Canon 5D Mark II vs T2i

The Canon EOS 5D Mark II and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were announced, respectively, in September 2008 and February 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D Mark II) and an APS-C (T2i) sensor. The 5D Mark II has a resolution of 21 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 Mark II 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

An illustration of the physical size and weight of the Canon 5D Mark II and the Canon T2i is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 (27 percent) than the Canon 5D Mark II. Moreover, the T2i is substantially lighter (38 percent) than the 5D Mark II. It is worth mentioning in this context that the 5D Mark II 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 Mark II) 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 Mark II gets 850 shots out of its Canon LP-E6 battery, while the T2i can take 440 images on a single charge of its Canon LP-E8 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The T2i was launched at a markedly lower price (by 80 percent) than the 5D Mark II, 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. 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 imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 5D Mark II 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.

With 21MP, the 5D Mark II offers a higher resolution than the T2i (17.9MP), but the 5D Mark II nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.31μm for the T2i) due to its larger sensor. However, the T2i is a somewhat more recent model (by 1 year and 4 months) than the 5D Mark II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 5D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark II for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 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 5D Mark II has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. 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 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 5D Mark II provides substantially higher image quality than the T2i, with an overall score that is 13 points higher. This advantage is based on 1.6 bits higher color depth, 0.4 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 5D Mark II 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 Mark II offers a wider field of view (98%) 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 Mark II 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 following table reports on some other key feature differences and similarities of the Canon 5D Mark II, the Canon T2i, and comparable cameras.

One feature that is present on the 5D Mark II, 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 Mark II 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 Mark II 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 Mark II (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

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

Review summary

So how do things add up? Which of the two cameras – the Canon 5D Mark II or the Canon T2i – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS 5D Mark II:

• More detail: Offers more megapixels (21 vs 17.9MP) with a 8% higher linear resolution.
• Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.6 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
• More complete view: Has a viewfinder with a larger field of view (98% 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.
• Longer lasting: Can take more shots (850 versus 440) on a single battery charge.
• 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 on the market for longer (launched in September 2008).

Reasons to prefer the Canon EOS Rebel T2i:

• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More compact: Is smaller (129x98mm vs 152x114mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 320g or 38 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 (80 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 4 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark II is the clear winner of the match-up (12 : 6 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 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 Mark II 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 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 5D Mark II or the T2i perform in practice. 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 expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
