Going beyond this snapshot of core features and characteristics, what are the differences between the Leica X1 and the Nikon D1X? 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 D1X 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 D1X 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 D1X is considerably larger (223 percent) than the Leica X1. It is noteworthy in this context that the D1X 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 D1X 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 D1X 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 D1X can take 1200 images on a single charge of its Nikon EN-4 power pack. As can be seen in the images above, the D1X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X1 was launched at a lower price than the D1X, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the X1 offers a higher resolution of 12.2 megapixels, compared with 5.9 MP of the D1X. This megapixels advantage translates into a 42 percent gain in linear resolution. On the other hand, these sensor specs imply that the X1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.51μm versus 7.92μm for the D1X). In this context, it should be noted, however, that the X1 is much more recent (by 8 years and 7 months) than the D1X, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Leica X1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X1 for good quality output (200 dots per inch) amounts to 21.4 x 14.3 inches or 54.3 x 36.3 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 29 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.2 cm. The corresponding values for the Nikon D1X are 15 x 9.8 inches or 38.2 x 24.9 cm for good quality, 12 x 7.8 inches or 30.6 x 19.9 cm for very good quality, and 10 x 6.5 inches or 25.5 x 16.6 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 D1X are ISO 125 to ISO 800, with the possibility to increase the ISO range to 125-3200.

In terms of underlying technology, the X1 is build around a CMOS sensor, while the D1X 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D1X 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 table below summarizes some of the other core capabilities of the Leica X1 and Nikon D1X in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The X1 has one, while the D1X 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 X1 writes its imaging data to SDHC cards, while the D1X uses Compact Flash cards.

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 D1X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D1X (unlike the X1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X1 and the D1X have been discontinued, but can regularly be found used on ebay. The D1X was replaced by the Nikon D2X, while the X1 was followed by the Leica X2. Further information on the features and operation of the X1 and D1X can be found, respectively, in the Leica X1 Manual (free pdf) or the online Nikon D1X Manual.

Review summary

So what conclusions can be drawn? Is the Leica X1 better than the Nikon D1X or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Leica X1:

• More detail: Offers more megapixels (12.2 vs 5.9MP) with a 43% higher linear resolution.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
• Ready to shoot: Comes with a built-in lens, while the D1X requires a separate lens.
• More compact: Is smaller (124x60mm vs 157x153mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D1X).
• 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 modern: Reflects 8 years and 7 months of technical progress since the D1X launch.

Reasons to prefer the Nikon D1X:

• 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.
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/2000s) to freeze action.
• 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 (1200 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.
• More heavily discounted: Has been around for much longer (launched in February 2001).

If the number of relative strengths (bullet points above) is taken as a guide, the X1 comes out slightly ahead of the D1X (10 : 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 X1 and the Nikon D1X 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 D1X 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
