Canon 1D Mark III vs XTi
The Canon EOS-1D Mark III and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were announced, respectively, in February 2007 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and an APS-C (XTi) sensor. Both cameras offer a resolution of 10.1 megapixels.
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 XTi? 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.
The physical size and weight of the Canon 1D Mark III and the Canon XTi are illustrated 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 XTi is considerably smaller (56 percent) than the Canon 1D Mark III. Moreover, the XTi is substantially lighter (52 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 XTi 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 (XTi). 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 XTi can take 370 images on a single charge of its NB-2LH 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 XTi, Canon provides the BG-E3 vertical grip as an optional accessory (see here on eBay).

The price is, of course, an important factor in any camera decision. 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 XTi was launched at a markedly lower price (by 82 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 1D Mark III features an APS-H sensor and the Canon XTi an APS-C sensor. The sensor area in the XTi 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.
In terms of chip-set technology, the 1D Mark III uses a more advanced image processing engine (DIGIC III) than the XTi (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
Even though the 1D Mark III has a larger sensor, both cameras offer the same resolution of 10.1 megapixels. This implies that the 1D Mark III has a lower pixel density and larger individual pixels (with a pixel pitch of 7.21μm versus 5.71μm for the XTi), which gives it a potential advantage in terms of light gathering capacity. In addition, the 1D Mark III is a somewhat more recent model (by 5 months) than the XTi, and its sensor might have benefitted from technological advances during this time.
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 XTi are ISO 100 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 1D Mark III has a notably higher overall DXO score than the XTi (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.7 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark III and the XTi 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 XTi (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 0.49x), 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 1D Mark III, the Canon XTi, and comparable cameras.

One feature that is present on the 1D Mark III, but is missing on the XTi 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 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the XTi uses Compact Flash cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the XTi only has one slot.
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-1D Mark III and Canon EOS Rebel XTi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1D Mark III (unlike the XTi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1D Mark III and the XTi have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the 1D Mark III was followed by the Canon 1D 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.
So what conclusions can be drawn? Is there a clear favorite between the Canon 1D Mark III and the Canon XTi? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS-1D Mark III:
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC III vs DIGIC II).
- 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 (0.58x vs 0.49x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (2200 versus 370) 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.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Is somewhat more recent (announced 5 months after the XTi).
Arguments in favor of the Canon EOS Rebel XTi:
- More compact: Is smaller (127x84mm vs 156x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 599g or 52 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 (82 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2006).
If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark III is the clear winner of the match-up (16 : 5 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 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 1D Mark III and the Canon XTi 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 remains incomplete and does no justice, for example, to the way the 1D Mark III or the XTi 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.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
