Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel T3i 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

The physical size and weight of the Canon T3i and the Nikon D1X 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 width, height and depth 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 Nikon D1X is considerably larger (81 percent) than the Canon T3i. Moreover, the D1X is substantially heavier (93 percent) than the T3i. It is noteworthy in this context that the D1X is splash and dust-proof, while the T3i 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 Canon EF Lens Catalog (T3i) and the Nikon Lens Catalog (D1X).

Concerning battery life, the T3i gets 440 shots out of its Canon LP-E8 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. In order to provide similar functionality for the T3i, Canon provides the BG-E8 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 T3i was launched at a markedly lower price (by 90 percent) than the D1X, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D1X is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T3i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon T3i offers a higher resolution of 17.9 megapixels, compared with 5.9 MP of the Nikon D1X. 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 4.31μm versus 7.92μm for the D1X). However, it should be noted that the T3i is much more recent (by 10 years) than the D1X, 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 T3i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 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 Canon EOS Rebel T3i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. 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 T3i 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.

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 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 can also record movies. The T3i indeed provides movie recording capabilities, while the D1X does not. The highest resolution format that the T3i can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The T3i and the D1X 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 viewfinders of both cameras offer the same magnification (0.53x), but the one in the D1X has a wider field of view (96%) than the finder in the T3i (95%), so that a larger proportion of the captured image is visible. The following table reports on some other key feature differences and similarities of the Canon T3i, the Nikon D1X, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The T3i has one, while the D1X does not. While the built-in flash of the T3i is not very powerful, it can at times be useful as a fill-in light.

The T3i writes its imaging data to SDXC 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 Canon EOS Rebel T3i 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 T3i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the T3i and the D1X have been discontinued, but can regularly be found used on ebay. The D1X was replaced by the Nikon D2X, while the T3i was followed by the Canon T4i. Further information on the features and operation of the T3i and D1X can be found, respectively, in the Canon T3i Manual (free pdf) or the online Nikon D1X Manual.

Review summary

So how do things add up? Is the Canon T3i better than the Nikon D1X or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS Rebel T3i:

• More detail: Offers more megapixels (17.9 vs 5.9MP) with a 74% higher linear resolution.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 120k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (133x100mm vs 157x153mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 530g or 48 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
• More modern: Reflects 10 years of technical progress since the D1X launch.

Reasons to prefer the Nikon D1X:

• More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
• Easier setting verification: Features a control panel on top to check 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.
• Longer lasting: Gets more shots (1200 versus 440) 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 count of relative strengths (bullet points above) is taken as a measure, the T3i emerges as the winner of the contest (12 : 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 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 Canon T3i and the Nikon D1X 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T3i or the D1X. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
