Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 7 and the Leica S1 Pro? 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 Leica D-LUX 7 and the Leica S1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 S1 is considerably larger (856 percent) than the Leica D-LUX 7. In this context, it is worth noting that neither the D-LUX 7 nor the S1 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 S1 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 S1 and their specifications in the Leica R Lens Catalog.

The power pack in the D-LUX 7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. 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 S1, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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 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.

Of the two cameras under consideration, the Leica D-LUX 7 features a Four Thirds sensor and the Leica S1 a medium format sensor. The sensor area in the S1 is 601 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.2 and 0.85. The sensor in the D-LUX 7 has a native 4:3 aspect ratio, while the one in the S1 offers a 1:1 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 26.4MP, the S1 offers a higher resolution than the D-LUX 7 (16.8MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 7.01μm versus 3.32μm for the D-LUX 7) due to its larger sensor. However, the D-LUX 7 is a much more recent model (by 22 years and 2 months) than the S1, 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 Leica S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1 for good quality output (200 dots per inch) amounts to 25.7 x 25.7 inches or 65.3 x 65.3 cm, for very good quality (250 dpi) 20.6 x 20.6 inches or 52.2 x 52.2 cm, and for excellent quality (300 dpi) 17.1 x 17.1 inches or 43.5 x 43.5 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 Leica S1 Pro are ISO 50 to ISO 1600 (no boost).

In terms of underlying technology, the D-LUX 7 is build around a CMOS sensor, while the S1 uses a CCD 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.

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 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 can also record movies. The D-LUX 7 indeed provides movie recording capabilities, while the S1 does not. The highest resolution format that the D-LUX 7 can use is 4K/30p.

Feature comparison

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 S1 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 adjacent table lists some of the other core features of the Leica D-LUX 7 and Leica S1 along with similar information for a selection of comparators.

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

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 S1 uses external storage.

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 Leica D-LUX 7 and Leica S1 Pro 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 has a hotshoe, while the S1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the D-LUX 7 and the S1 have been discontinued, but can regularly be found used on ebay. The S1 was replaced by the Leica S2, while the D-LUX 7 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica website.

Review summary

So how do things add up? Is there a clear favorite between the Leica D-LUX 7 and the Leica S1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Leica D-LUX 7:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Broader imaging potential: Can record not only still images but also 4K/30p movies.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Rear screen: Has a backside LCD (3.0") for image review and settings control.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (11 vs 0.01 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has a lens built-in, whereas the S1 requires a separate lens.
• More compact: Is smaller (115x66mm vs 339x214mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the S1).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 22 years and 2 months of technical progress since the S1 launch.

Advantages of the Leica S1 Pro:

• More detail: Has more megapixels (26.4 vs 16.8MP), which boosts linear resolution by 23%.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More heavily discounted: Has been around for much longer (launched in August 1996).

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 (18 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 Leica S1 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 S1 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 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
