Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D1 and the Leica TL2? 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 Nikon D1 and the Leica TL2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The TL2 can be obtained in two different colors (black, silver), while the D1 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 Leica TL2 is considerably smaller (62 percent) than the Nikon D1. Moreover, the TL2 is substantially lighter (64 percent) than the D1. It is worth mentioning in this context that the D1 is splash and dust resistant, while the TL2 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the D1 gets .. shots out of its Nikon EN-4 battery, while the TL2 can take 250 images on a single charge of its Leica BP-DC13 power pack. As can be seen in the images above, the D1 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the TL2 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 TL2 was launched at a markedly lower price (by 65 percent) than the D1, which puts it into a different market segment. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24.1MP, the TL2 offers a higher resolution than the D1 (2.6MP), but the TL2 has smaller individual pixels (pixel pitch of 3.92μm versus 11.93μm for the D1). Yet, the TL2 is a much more recent model (by 18 years) than the D1, 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 TL2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica TL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TL2 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Nikon D1 are 10 x 6.6 inches or 25.4 x 16.7 cm for good quality, 8 x 5.2 inches or 20.3 x 13.3 cm for very good quality, and 6.7 x 4.4 inches or 16.9 x 11.1 cm for excellent quality prints.

The Nikon D1 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-6400. The corresponding ISO settings for the Leica TL2 are ISO 100 to ISO 50000 (no boost).

In terms of underlying technology, the D1 is build around a CCD sensor, while the TL2 uses a CMOS 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The TL2 indeed provides for movie recording, while the D1 does not. The highest resolution format that the TL2 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 D1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TL2 relies on live view and the rear LCD for framing. That said, the TL2 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Nikon D1 and Leica TL2 along with similar information for a selection of comparators.

One feature that is present on the D1, but is missing on the TL2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The D1 writes its imaging data to Compact Flash cards, while the TL2 uses SDXC 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 Nikon D1 and Leica TL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the TL2 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D1 does not provide wifi capability.

Studio photographers will appreciate that the Nikon D1 (unlike the TL2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D1 and the TL2 have been discontinued, but can regularly be found used on ebay. The D1 was replaced by the Nikon D1X, while the TL2 does not have a direct successor. Further information on the features and operation of the D1 and TL2 can be found, respectively, in the Nikon D1 Manual (free pdf) or the online Leica TL2 Manual.

Review summary

So what is the bottom line? Is the Nikon D1 better than the Leica TL2 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Nikon D1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/4000s) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in June 1999).

Arguments in favor of the Leica TL2:

• More detail: Has more megapixels (24.1 vs 2.6MP), which boosts linear resolution by 202%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• Larger screen: Has a bigger rear LCD (3.7" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 120k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (7 vs 4.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (134x69mm vs 157x153mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 701g or 64 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
• More modern: Reflects 18 years of technical progress since the D1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TL2 is the clear winner of the contest (15 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 Nikon D1 and the Leica TL2 place the cameras among the top in their class? Find out in the latest Best DSLR 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D1 or the TL2. 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 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
