Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-HX99 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

The side-by-side display below illustrates the physical size and weight of the Sony HX99 and the Zeiss ZX1. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 (123 percent) than the Sony HX99. Moreover, the ZX1 is substantially heavier (231 percent) than the HX99. In this context, it is worth noting that neither the HX99 nor the ZX1 are weather-sealed.

Concerning battery life, the HX99 gets 370 shots out of its Sony NP-BX1 battery, while the ZX1 can take 250 images on a single charge of its Zeiss DD-PS1A power pack. The power pack in the HX99 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 HX99 was launched at a markedly lower price (by 93 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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 Zeiss ZX1 a full frame sensor. The sensor area in the ZX1 is 2986 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the HX99 has a native 4:3 aspect ratio, while the one in the ZX1 offers a 3:2 aspect.

With 37.4MP, the ZX1 offers a higher resolution than the HX99 (18MP), but the ZX1 nevertheless has larger individual pixels (pixel pitch of 4.81μm 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 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 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 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 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 cannot only take still pictures, but also record videos. 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. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the ZX1 offers a substantially higher resolution than the one in the HX99 (6221k vs 638k dots).

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 ZX1 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 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 ZX1 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).

The HX99 is equipped with a zoom lens, while the ZX1 comes with a built-in prime. The HX99 has a 24-720mm f/3.5-6.4 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 at the short end, as well as more tele-photo reach at the long end than the Zeiss. The ZX1 offers the faster maximum aperture.

The HX99 writes its imaging data to SDXC or Memory Stick PRO Duo 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-HX99 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 ZX1 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The HX99 does not feature such an accessory-socket.

Both the HX99 and the ZX1 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Sony and Zeiss. Further information on the features and operation of the HX99 and ZX1 can be found, respectively, in the Sony HX99 Manual (free pdf) or the online Zeiss ZX1 Manual.

Review summary

So what conclusions can be drawn? Is the Sony HX99 better than the Zeiss ZX1 or vice versa? 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 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 shutter: Has higher mechanical shutter speed (1/2000s vs 1/1000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 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 (102x58mm vs 142x93mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 558g or 70 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (370 versus 250) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• More affordable: Was introduced into a lower priced category (93 percent cheaper at launch).

Advantages of the Zeiss ZX1:

• More detail: Has more megapixels (37.4 vs 18MP), which boosts linear resolution by 47%.
• 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 viewfinder: Has higher resolution electronic viewfinder (6221k vs 638k dots).
• Larger screen: Has a bigger rear LCD (4.3" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2765k vs 922k dots).
• 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).
• 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).
• More prestigious: Has the Zeiss luxury appeal, which ensures a high resale value.

If the count of individual advantages (bullet points above) is taken as a guide, the ZX1 comes out slightly ahead of the HX99 (14 : 13 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Zeiss ZX1 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the HX99 or the ZX1. 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 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
