Canon 1Ds Mark II vs XTi

The Canon EOS-1Ds Mark II and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were officially introduced, respectively, in September 2004 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds Mark II) and an APS-C (XTi) sensor. The 1Ds Mark II has a resolution of 16.6 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-1Ds 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 1Ds 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 views from the front, the top, and the rear side 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 XTi is considerably smaller (57 percent) than the Canon 1Ds Mark II. Moreover, the XTi is substantially lighter (54 percent) than the 1Ds Mark II. It is worth mentioning in this context that the 1Ds 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 1Ds 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 1Ds Mark II gets 1200 shots out of its NP-E3 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 1Ds 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).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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 XTi was launched at a markedly lower price (by 90 percent) than the 1Ds 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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark II features a full frame sensor and the Canon XTi an APS-C sensor. The sensor area in the XTi 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 16.6MP, the 1Ds Mark II offers a higher resolution than the XTi (10.1MP), but the 1Ds Mark II nevertheless has larger individual pixels (pixel pitch of 7.21μm versus 5.71μm for the XTi) due to its larger sensor. However, the XTi is a somewhat more recent model (by 1 year and 11 months) than the 1Ds 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 1Ds Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark II for good quality output (200 dots per inch) amounts to 25 x 16.6 inches or 63.4 x 42.3 cm, for very good quality (250 dpi) 20 x 13.3 inches or 50.7 x 33.8 cm, and for excellent quality (300 dpi) 16.6 x 11.1 inches or 42.3 x 28.2 cm. The corresponding values for the Canon XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon EOS-1Ds 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.

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 1Ds Mark II provides substantially higher image quality than the XTi, with an overall score that is 12 points higher. This advantage is based on 1.2 bits higher color depth, 0.3 EV in additional dynamic range, and 1.2 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 1Ds 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 1Ds 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 1Ds Mark II has a higher magnification (0.70x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1Ds Mark II and Canon XTi in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1Ds 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 1Ds Mark II writes its imaging data to Compact Flash or SDHC cards, while the XTi uses Compact Flash cards. The 1Ds 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-1Ds 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 1Ds Mark II (unlike the XTi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

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

Review summary

So how do things add up? Is there a clear favorite between the Canon 1Ds 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-1Ds Mark II:

• More detail: Offers more megapixels (16.6 vs 10.1MP) with a 28% higher linear resolution.
• Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.2 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 (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x 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 (4 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 on the market for longer (launched in September 2004).

Reasons to prefer the Canon EOS Rebel XTi:

• 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 659g or 54 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 (90 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 1Ds Mark II is the clear winner of the match-up (15 : 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 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 1Ds 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 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 1Ds Mark II or the XTi perform in practice. 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 why hands-on reviews by experts are important. 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. 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.
