Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX10 II 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 side-by-side display below illustrates the physical size and weight of the Sony RX10 II and the Panasonic TZ90. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The TZ90 can be obtained in two different colors (black, silver), while the RX10 II 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 considerably smaller (34 percent) than the Sony RX10 II. Moreover, the TZ90 is substantially lighter (60 percent) than the RX10 II. It is worth mentioning in this context that the RX10 II is splash and dust resistant, while the TZ90 does not feature any corresponding weather-sealing.

Concerning battery life, the RX10 II gets 400 shots out of its Sony NP-FW50 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 TZ90 was launched at a markedly lower price (by 65 percent) than the RX10 II, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Sony RX10 II features an one-inch sensor and the Panasonic TZ90 a 1/2.3-inch sensor. The sensor area in the TZ90 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the RX10 II has a native 3:2 aspect ratio, while the one in the TZ90 offers a 4:3 aspect.

Despite having a smaller sensor, the TZ90 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the RX10 II. 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 1.18μm versus 2.41μm for the RX10 II). However, it should be noted that the TZ90 is a somewhat more recent model (by 1 year and 10 months) than the RX10 II, 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 TZ90 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Sony Cyber-shot DSC-RX10 II has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The corresponding ISO settings for the Panasonic Lumix DC-TZ90 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

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.

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"). Of the two cameras under review, the RX10 II provides substantially higher image quality than the TZ90, with an overall score that is 34 points higher. This advantage is based on 3.9 bits higher color depth, 2 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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

One feature that is present on the RX10 II, but is missing on the TZ90 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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, both cameras under consideration feature an 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 RX10 II and the TZ90 have zoom lenses built in. The RX10 II has a 24-200mm f/2.8-2.8 optic and the TZ90 offers a 24-720mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Sony and Panasonic provide the same view at the wide-angle end, but the Panasonic has more tele-photo reach at the long end. The RX10 II offers the faster maximum aperture.

The RX10 II 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-RX10 II and Panasonic Lumix DC-TZ90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 II has a hotshoe, while the TZ90 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the RX10 II and the TZ90 have been discontinued, but can regularly be found used on ebay. The RX10 II was replaced by the Sony RX10 III, while the TZ90 was followed by the Panasonic TZ95. Further information on the features and operation of the RX10 II and TZ90 can be found, respectively, in the Sony RX10 II Manual (free pdf) or the online Panasonic TZ90 Manual.

Review summary

So how do things add up? Is the Sony RX10 II 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-RX10 II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores substantially higher (34 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (3.9 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.3 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1166k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.46x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.3).
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been on the market for longer (launched in June 2015).

Reasons to prefer the Panasonic Lumix DC-TZ90:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (112x67mm vs 129x88mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 491g or 60 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 10 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 II is the clear winner of the match-up (18 : 8 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 RX10 II and the Panasonic TZ90 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom 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 RX10 II or the TZ90. 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
