Canon 1D Mark II vs XTi

The Canon EOS-1D Mark II and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were revealed to the public, respectively, in January 2004 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark II) and an APS-C (XTi) sensor. The 1D Mark II has a resolution of 8.2 megapixels, whereas the XTi provides 10.1 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-1D Mark II 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.

Body comparison

The physical size and weight of the Canon 1D Mark II 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 (57 percent) than the Canon 1D Mark II. Moreover, the XTi is substantially lighter (64 percent) than the 1D Mark II. It is worth mentioning in this context that the 1D Mark II 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 II) 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 II gets 1200 shots out of its Canon NP-E3 battery, while the XTi can take 370 images on a single charge of its Canon NB-2LH power pack. As can be seen in the images above, the 1D Mark II 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).

Any camera decision will obviously take relative prices into account. 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 II, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 II features an APS-H sensor and the Canon XTi an APS-C sensor. The sensor area in the XTi is 40 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.

Despite having a smaller sensor, the XTi offers a higher resolution of 10.1 megapixels, compared with 8.2 MP of the 1D Mark II. 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 5.71μm versus 8.17μm for the 1D Mark II). However, it should be noted that the XTi is much more recent (by 2 years and 6 months) than the 1D Mark II, 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 XTi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XTi for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 cm. The corresponding values for the Canon 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The Canon EOS-1D Mark II 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 XTi are ISO 100 to ISO 1600 (no boost).

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 II has a notably higher overall DXO score than the XTi (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.2 bits higher color depth, 0.1 EV in additional dynamic range, and 0.6 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark II 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 II 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 II has a higher magnification (0.55x vs 0.49x), 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 II and Canon XTi along with similar information for a selection of comparators.

One feature that is present on the 1D Mark II, 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 II writes its imaging data to Compact Flash or SD cards, while the XTi uses Compact Flash cards. The 1D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the XTi only has one slot.

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-1D Mark II 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 II (unlike the XTi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark II and the XTi have been discontinued, but can regularly be found used on ebay. The 1D Mark II was replaced by the Canon 1D Mark II N, while the XTi was followed by the Canon Xsi. Further information on the features and operation of the 1D Mark II and XTi can be found, respectively, in the Canon 1D Mark II Manual (free pdf) or the online Canon XTi Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1D Mark II and the Canon XTi? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS-1D Mark II:

• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
• 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 (0.55x vs 0.49x).
• 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.
• Faster burst: Shoots at higher frequency (8.3 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 (1200 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 heavily discounted: Has been available for much longer (launched in January 2004).

Arguments in favor of the Canon EOS Rebel XTi:

• More detail: Has more megapixels (10.1 vs 8.2MP), which boosts linear resolution by 11%.
• Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
• More compact: Is smaller (127x84mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 979g or 64 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
• More modern: Reflects 2 years and 6 months of technical progress since the 1D Mark II launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 1D Mark II is the clear winner of the match-up (13 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 1D Mark II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark II or the XTi. 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 where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
