Canon 550D vs 5D Mark III
The Canon EOS 550D (called Canon T2i in some regions) and the Canon EOS 5D Mark III are two digital cameras that were officially introduced, respectively, in February 2010 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (550D) and a full frame (5D Mark III) sensor. The 550D has a resolution of 17.9 megapixels, whereas the 5D Mark III provides 22.1 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 Canon EOS 5D Mark III? 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: Canon 550D vs 5D Mark III
The physical size and weight of the Canon 550D and the Canon 5D Mark III 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 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 5D Mark III is notably larger (39 percent) than the Canon 550D. Moreover, the 5D Mark III is substantially heavier (79 percent) than the 550D. It is noteworthy in this context that the 5D Mark III 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. A larger imaging sensor (as in the 5D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (550D). You can compare the optics available in the Canon EF Lens Catalog.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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 550D was launched at a markedly lower price (by 80 percent) than the 5D Mark III, 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: Canon 550D vs 5D Mark III
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 550D features an APS-C sensor and the Canon 5D Mark III a full frame sensor. The sensor area in the 5D Mark III 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, the 5D Mark III uses a more advanced image processing engine (DIGIC 5+) than the 550D (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 22.1MP, the 5D Mark III offers a higher resolution than the 550D (17.9MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 4.31μm for the 550D) due to its larger sensor. Moreover, the 5D Mark III is a much more recent model (by 2 years) than the 550D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inch or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inch or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inch or 48.8 x 32.5 cm. The corresponding values for the Canon 550D are 25.9 x 17.3 inch or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inch or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inch or 43.9 x 29.3 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 Canon EOS 5D Mark III are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
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 consideration, the 5D Mark III offers substantially better image quality than the 550D (overall score 15 points higher). The advantage is based on 1.9 bits higher color depth, 0.2 EV in additional dynamic range, and 1.5 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Feature comparison: Canon 550D vs 5D Mark III
Apart from body and sensor, cameras can and do differ across a variety of features. The 550D and the 5D Mark III 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 III 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 5D Mark III 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 550D, the Canon 5D Mark III, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 550D has one, while the 5D Mark III 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 5D Mark III uses Compact Flash or SDXC cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 550D only has one slot.
Connectivity comparison: Canon 550D vs 5D Mark III
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 Canon EOS 5D Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark III has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 550D lacks such a headphone port.
Studio photographers will appreciate that the Canon 5D Mark III (unlike the 550D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 550D and the 5D Mark III have been discontinued, but can regularly be found used on eBay. The 550D was replaced by the Canon 600D, while the 5D Mark III was followed by the Canon 5D Mark IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
Review summary: Canon 550D vs 5D Mark III
So how do things add up? Which of the two cameras – the Canon 550D or the Canon 5D Mark III – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark III is the clear winner of the contest (17 : 5 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 Canon 5D Mark III 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 550D and the 5D Mark III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews: Canon 550D vs 5D Mark III
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
