Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-TZ90 and the Leica C-LUX? 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

An illustration of the physical size and weight of the Panasonic TZ90 and the Leica C-LUX is provided 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 size dimensions are rounded to the nearest millimeter.

The TZ90 can be obtained in two different colors (black, silver), while the C-LUX is also available in two color-versions, but different ones (gold, blue).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ90 and the Leica C-LUX are of equal size. However, the C-LUX is markedly heavier (6 percent) than the TZ90. In this context, it is worth noting that neither the TZ90 nor the C-LUX are weather-sealed.

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.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The TZ90 was launched at a markedly lower price (by 57 percent) than the C-LUX, 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 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 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic TZ90 features a 1/2.3-inch sensor and the Leica C-LUX an one-inch sensor. The sensor area in the C-LUX 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 TZ90 has a native 4:3 aspect ratio, while the one in the C-LUX offers a 3:2 aspect.

Despite having a smaller sensor, the Panasonic TZ90 offers a higher resolution of 20.2 megapixels, compared with 20 MP of the Leica C-LUX. 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 C-LUX). Moreover, it should be noted that the C-LUX is a somewhat more recent model (by 1 year and 1 month) than the TZ90, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Panasonic Lumix DC-TZ90 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 Leica C-LUX are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the TZ90 is build around a BSI-CMOS sensor, while the C-LUX uses a 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.

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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, 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 C-LUX offers a substantially higher resolution than the one in the TZ90 (2330k vs 1166k dots). The table below summarizes some of the other core capabilities of the Panasonic TZ90 and Leica C-LUX in connection with corresponding information for a sample of similar cameras.

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, 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).

The Leica C-LUX has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both the TZ90 and the C-LUX have zoom lenses built in. The TZ90 has a 24-720mm f/3.3-6.4 optic and the C-LUX offers a 24-360mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Panasonic and Leica provide the same view at the wide-angle end, but the Leica has less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the TZ90 and the C-LUX write their files to 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 Panasonic Lumix DC-TZ90 and Leica C-LUX and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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

Review summary

So how do things add up? Is there a clear favorite between the Panasonic TZ90 and the Leica C-LUX? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Panasonic Lumix DC-TZ90:

• 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.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in April 2017).

Reasons to prefer the Leica C-LUX:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2330k vs 1166k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.46x).
• More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the C-LUX is the clear winner of the contest (11 : 6 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 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 Panasonic TZ90 and the Leica C-LUX 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the TZ90 and the C-LUX 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 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 (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 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.
