Canon 40D vs Leica D-LUX 7
The Canon EOS 40D and the Leica D-LUX 7 are two enthusiast cameras that were revealed to the public, respectively, in August 2007 and November 2018. The 40D is a DSLR, while the D-LUX 7 is a fixed lens compact. The cameras are based on an APS-C (40D) and a Four Thirds (D-LUX 7) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Leica provides 16.8 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 40D and the Leica D-LUX 7? 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.
The physical size and weight of the Canon 40D and the Leica D-LUX 7 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 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 D-LUX 7 is considerably smaller (52 percent) than the Canon 40D. In this context, it is worth noting that neither the 40D nor the D-LUX 7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 7 has a lens built in, whereas the 40D 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 40D and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the D-LUX 7 can take 300 images on a single charge of its BP-DC15 power pack. The power pack in the D-LUX 7 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D-LUX 7 was launched at a lower price than the 40D, 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.
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. 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 40D features an APS-C sensor and the Leica D-LUX 7 a Four Thirds sensor. The sensor area in the D-LUX 7 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 40D has a native 3:2 aspect ratio, while the one in the D-LUX 7 offers a 4:3 aspect. The D-LUX 7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
Despite having a smaller sensor, the D-LUX 7 offers a higher resolution of 16.8 megapixels, compared with 10.1 MP of the 40D. 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 3.66μm versus 5.73μm for the 40D). However, it should be noted that the D-LUX 7 is much more recent (by 11 years and 3 months) than the 40D, 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 D-LUX 7 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica D-LUX 7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D-LUX 7 for good quality output (200 dots per inch) amounts to 23.7 x 17.8 inches or 60.1 x 45.1 cm, for very good quality (250 dpi) 18.9 x 14.2 inches or 48.1 x 36.1 cm, and for excellent quality (300 dpi) 15.8 x 11.8 inches or 40.1 x 30.1 cm. The corresponding values for the Canon 40D 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 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Leica D-LUX 7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 D-LUX 7 indeed provides for movie recording, while the 40D does not. The highest resolution format that the D-LUX 7 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D-LUX 7 has an electronic viewfinder (2764k dots), while the 40D 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 D-LUX 7 offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D-LUX 7 has a higher magnification (0.70x vs 0.59x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 40D, the Leica D-LUX 7, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the D-LUX 7 does not. While the built-in flash of the 40D 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 D-LUX 7 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 D-LUX 7 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.
The 40D writes its imaging data to Compact Flash cards, while the D-LUX 7 uses SDXC cards.
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 EOS 40D and Leica D-LUX 7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D-LUX 7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 40D does not provide wifi capability.
Studio photographers will appreciate that the Canon 40D (unlike the D-LUX 7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The D-LUX 7 is a recent model that features in the current product line-up of Leica. In contrast, the 40D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.
So what conclusions can be drawn? Which of the two cameras – the Canon 40D or the Leica D-LUX 7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the D-LUX 7 is the clear winner of the contest (22 : 9 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.

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 40D or the D-LUX 7 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.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
