Canon 5D vs T2i

The Canon EOS 5D and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were announced, respectively, in August 2005 and February 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D) and an APS-C (T2i) sensor. The 5D has a resolution of 12.7 megapixels, whereas the T2i provides 17.9 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 5D and the Canon EOS Rebel T2i? 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 5D and the Canon T2i 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 T2i is notably smaller (26 percent) than the Canon 5D. Moreover, the T2i is substantially lighter (41 percent) than the 5D. It is worth mentioning in this context that the 5D is splash and dust resistant, 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 (as in the 5D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T2i). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 5D gets 400 shots out of its Canon BP-511A battery, while the T2i can take 440 images on a single charge of its Canon LP-E8 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T2i was launched at a markedly lower price (by 79 percent) than the 5D, 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 5D features a full frame sensor and the Canon T2i an APS-C sensor. The sensor area in the T2i is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the T2i uses a more advanced image processing engine (DIGIC 4) than the 5D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the T2i offers a higher resolution of 17.9 megapixels, compared with 12.7 MP of the 5D. 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 8.25μm for the 5D). However, it should be noted that the T2i is much more recent (by 4 years and 5 months) than the 5D, 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 T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i 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 Canon 5D are 21.8 x 14.6 inches or 55.5 x 37 cm for good quality, 17.5 x 11.6 inches or 44.4 x 29.6 cm for very good quality, and 14.6 x 9.7 inches or 37 x 24.7 cm for excellent quality prints.

The Canon EOS 5D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Canon EOS Rebel T2i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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.

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. Of the two cameras under review, the 5D has a notably higher overall DXO score than the T2i (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.4 EV of lower dynamic range, and 0.8 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 for movie recording, while the 5D does not. The highest resolution format that the T2i can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 5D and the T2i 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 5D offers a wider field of view (96%) 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 5D has a higher magnification (0.71x 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 5D and Canon T2i along with similar information for a selection of comparators.

One feature that is present on the 5D, but is missing on the T2i 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.

The 5D writes its imaging data to Compact Flash cards, while the T2i uses SDXC 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 5D and Canon EOS Rebel T2i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 5D (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 5D and the T2i have been discontinued, but can regularly be found used on ebay. The 5D was replaced by the Canon 5D Mark II, while the T2i was followed by the Canon T3i. Further information on the features and operation of the 5D and T2i can be found, respectively, in the Canon 5D Manual (free pdf) or the online Canon T2i Manual.

Review summary

So what is the bottom line? Is the Canon 5D better than the Canon T2i or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 5D:

• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
• 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 (0.71x vs 0.54x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• 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 August 2005).

Arguments in favor of the Canon EOS Rebel T2i:

• More detail: Has more megapixels (17.9 vs 12.7MP), which boosts linear resolution by 19%.
• Better jpgs: Has a more modern image processing engine (DIGIC 4 vs DIGIC 2).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• 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 230k dots).
• Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (129x98mm vs 152x113mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 365g or 41 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 (79 percent cheaper at launch).
• More modern: Reflects 4 years and 5 months of technical progress since the 5D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T2i emerges as the winner of the match-up (11 : 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 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 5D and the Canon T2i 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 says little about, for example, the shooting experience and imaging performance of the 5D and the T2i in practical situations. 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.

The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
