Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX40 HS and the Leica V-LUX 4? 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 SX40 and the Leica V-LUX 4 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica V-LUX 4 is somewhat smaller (4 percent) than the Canon SX40. Moreover, the V-LUX 4 is slightly lighter (2 percent) than the SX40. In this context, it is worth noting that neither the SX40 nor the V-LUX 4 are weather-sealed.

Concerning battery life, the SX40 gets 380 shots out of its Canon NB-10L battery, while the V-LUX 4 can take 540 images on a single charge of its Leica BP-DC12 power pack.

The price is, of course, an important factor in any camera decision. 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 SX40 was launched at a markedly lower price (by 55 percent) than the V-LUX 4, 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12 megapixels. This similarity in sensor specs implies that both the SX40 and the V-LUX 4 have the same pixel density, as well as the same pixel size. It should, however, be noted that the V-LUX 4 is a somewhat more recent model (by 1 year) than the SX40, and its sensor might have benefitted from technological advances during this time. 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 Canon PowerShot SX40 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Leica V-LUX 4 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

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.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 V-LUX 4 provides a faster frame rate than the SX40. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/24p.

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 V-LUX 4 offers a substantially higher resolution than the one in the SX40 (1312k vs 202k dots). The following table reports on some other key feature differences and similarities of the Canon SX40, the Leica V-LUX 4, and comparable cameras.

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

Both the SX40 and the V-LUX 4 have zoom lenses built in. The SX40 has a 24-840mm f/2.7-5.8 optic and the V-LUX 4 offers a 25-600mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Leica. The SX40 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX40 and the V-LUX 4 write their files to SDXC cards. The V-LUX 4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX40 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 SX40 HS and Leica V-LUX 4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the V-LUX 4 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The SX40 does not feature such a mic input.

Both the SX40 and the V-LUX 4 have been discontinued, but can regularly be found used on ebay. The SX40 was replaced by the Canon SX50, while the V-LUX 4 was followed by the Leica V-LUX Typ 114. Further information on the features and operation of the SX40 and V-LUX 4 can be found, respectively, in the Canon SX40 Manual (free pdf) or the online Leica V-LUX 4 Manual.

Review summary

So what is the bottom line? Is the Canon SX40 better than the Leica V-LUX 4 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX40 HS:

• Better light gathering: Has a lens with a wider maximum aperture (f/2.7 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2011).

Reasons to prefer the Leica V-LUX 4:

• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (1312k vs 202k dots).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Faster burst: Shoots at higher frequency (12 vs 10.3 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (540 versus 380) out of a single battery charge.
• 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: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the V-LUX 4 is the clear winner of the contest (12 : 5 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 Canon SX40 and the Leica V-LUX 4 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX40 and the V-LUX 4 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 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
