Canon XT vs Nikon D100

The Canon EOS Rebel XT (called Canon 350D in some regions) and the Nikon D100 are two digital cameras that were officially introduced, respectively, in February 2005 and February 2002. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 8 megapixels, whereas the Nikon provides 6 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 Rebel XT and the Nikon D100? 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 side-by-side display below illustrates the physical size and weight of the Canon XT and the Nikon D100. 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.

The XT can be obtained in two different colors (black, silver), while the D100 is only available in black.

Size Canon XT vs Nikon D100
Compare XT versus D100 top
Comparison XT or D100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D100 is notably larger (40 percent) than the Canon XT. Moreover, the D100 is substantially heavier (44 percent) than the XT. In this context, it is worth noting that neither the XT nor the D100 are weather-sealed.

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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (XT) and the Nikon Lens Catalog (D100).

Concerning battery life, the XT gets 400 shots out of its NB-2LH battery, while the D100 can take 370 images on a single charge of its EN-EL3 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The XT was launched at a markedly lower price (by 55 percent) than the D100, 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 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. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D100 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (XT) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon XT and Nikon D100 sensor measures

Despite having a smaller sensor, the Canon XT offers a higher resolution of 8 megapixels, compared with 6 MP of the Nikon D100. 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 6.41μm versus 7.85μm for the D100). However, it should be noted that the XT is much more recent (by 2 years and 11 months) than the D100, 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 XT implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XT for good quality output (200 dots per inch) amounts to 17.3 x 11.5 inches or 43.9 x 29.3 cm, for very good quality (250 dpi) 13.8 x 9.2 inches or 35.1 x 23.4 cm, and for excellent quality (300 dpi) 11.5 x 7.7 inches or 29.3 x 19.5 cm. The corresponding values for the Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Canon EOS Rebel XT has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D100 are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-1600.

XT versus D100 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.
Neither the XT nor the D100 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The XT and the D100 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the D100 has a higher magnification than the one of the XT (0.53x 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 XT and Nikon D100 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D100, but is missing on the XT 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.

Concerning the storage of imaging data, both the XT and the D100 write their files to Compact Flash 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.

Both the XT and the D100 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the XT was followed by the Canon Xti. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

Review summary

So how do things add up? Is there a clear favorite between the Canon XT and the Nikon D100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon EOS Rebel XT:

  • More detail: Offers more megapixels (8 vs 6MP) with a 15% higher linear resolution.
  • More compact: Is smaller (127x94mm vs 144x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 240g or 31 percent) and hence easier to carry around.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
  • More modern: Reflects 2 years and 11 months of technical progress since the D100 launch.

ilogo

Advantages of the Nikon D100:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.49x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More heavily discounted: Has been around for much longer (launched in February 2002).

If the number of relative strengths (bullet points above) is taken as a guide, the XT emerges as the winner of the contest (6 : 3 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

XT 06:03 D100

How about other alternatives? Do the specifications of the Canon XT and the Nikon D100 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 XT or the D100 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
