Going beyond this snapshot of core features and characteristics, what are the differences between the Leica X1 and the Nikon D4S? 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

An illustration of the physical size and weight of the Leica X1 and the Nikon D4S is provided 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 measures are rounded to the nearest millimeter.

The X1 can be obtained in two different colors (black, silver), while the D4S is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D4S is considerably larger (238 percent) than the Leica X1. It is noteworthy in this context that the D4S is splash and dust-proof, while the X1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X1 has a lens built in, whereas the D4S 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 D4S and their specifications in the Nikon Lens Catalog.

Concerning battery life, the X1 gets 260 shots out of its Leica BP-DC8 battery, while the D4S can take 3020 images on a single charge of its Nikon EN-EL18a power pack. As can be seen in the images above, the D4S has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X1 was launched at a lower price than the D4S, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica X1 features an APS-C sensor and the Nikon D4S a full frame sensor. The sensor area in the D4S is 132 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 16.2MP, the D4S offers a higher resolution than the X1 (12.2MP), but the D4S nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 5.51μm for the X1) due to its larger sensor. Moreover, the D4S is a much more recent model (by 4 years and 5 months) than the X1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D4S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D4S for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.8 cm. The corresponding values for the Leica X1 are 21.4 x 14.3 inches or 54.3 x 36.3 cm for good quality, 17.1 x 11.4 inches or 43.4 x 29 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.2 cm for excellent quality prints.

The Leica X1 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Nikon D4S are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-409600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) 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 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 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 D4S indeed provides for movie recording, while the X1 does not. The highest resolution format that the D4S can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D4S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Leica X1, the Nikon D4S, and comparable cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The X1 has one, while the D4S does not. While the built-in flash of the X1 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D4S 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 X1 writes its imaging data to SDHC cards, while the D4S uses Compact Flash or XQD cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X1 only has one slot.

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 X1 and Nikon D4S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D4S (unlike the X1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X1 and the D4S have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the D4S was followed by the Nikon D5. Further information on the features and operation of the X1 and D4S can be found, respectively, in the Leica X1 Manual (free pdf) or the online Nikon D4S Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica X1 and the Nikon D4S? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica X1:

• Ready to shoot: Comes with a built-in lens, while the D4S requires a separate lens.
• More compact: Is smaller (124x60mm vs 160x157mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D4S).
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been available for much longer (launched in September 2009).

Arguments in favor of the Nikon D4S:

• More detail: Has more megapixels (16.2 vs 12.2MP), which boosts linear resolution by 15%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3020 versus 260) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 4 years and 5 months of technical progress since the X1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D4S is the clear winner of the contest (20 : 7 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 X1 and the Nikon D4S place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the X1 or the D4S perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
