Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS 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

The side-by-side display below illustrates the physical size and weight of the Canon SX420 and the Leica C-LUX. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The SX420 can be obtained in two different colors (black, red), 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 Leica C-LUX is notably larger (6 percent) than the Canon SX420. Moreover, the C-LUX is markedly heavier (5 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the C-LUX are weather-sealed.

The power pack in the C-LUX can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 SX420 was launched at a markedly lower price (by 71 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.

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon SX420 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 SX420 has a native 4:3 aspect ratio, while the one in the C-LUX offers a 3:2 aspect.

With 20MP, the C-LUX offers a higher resolution than the SX420 (19.9MP), but the C-LUX nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.19μm for the SX420) due to its larger sensor. Moreover, the C-LUX is a much more recent model (by 2 years and 5 months) than the SX420, and its sensor will 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 SX420 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. 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 SX420 is build around a CCD 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the C-LUX provides a better video resolution than the SX420. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the C-LUX has an electronic viewfinder (2330k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX420 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX420 and Leica C-LUX along with similar information for a selection of comparators.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The C-LUX has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 C-LUX 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 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 SX420 and the C-LUX have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 optic and the C-LUX offers a 24-360mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Canon and Leica provide the same view at the wide-angle end, but the Leica has less tele-photo reach at the long end. The C-LUX offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX420 and the C-LUX write their files to SDXC cards. The C-LUX supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX420 cannot take advantage of Ultra High Speed SD cards.

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 Canon PowerShot SX420 IS and Leica C-LUX and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX420 and the C-LUX have been discontinued, but can regularly be found used on ebay. The SX420 was replaced by the Canon SX430, while the C-LUX does not have a direct successor. Further information on the features and operation of the SX420 and C-LUX can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Leica C-LUX Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon SX420 or the Leica C-LUX – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon PowerShot SX420 IS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in January 2016).

Advantages of 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.
• Better video: Provides higher definition movie capture (4K/30p vs 720/25p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1240k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (10 vs 0.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.3 vs f/3.5).
• Longer lasting: Gets more shots (370 versus 195) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 2 years and 5 months of technical progress since the SX420 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the C-LUX is the clear winner of the contest (18 : 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 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 Canon SX420 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX420 or the C-LUX. 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 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
