Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX620 HS and the Leica CL (Typ 7323)? 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 Canon SX620 and the Leica CL is provided 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 SX620 can be obtained in three different colors (black, silver, red), while the CL 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 Leica CL is considerably larger (85 percent) than the Canon SX620. In this context, it is worth noting that neither the SX620 nor the CL are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 has a lens built in, whereas the CL is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the SX620 gets 295 shots out of its Canon NB-13L battery, while the CL can take 220 images on a single charge of its Leica BP-DC12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 SX620 was launched at a lower price than the CL, despite having a lens built in. 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 imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Leica CL an APS-C sensor. The sensor area in the CL is 1225 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX620 has a native 4:3 aspect ratio, while the one in the CL offers a 3:2 aspect.

With 24.1MP, the CL offers a higher resolution than the SX620 (20.2MP), but the CL nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 1.18μm for the SX620) due to its larger sensor. Moreover, the CL is a somewhat more recent model (by 1 year and 6 months) than the SX620, 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 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 Leica CL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the CL for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Canon SX620 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Leica CL (Typ 7323) are ISO 100 to ISO 50000 (no boost).

In terms of underlying technology, the SX620 is build around a BSI-CMOS sensor, while the CL 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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the CL provides a better video resolution than the SX620. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the CL has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX620 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX620, the Leica CL, and comparable cameras.

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 SX620 has one, while the CL does not. While the built-in flash of the SX620 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 CL 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 CL 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.

Concerning the storage of imaging data, both the SX620 and the CL write their files to SDXC cards. The CL supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the SX620 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 SX620 HS and Leica CL (Typ 7323) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the CL has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX620 does not feature such an accessory-socket.

Both the SX620 and the CL 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 Canon and Leica. Further information on the features and operation of the SX620 and CL can be found, respectively, in the Canon SX620 Manual (free pdf) or the online Leica CL Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon SX620 and the Leica CL? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX620 HS:

• Ready to shoot: Has a lens built-in, whereas the CL requires a separate lens.
• More compact: Is smaller (97x57mm vs 131x78mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the CL).
• Longer lasting: Can take more shots (295 versus 220) on a single battery charge.
• 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.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in May 2016).

Reasons to prefer the Leica CL (Typ 7323):

• More detail: Has more megapixels (24.1 vs 20.2MP), which boosts linear resolution by 12%.
• 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 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 2.5 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.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the CL is the clear winner of the contest (19 : 9 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 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 SX620 and the Leica CL place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 SX620 and the CL in practical situations. 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
