Canon 1D Mark III vs T3i
The Canon EOS-1D Mark III and the Canon EOS Rebel T3i (labelled Canon 600D in some countries) are two digital cameras that were announced, respectively, in February 2007 and February 2011. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and an APS-C (T3i) sensor. The 1D Mark III has a resolution of 10.1 megapixels, whereas the T3i 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-1D Mark III and the Canon EOS Rebel T3i? 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 1D Mark III vs T3i
An illustration of the physical size and weight of the Canon 1D Mark III and the Canon T3i 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 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 T3i is considerably smaller (46 percent) than the Canon 1D Mark III. Moreover, the T3i is substantially lighter (51 percent) than the 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the T3i 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 1D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T3i). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the T3i can take 440 images on a single charge of its LP-E8 power pack. As can be seen in the images above, the 1D Mark III 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 T3i, Canon provides the BG-E8 vertical grip as an optional accessory (see here on eBay).

|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 T3i was launched at a markedly lower price (by 87 percent) than the 1D Mark III, 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: Canon 1D Mark III vs T3i
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. 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 1D Mark III features an APS-H sensor and the Canon T3i an APS-C sensor. The sensor area in the T3i is 37 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the T3i uses a more advanced image processing engine (DIGIC 4) than the 1D Mark III (DIGIC III), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the T3i offers a higher resolution of 17.9 megapixels, compared with 10.1 MP of the 1D Mark III. 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 7.21μm for the 1D Mark III). However, it should be noted that the T3i is much more recent (by 3 years and 11 months) than the 1D Mark III, 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 T3i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Canon EOS Rebel T3i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
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 1D Mark III has a notably higher overall DXO score than the T3i (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.2 EV in additional dynamic range, and 0.4 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 T3i indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the T3i can use is 1080/30p.
Feature comparison: Canon 1D Mark III vs T3i
Apart from body and sensor, cameras can and do differ across a range of features. The 1D Mark III and the T3i 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 1D Mark III offers a wider field of view (100%) than the one in the T3i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark III has a higher magnification (0.58x vs 0.53x), 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 1D Mark III and Canon T3i along with similar information for a selection of comparators.

One feature that is present on the 1D Mark III, but is missing on the T3i 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 T3i has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 1D Mark III does not have a selfie-screen.
The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the T3i uses SDXC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the T3i only has one slot.
Connectivity comparison: Canon 1D Mark III vs T3i
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.

If the count of individual advantages (bullet points above) is taken as a guide, the 1D Mark III emerges as the winner of the contest (13 : 11 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 1D Mark III and the Canon T3i 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 says little about, for example, the shooting experience and imaging performance of the 1D Mark III and the T3i 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 1D Mark III vs T3i
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 (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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
