Canon 1Ds vs XSi

The Canon EOS-1Ds and the Canon EOS Rebel XSi (labelled Canon 450D in some countries) are two digital cameras that were revealed to the public, respectively, in September 2002 and January 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1Ds) and an APS-C (XSi) sensor. The 1Ds has a resolution of 11 megapixels, whereas the XSi provides 12.2 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 and the Canon EOS Rebel XSi? 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

An illustration of the physical size and weight of the Canon 1Ds and the Canon XSi 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 size dimensions are rounded to the nearest millimeter.

Size Canon 1Ds vs Canon XSi
Compare 1Ds versus XSi top
Comparison 1Ds or XSi rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon XSi is considerably smaller (49 percent) than the Canon 1Ds. Moreover, the XSi is substantially lighter (59 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the XSi 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) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (XSi). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds gets 600 shots out of its NP-E3 battery, while the XSi can take 500 images on a single charge of its LP-E5 power pack. As can be seen in the images above, the 1Ds 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 XSi, Canon provides the BG-E5 vertical grip as an optional accessory (see here on eBay).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The XSi was launched at a markedly lower price (by 91 percent) than the 1Ds, 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 size of the imaging sensor is a crucial determinant 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. 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 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 features a full frame sensor and the Canon XSi an APS-C sensor. The sensor area in the XSi 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.

Technology-wise, the XSi uses a more advanced image processing engine (DIGIC 3) than the 1Ds (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 1Ds and Canon XSi sensor measures

Despite having a smaller sensor, the XSi offers a higher resolution of 12.2 megapixels, compared with 11 MP of the 1Ds. 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 5.19μm versus 8.83μm for the 1Ds). However, it should be noted that the XSi is much more recent (by 5 years and 4 months) than the 1Ds, 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 XSi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XSi for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inch or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inch or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inch or 36.2 x 24.1 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inch or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inch or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inch or 34.4 x 22.9 cm for excellent quality prints.

The Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).

1Ds versus XSi MP

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The XSi offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 1Ds lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the XSi 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 offers a wider field of view (100%) than the one in the XSi (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds has a higher magnification (0.70x vs 0.54x), 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 1Ds and Canon XSi along with similar information for a selection of comparators.

One feature that is present on the 1Ds, but is missing on the XSi 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 writes its imaging data to Compact Flash cards, while the XSi uses SDHC cards.

 

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 and Canon EOS Rebel XSi 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 (unlike the XSi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds and the XSi have been discontinued, but can regularly be found used on eBay. The 1Ds was replaced by the Canon 1Ds Mark II, while the XSi was followed by the Canon T1i. 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

So how do things add up? Which of the two cameras – the Canon 1Ds or the Canon XSi – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS-1Ds:

  • Better low-light sensitivity: Requires less light for good images (0.5 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 0.54x).
  • 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.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (600 versus 500) 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.
  • More heavily discounted: Has been available for much longer (launched in September 2002).


Arguments in favor of the Canon EOS Rebel XSi:

  • More detail: Has more megapixels (12.2 vs 11MP), which boosts linear resolution by 5%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 120k dots).
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (129x98mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 741g or 59 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 (91 percent cheaper at launch).
  • More modern: Reflects 5 years and 4 months of technical progress since the 1Ds launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (10 points each). 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.

1Ds 10:10 XSi

How about other alternatives? Do the specifications of the Canon 1Ds and the Canon XSi 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 1Ds or the XSi 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
