Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-HX99 and the Panasonic Lumix DC-TZ90? 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 physical size and weight of the Sony HX99 and the Panasonic TZ90 are illustrated in the side-by-side display below. 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.

The TZ90 can be obtained in two different colors (black, silver), while the HX99 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ90 is notably larger (27 percent) than the Sony HX99. Moreover, the TZ90 is markedly heavier (33 percent) than the HX99. In this context, it is worth noting that neither the HX99 nor the TZ90 are weather-sealed.

Concerning battery life, the HX99 gets 370 shots out of its Sony NP-BX1 battery, while the TZ90 can take 380 images on a single charge of its Panasonic DMW-BLG10 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 two cameras under review were launched at the same price and fall into the same 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the TZ90 offers a higher resolution of 20.2 megapixels, compared with 18 MP of the HX99. This megapixels advantage translates into a 6 percent gain in linear resolution. On the other hand, these sensor specs imply that the TZ90 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.25μm for the HX99). Moreover, it should be noted, that the HX99 is a somewhat more recent model (by 1 year and 4 months) than the TZ90, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Panasonic TZ90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ90 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 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 Panasonic Lumix DC-TZ90 offers exactly the same ISO settings.

In terms of underlying technology, the HX99 is build around a CMOS sensor, while the TZ90 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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).

Feature comparison

Beyond 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 TZ90 offers a substantially higher resolution than the one in the HX99 (1166k vs 638k dots).

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

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 TZ90 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 TZ90 have zoom lenses built in. The HX99 has a 24-720mm f/3.5-6.4 optic and the TZ90 offers a 24-720mm f/3.3-6.4 (focal lengths in full frame equivalent terms). The TZ90 offers the faster maximum aperture.

The HX99 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the TZ90 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 Sony Cyber-shot DSC-HX99 and Panasonic Lumix DC-TZ90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the HX99 and the TZ90 have been discontinued, but can regularly be found used on ebay. The TZ90 was replaced by the Panasonic TZ95, while the HX99 does not have a direct successor. Further information on the features and operation of the HX99 and TZ90 can be found, respectively, in the Sony HX99 Manual (free pdf) or the online Panasonic TZ90 Manual.

Review summary

So what is the bottom line? Is the Sony HX99 better than the Panasonic TZ90 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Cyber-shot DSC-HX99:

• More compact: Is smaller (102x58mm vs 112x67mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 80g or 25 percent) and hence easier to carry around.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Is somewhat more recent (announced 1 year and 4 months after the TZ90).

Arguments in favor of the Panasonic Lumix DC-TZ90:

• More detail: Has more megapixels (20.2 vs 18MP), which boosts linear resolution by 6%.
• More detailed viewfinder: Has higher resolution electronic viewfinder (1166k vs 638k dots).
• More detailed LCD: Has a higher resolution rear screen (1040k 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/3.3 vs f/3.5).
• More heavily discounted: Has been on the market for longer (launched in April 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the TZ90 comes out slightly ahead of the HX99 (6 : 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 Panasonic TZ90 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing 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 TZ90 in practical situations. 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.

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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
