reach at the long end. The HX99 offers the faster maximum aperture.

The HX99 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the RX0 uses micro SDXC or Memory Stick Micro cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the RX0 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The HX99 does not feature such a mic input.

Both the HX99 and the RX0 have been discontinued, but can regularly be found used on ebay. The RX0 was replaced by the Sony RX0 II, while the HX99 does not have a direct successor. Further information on the features and operation of the HX99 and RX0 can be found, respectively, in the Sony HX99 Manual (free pdf) or the online Sony RX0 Manual.

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 5.5 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/3.5 vs f/4.0).
  • Longer lasting: Can take more shots (370 versus 240) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year after the RX0).


Advantages of the Sony Cyber-shot DSC-RX0:

  • 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.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (59x41mm vs 102x58mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 132g or 55 percent) and is thus easier to take along.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
  • More heavily discounted: Has been on the market for longer (launched in August 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the HX99 is the clear winner of the match-up (17 : 12 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

HX99 17:12 RX0

How about other alternatives? Do the specifications of the Sony HX99 and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the HX99 and the RX0 in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major 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 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.
