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 HX99 was launched at a markedly lower price (by 63 percent) than the RX100 VI, 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.
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 are more costly to manufacture and tend to 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 RX100 VI an one-inch sensor. The sensor area in the RX100 VI 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 RX100 VI offers a 3:2 aspect.
With 20MP, the RX100 VI offers a higher resolution than the HX99 (18MP), but the RX100 VI nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.25μm for the HX99) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 RX100 VI implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 VI 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 HX99 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 RX100 VI has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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-RX100 VI are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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"). 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 also of capturing video footage. 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).
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the RX100 VI offers a substantially higher resolution than the one in the HX99 (2359k vs 638k dots). The following table reports on some other key feature differences and similarities of the Sony HX99, the Sony RX100 VI, and comparable cameras.

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 RX100 VI 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).
Both the HX99 and the RX100 VI have zoom lenses built in. The HX99 has a 24-720mm f/3.5-6.4 optic and the RX100 VI offers a 24-200mm f/2.8-4.5 (focal lengths in full frame equivalent terms). Hence, the HX99 and RX100 VI provide the same view at the wide-angle end, but the RX100 VI has less tele-photo reach at the long end. The RX100 VI offers the faster maximum aperture.
Concerning the storage of imaging data, both the HX99 and the RX100 VI write their files to SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-HX99 and Sony Cyber-shot DSC-RX100 VI and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The HX99 is a recent model that features in the current product line-up of Sony. In contrast, the RX100 VI has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 VI was succeeded by the Sony RX100 VII. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So what conclusions can be drawn? Which of the two cameras – the Sony HX99 or the Sony RX100 VI – 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.
Arguments in favor of the Sony Cyber-shot DSC-HX99:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Less heavy: Is lighter (by 59g or 20 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (370 versus 240) on a single battery charge.
- More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
Reasons to prefer the Sony Cyber-shot DSC-RX100 VI:
- 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.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 638k dots).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
- Faster burst: Shoots at higher frequency (24 vs 10 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.5).
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 VI is the clear winner of the contest (12 : 5 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 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 HX99 and the Sony RX100 VI 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 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 HX99 or the RX100 VI perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The above review scores should be interpreted with care, 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 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.
