Canon SL1 vs Nikon D2X

The Canon EOS Rebel SL1 (called Canon 100D in some regions) and the Nikon D2X are two digital cameras that were revealed to the public, respectively, in March 2013 and September 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 17.9 megapixels, whereas the Nikon provides 12.2 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 SL1 and the Nikon D2X? 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 Canon SL1 and the Nikon D2X 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 size dimensions are rounded to the nearest millimeter.

The SL1 can be obtained in two different colors (black, white), while the D2X 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 D2X is considerably larger (123 percent) than the Canon SL1. Moreover, the D2X is substantially heavier (208 percent) than the SL1. It is noteworthy in this context that the D2X is splash and dust-proof, while the SL1 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 (SL1) and the Nikon Lens Catalog (D2X).

Concerning battery life, the SL1 gets 380 shots out of its Canon LP-E12 battery, while the D2X can take 3800 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D2X 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 SL1, there are third party battery grips available as optional accessories (see here on ebay).

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 SL1 was launched at a markedly lower price (by 89 percent) than the D2X, 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 size of the imaging sensor is a crucial determinant 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 tend to be more expensive and 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 D2X is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (SL1) 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 SL1 offers a higher resolution of 17.9 megapixels, compared with 12.2 MP of the Nikon D2X. 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 5.52μm for the D2X). However, it should be noted that the SL1 is much more recent (by 8 years and 6 months) than the D2X, 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 SL1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL1 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 D2X are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The SL1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel SL1 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon D2X are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the SL1 has a notably higher overall DXO score than the D2X (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits lower color depth, 0.4 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The SL1 indeed provides movie recording capabilities, while the D2X does not. The highest resolution format that the SL1 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SL1 and the D2X 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 D2X offers a wider field of view (100%) than the one in the SL1 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D2X has a higher magnification (0.57x vs 0.54x), 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 Canon SL1 and Nikon D2X 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 SL1 has one, while the D2X does not. While the built-in flash of the SL1 is not very powerful, it can at times be useful as a fill-in light.

The SL1 writes its imaging data to SDXC cards, while the D2X 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 SL1 and Nikon D2X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2X (unlike the SL1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the SL1 and the D2X have been discontinued, but can regularly be found used on ebay. The D2X was replaced by the Nikon D2Xs, while the SL1 was followed by the Canon SL2. Further information on the features and operation of the SL1 and D2X can be found, respectively, in the Canon SL1 Manual (free pdf) or the online Nikon D2X Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon SL1 and the Nikon D2X? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS Rebel SL1:

• More detail: Offers more megapixels (17.9 vs 12.2MP) with a 21% higher linear resolution.
• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 235k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More compact: Is smaller (117x91mm vs 158x150mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 845g or 67 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 (89 percent cheaper at launch).
• More modern: Reflects 8 years and 6 months of technical progress since the D2X launch.

Reasons to prefer the Nikon D2X:

• 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 (0.57x 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.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3800 versus 380) 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 September 2004).

If the count of individual advantages (bullet points above) is taken as a guide, the SL1 is the clear winner of the match-up (13 : 9 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 Canon SL1 and the Nikon D2X 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 SL1 or the D2X 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 where reviews by experts come in. 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
