Canon T2i vs Nikon D3X
The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Nikon D3X are two digital cameras that were revealed to the public, respectively, in February 2010 and December 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T2i) and a full frame (D3X) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Nikon provides 24.4 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 Canon EOS Rebel T2i and the Nikon D3X? 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.
The side-by-side display below illustrates the physical size and weight of the Canon T2i and the Nikon D3X. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3X is considerably larger (99 percent) than the Canon T2i. Moreover, the D3X is substantially heavier (138 percent) than the T2i. It is noteworthy in this context that the D3X is splash and dust-proof, while the T2i 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T2i) and the Nikon Lens Catalog (D3X).
Concerning battery life, the T2i gets 440 shots out of its LP-E8 battery, while the D3X can take 4400 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, the D3X 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 T2i, Canon provides the BG-E8 vertical grip as an optional accessory (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

The price is, of course, an important factor in any camera decision. 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 T2i was launched at a markedly lower price (by 91 percent) than the D3X, 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.
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.
Of the two cameras under consideration, the Canon T2i features an APS-C sensor and the Nikon D3X a full frame sensor. The sensor area in the D3X is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24.4MP, the D3X offers a higher resolution than the T2i (17.9MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.31μm for the T2i) due to its larger sensor. However, the T2i is a somewhat more recent model (by 1 year and 2 months) than the D3X, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon D3X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3X for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Canon T2i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS Rebel T2i 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 D3X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-6400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the D3X offers substantially better image quality than the T2i (overall score 22 points higher). The advantage is based on 2.6 bits higher color depth, 2.2 EV in additional dynamic range, and 1.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The T2i indeed provides movie recording capabilities, while the D3X does not. The highest resolution format that the T2i can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The T2i and the D3X 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 D3X offers a wider field of view (100%) than the one in the T2i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D3X has a higher magnification (0.70x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon T2i and Nikon D3X along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T2i has one, while the D3X does not. While the built-in flash of the T2i is not very powerful, it can at times be useful as a fill-in light.
The Nikon D3X 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 T2i writes its imaging data to SDXC cards, while the D3X uses Compact Flash cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the T2i only has one slot.
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 T2i and Nikon D3X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D3X (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the T2i and the D3X have been discontinued, but can regularly be found used on eBay. The T2i was replaced by the Canon T3i, while the D3X does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what is the bottom line? Is the Canon T2i better than the Nikon D3X or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS Rebel T2i:
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- More compact: Is smaller (129x98mm vs 160x157mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 730g or 58 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 (91 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 2 months after the D3X).
Arguments in favor of the Nikon D3X:
- More detail: Has more megapixels (24.4 vs 17.9MP), which boosts linear resolution by 17%.
- Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.6 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.2 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.54x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 3.7 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Gets more shots (4400 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.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been on the market for longer (launched in December 2008).
If the count of relative strengths (bullet points above) is taken as a measure, the D3X is the clear winner of the contest (17 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 Canon T2i and the Nikon D3X 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 says little about, for example, the shooting experience and imaging performance of the T2i and the D3X in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews 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.

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
