Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 7 and the Sony Alpha A7R? 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.
An illustration of the physical size and weight of the Leica D-LUX 7 and the Sony A7R 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 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 Sony A7R is considerably larger (57 percent) than the Leica D-LUX 7. It is noteworthy in this context that the A7R is splash and dust-proof, while the D-LUX 7 does not feature any corresponding weather-sealing.
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 A7R 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 A7R and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the D-LUX 7 gets 300 shots out of its BP-DC15 battery, while the A7R can take 340 images on a single charge of its NP-FW50 power pack. The battery packs of both cameras can be charged via USB, 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.

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 A7R, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Leica D-LUX 7 features a Four Thirds sensor and the Sony A7R a full frame sensor. The sensor area in the A7R is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the D-LUX 7 has a native 4:3 aspect ratio, while the one in the A7R offers a 3:2 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.
With 36.2MP, the A7R offers a higher resolution than the D-LUX 7 (16.8MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.66μm for the D-LUX 7) due to its larger sensor. However, the D-LUX 7 is a much more recent model (by 5 years and 1 month) than the A7R, 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 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 Sony A7R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Leica D-LUX 7 are 23.7 x 17.8 inches or 60.1 x 45.1 cm for good quality, 18.9 x 14.2 inches or 48.1 x 36.1 cm for very good quality, and 15.8 x 11.8 inches or 40.1 x 30.1 cm for excellent quality prints.
The Leica D-LUX 7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha A7R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D-LUX 7 provides a higher video resolution than the A7R. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the D-LUX 7 offers a higher resolution than the one in the A7R (2764k vs 2400k dots). The following table reports on some other key feature differences and similarities of the Leica D-LUX 7, the Sony A7R, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The D-LUX 7 has a touchscreen, while the A7R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 D-LUX 7 writes its imaging data to SDXC cards, while the A7R uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Leica D-LUX 7 and Sony Alpha A7R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The D-LUX 7 does not feature such a mic input.
The D-LUX 7 is a recent model that features in the current product line-up of Leica. In contrast, the A7R has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7R was succeeded by the Sony A7R II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Sony websites.
So what is the bottom line? Is there a clear favorite between the Leica D-LUX 7 and the Sony A7R? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the D-LUX 7 is the clear winner of the match-up (15 : 11 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.
How about other alternatives? Do the specifications of the Leica D-LUX 7 and the Sony A7R place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the D-LUX 7 or the A7R 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
