Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS and the Leica M (Typ 240)? 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 Canon SX420 and the Leica M Typ 240 are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.

The SX420 can be obtained in two different colors (black, red), while the M Typ 240 is also available in two color-versions, but different ones (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M Typ 240 is considerably larger (55 percent) than the Canon SX420. It is noteworthy in this context that the M Typ 240 is splash and dust-proof, while the SX420 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the M Typ 240 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the M Typ 240 and their specifications in the Leica M Lens Catalog.

Concerning battery life, the SX420 gets 195 shots out of its Canon NB-11LH battery, while the M Typ 240 can take 500 images on a single charge of its Leica BP-SCL2 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX420 was launched at a lower price than the M Typ 240, despite having a lens built in. 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. 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 M Typ 240 a full frame sensor. The sensor area in the M Typ 240 is 2957 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the M Typ 240 offers a 3:2 aspect.

With 23.7MP, the M Typ 240 offers a higher resolution than the SX420 (19.9MP), but the M Typ 240 nevertheless has larger individual pixels (pixel pitch of 6.01μm versus 1.19μm for the SX420) due to its larger sensor. However, the SX420 is a much more recent model (by 3 years and 3 months) than the M Typ 240, and its sensor will have benefitted from technological advances during this time that 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 resolution advantage of the Leica M Typ 240 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M Typ 240 for good quality output (200 dots per inch) amounts to 29.8 x 19.9 inches or 75.6 x 50.5 cm, for very good quality (250 dpi) 23.8 x 15.9 inches or 60.5 x 40.4 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.7 cm. The corresponding values for the Canon SX420 are 25.8 x 19.3 inches or 65.4 x 49.1 cm for good quality, 20.6 x 15.5 inches or 52.3 x 39.3 cm for very good quality, and 17.2 x 12.9 inches or 43.6 x 32.7 cm for excellent quality prints.

The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Leica M (Typ 240) are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the SX420 is build around a CCD sensor, while the M Typ 240 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 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, but the M Typ 240 provides a better video resolution than the SX420. It can shoot movie footage at 1080/25p, 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 M Typ 240 has an optical viewfinder, which can be very useful 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 M Typ 240 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The SX420 has one, while the M Typ 240 does not. While the built-in flash of the SX420 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the SX420 and the M Typ 240 write their files to SDXC cards. The M Typ 240 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 M (Typ 240) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX420 offers wifi support, while the M Typ 240 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the SX420 and the M Typ 240 have been discontinued, but can regularly be found used on ebay. The M Typ 240 was replaced by the Leica M Typ 262, while the SX420 was followed by the Canon SX430. Further information on the features and operation of the SX420 and M Typ 240 can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Leica M Typ 240 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX420 better than the Leica M Typ 240 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX420 IS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Ready to shoot: Has a lens built-in, whereas the M Typ 240 requires a separate lens.
• More compact: Is smaller (104x69mm vs 139x80mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the M Typ 240).
• 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 file upload: Has wifi built in for automatic backup or image transfer to the web.
• 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 modern: Reflects 3 years and 3 months of technical progress since the M Typ 240 launch.

Arguments in favor of the Leica M (Typ 240):

• More detail: Has more megapixels (23.7 vs 19.9MP), which boosts linear resolution by 11%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher definition movie capture (1080/25p vs 720/25p).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• Faster burst: Shoots at higher frequency (3 vs 0.5 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with different optics.
• Longer lasting: Gets more shots (500 versus 195) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• 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-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the M Typ 240 is the clear winner of the contest (17 : 10 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the SX420 or the M Typ 240 perform in practice. 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 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.

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.
