Nikon D1 vs Canon XTi

The Nikon D1 and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were officially introduced, respectively, in June 1999 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Nikon has a resolution of 2.6 megapixels, whereas the Canon provides 10.1 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D1 and the Canon EOS Rebel XTi? 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 Canon XTi are illustrated 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 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 Canon XTi is considerably smaller (56 percent) than the Nikon D1. Moreover, the XTi is substantially lighter (49 percent) than the D1. It is worth mentioning in this context that the D1 is splash and dust resistant, while the XTi 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D1) and the Canon EF Lens Catalog (XTi).

Concerning battery life, the D1 gets .. shots out of its Nikon EN-4 battery, while the XTi can take 370 images on a single charge of its Canon NB-2LH 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. In order to provide similar functionality for the XTi, Canon provides the BG-E3 vertical grip as an optional accessory (see here on ebay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. 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 XTi was launched at a markedly lower price (by 85 percent) than the D1, which puts it into a different market segment. 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. 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 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. 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, but their sensors differ slightly in size. The sensor area in the XTi is 11 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (D1) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the XTi offers a higher resolution of 10.1 megapixels, compared with 2.6 MP of the D1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.71μm versus 11.93μm for the D1). However, it should be noted that the XTi is much more recent (by 7 years and 2 months) than the D1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon XTi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XTi for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 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 Canon EOS Rebel XTi are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the D1 is build around a CCD sensor, while the XTi 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 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 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 variety of features. The D1 and the XTi are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the D1 offers a wider field of view (96%) than the one in the XTi (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D1 has a higher magnification (0.53x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D1 and Canon XTi in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D1, but is missing on the XTi 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.

Concerning the storage of imaging data, both the D1 and the XTi write their files to 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 Nikon D1 and Canon EOS Rebel XTi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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

Both the D1 and the XTi have been discontinued, but can regularly be found used on ebay. The D1 was replaced by the Nikon D1X, while the XTi was followed by the Canon Xsi. Further information on the features and operation of the D1 and XTi can be found, respectively, in the Nikon D1 Manual (free pdf) or the online Canon XTi Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D1 and the Canon XTi? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Nikon D1:

• More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.49x).
• 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.
• Faster burst: Shoots at higher frequency (4.5 vs 3 flaps/sec) to capture the decisive moment.
• 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).

Reasons to prefer the Canon EOS Rebel XTi:

• More detail: Has more megapixels (10.1 vs 2.6MP), which boosts linear resolution by 95%.
• Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
• More compact: Is smaller (127x84mm vs 157x153mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 544g or 49 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (85 percent cheaper at launch).
• More modern: Reflects 7 years and 2 months of technical progress since the D1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D1 comes out slightly ahead of the XTi (9 : 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 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 Nikon D1 and the Canon XTi place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D1 or the XTi 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 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
