Canon 550D vs Nikon D2H

The Canon EOS 550D (called Canon T2i in some regions) and the Nikon D2H are two digital cameras that were officially introduced, respectively, in February 2010 and July 2003. 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 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 550D and the Nikon D2H? 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 550D and the Nikon D2H 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D2H is considerably larger (87 percent) than the Canon 550D. Moreover, the D2H is substantially heavier (102 percent) than the 550D. It is noteworthy in this context that the D2H is splash and dust-proof, while the 550D 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 (550D) and the Nikon Lens Catalog (D2H).

Concerning battery life, the 550D gets 440 shots out of its Canon LP-E8 battery, while the D2H can take 2900 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D2H 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 550D, 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.

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 550D was launched at a markedly lower price (by 80 percent) than the D2H, 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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 D2H is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (550D) 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 550D offers a higher resolution of 17.9 megapixels, compared with 4 MP of the Nikon D2H. 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 9.50μm for the D2H). However, it should be noted that the 550D is much more recent (by 6 years and 6 months) than the D2H, 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 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D 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 D2H are 12.3 x 8.2 inches or 31.3 x 20.7 cm for good quality, 9.9 x 6.5 inches or 25 x 16.6 cm for very good quality, and 8.2 x 5.4 inches or 20.9 x 13.8 cm for excellent quality prints.

The Canon EOS 550D 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 D2H are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-6400.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 550D provides substantially higher image quality than the D2H, with an overall score that is 26 points higher. This advantage is based on 3.2 bits higher color depth, 1.5 EV in additional dynamic range, and 1.2 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 are not only capable of taking still images, but also of capturing video footage. The 550D indeed provides movie recording capabilities, while the D2H does not. The highest resolution format that the 550D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 550D and the D2H 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 D2H offers a wider field of view (100%) than the one in the 550D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D2H 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 adjacent table lists some of the other core features of the Canon 550D and Nikon D2H along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 550D has one, while the D2H does not. While the built-in flash of the 550D is not very powerful, it can at times be useful as a fill-in light.

The 550D writes its imaging data to SDXC cards, while the D2H 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 550D and Nikon D2H and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2H (unlike the 550D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 550D and the D2H have been discontinued, but can regularly be found used on ebay. The D2H was replaced by the Nikon D2Hs, while the 550D was followed by the Canon 600D. Further information on the features and operation of the 550D and D2H can be found, respectively, in the Canon 550D Manual (free pdf) or the online Nikon D2H Manual.

Review summary

So what is the bottom line? Is the Canon 550D better than the Nikon D2H or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS 550D:

• More detail: Offers more megapixels (17.9 vs 4MP) with a 111% higher linear resolution.
• Better image quality: Scores substantially higher (26 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (3.2 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 211k dots).
• More compact: Is smaller (129x98mm vs 158x150mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 540g or 50 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 (80 percent cheaper at launch).
• More modern: Reflects 6 years and 6 months of technical progress since the D2H launch.

Advantages of the Nikon D2H:

• 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.
• Faster burst: Shoots at higher frequency (8 vs 3.7 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (2900 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 July 2003).

If the number of relative strengths (bullet points above) is taken as a guide, the 550D emerges as the winner of the contest (13 : 10 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 550D and the Nikon D2H 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 550D or the D2H 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 expert reviews 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
