Sony A7R III versus Leica D-LUX Typ 109
The Sony Alpha A7R III and the Leica D-LUX (Typ 109) are two digital cameras that were announced, respectively, in October 2017 and September 2014. The A7R III is a mirrorless interchangeable lens camera, while the D-LUX Typ 109 is a fixed lens compact. The cameras are based on a full frame (A7R III) and a Four Thirds sensor. The Sony has a resolution of 42.2 megapixel, whereas the Leica provides 12.7 MP.
The physical size and weight of the Sony A7R III and the Leica D-LUX Typ 109 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the A7R III – represents 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica D-LUX Typ 109 is considerably smaller (36 percent) than the Sony A7R III. It is worth mentioning in this context that the A7R III is splash and dust resistant, while the D-LUX Typ 109 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 Typ 109 has a lens build in, whereas the A7R III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the A7R III and their specifications in the Sony FE Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D-LUX Typ 109 was launched at a lower price than the A7R III, despite having a lens build 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 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. 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 Sony A7R III features a full frame sensor and the Leica D-LUX Typ 109 a Four Thirds sensor. The sensor area in the D-LUX Typ 109 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the A7R III has a native 3:2 aspect ratio, while the one in the D-LUX Typ 109 offers a 4:3 aspect.
With 42.2MP, the A7R III offers a higher resolution than the D-LUX Typ 109 (12.7MP), but the A7R III nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 4.21μm for the D-LUX Typ 109) due to its larger sensor. Moreover, the A7R III is a somewhat more recent model (by 3 years and 1 month) than the D-LUX Typ 109, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the A7R III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the D-LUX Typ 109, the A7R III has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the A7R III offers a substantially higher resolution than the one in the D-LUX Typ 109 (3686k vs 2764k dots). The table below summarizes some of the other core capabilities of the Sony A7R III and Leica D-LUX Typ 109 in connection with corresponding information for a sample of similar cameras.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R III is the clear winner of the match-up (14 : 7 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7R III or the D-LUX Typ 109. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 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.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored.
