Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 400D 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

An illustration of the physical size and weight of the Canon 400D and the Leica V-LUX 4 is provided 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 size dimensions 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 larger (2 percent) than the Canon 400D. In this context, it is worth noting that neither the 400D nor the V-LUX 4 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the V-LUX 4 has a lens built in, whereas the 400D 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 400D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 400D gets 370 shots out of its Canon NB-2LH battery, while the V-LUX 4 can take 540 images on a single charge of its Leica BP-DC12 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 400D features an APS-C sensor and the Leica V-LUX 4 a 1/2.3-inch sensor. The sensor area in the V-LUX 4 is 91 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the 400D has a native 3:2 aspect ratio, while the one in the V-LUX 4 offers a 4:3 aspect.

Despite having a smaller sensor, the V-LUX 4 offers a higher resolution of 12 megapixels, compared with 10.1 MP of the 400D. 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 1.53μm versus 5.71μm for the 400D). However, it should be noted that the V-LUX 4 is much more recent (by 6 years) than the 400D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the V-LUX 4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica V-LUX 4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the V-LUX 4 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Canon 400D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. 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.

In terms of underlying technology, the 400D is build around a CMOS sensor, while the V-LUX 4 uses a BSI-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 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 V-LUX 4 indeed provides for movie recording, while the 400D does not. The highest resolution format that the V-LUX 4 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the V-LUX 4 has an electronic viewfinder (1312k dots), while the 400D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the V-LUX 4 offers a wider field of view (100%) than the one in the 400D (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 400D has a higher magnification (0.49x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 400D and Leica V-LUX 4 in connection with corresponding information for a sample of similar cameras.

Both the 400D and the V-LUX 4 have been discontinued, but can regularly be found used on ebay. The 400D was replaced by the Canon 450D, while the V-LUX 4 was followed by the Leica V-LUX Typ 114. Further information on the features and operation of the 400D and V-LUX 4 can be found, respectively, in the Canon 400D Manual (free pdf) or the online Leica V-LUX 4 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 400D and the Leica V-LUX 4? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 400D:

• 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.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.49x vs 0.46x).
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• More heavily discounted: Has been available for much longer (launched in August 2006).

Reasons to prefer the Leica V-LUX 4:

• More detail: Has more megapixels (12 vs 10.1MP), which boosts linear resolution by 7%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• More framing info: Has an electronic viewfinder that displays shooting data.

• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (12 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the 400D requires a separate lens.
• Longer lasting: Gets more shots (540 versus 370) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 6 years of technical progress since the 400D launch.

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 (15 : 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 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 400D and the Leica V-LUX 4 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings 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 remains incomplete and does no justice, for example, to the way the 400D or the V-LUX 4 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 where reviews by experts come in. 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
