Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 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 side-by-side display below illustrates the physical size and weight of the Leica D-LUX 5 and the Leica S1. 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 S1 is considerably larger (915 percent) than the Leica D-LUX 5. In this context, it is worth noting that neither the D-LUX 5 nor the S1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 5 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 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, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D-LUX 5 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 size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 5 features a 1/1.7-inch sensor and the Leica S1 a medium format sensor. The sensor area in the S1 is 2717 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 0.85. The sensor in the D-LUX 5 has a native 4:3 aspect ratio, while the one in the S1 offers a 1:1 aspect. The D-LUX 5 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 5 (10MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 7.01μm versus 2.14μm for the D-LUX 5) due to its larger sensor. However, the D-LUX 5 is a much more recent model (by 14 years) 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 the S1 has no anti-alias filter installed, so that it can capture all the detail its 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 5 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Leica D-LUX 5 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Leica S1 Pro are ISO 50 to ISO 1600 (no boost).

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) sensors. 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D-LUX 5 indeed provides movie recording capabilities, while the S1 does not. The highest resolution format that the D-LUX 5 can use is 720/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the S1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the D-LUX 5 relies on live view and the rear LCD for framing. That said, the D-LUX 5 can be equipped with an optional viewfinder – the EVF1. The adjacent table lists some of the other core features of the Leica D-LUX 5 and Leica S1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D-LUX 5 has one, while the S1 does not. While the built-in flash of the D-LUX 5 is not very powerful, it can at times be useful as a fill-in light.

The D-LUX 5 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 5 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 5 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 5 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 5 was followed by the Leica D-LUX 6. 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 what conclusions can be drawn? Is the Leica D-LUX 5 better than the Leica S1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Leica D-LUX 5:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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 720/60p movies.
• Rear screen: Has a backside LCD (3.0") for image review and settings control.
• Faster burst: Shoots at higher frequency (2.5 vs 0.01 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the S1 requires a separate lens.
• More compact: Is smaller (110x65mm 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).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 14 years of technical progress since the S1 launch.

Arguments in favor of the Leica S1 Pro:

• More detail: Has more megapixels (26.4 vs 10MP), which boosts linear resolution by 59%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 5 is the clear winner of the match-up (13 : 9 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 5 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 5 or the S1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews 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.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
