Canon 450D vs Nikon D100

The Canon EOS 450D (called Canon XSi in some regions) and the Nikon D100 are two digital cameras that were officially introduced, respectively, in January 2008 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 12.2 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 450D 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: Canon 450D vs Nikon D100

The physical size and weight of the Canon 450D and the Nikon D100 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 size dimensions are rounded to the nearest millimeter.

Size Canon 450D vs Nikon D100
Compare 450D versus D100 top
Comparison 450D 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 (32 percent) than the Canon 450D. Moreover, the D100 is substantially heavier (49 percent) than the 450D. In this context, it is worth noting that neither the 450D 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 (450D) and the Nikon Lens Catalog (D100).

Concerning battery life, the 450D gets 500 shots out of its LP-E5 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 want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 450D was launched at a markedly lower price (by 60 percent) than the D100, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Canon 450D vs Nikon D100

The size of the imaging sensor is a crucial determinant 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.

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 (450D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 450D and Nikon D100 sensor measures

Despite having a smaller sensor, the Canon 450D offers a higher resolution of 12.2 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 5.19μm versus 7.85μm for the D100). However, it should be noted that the 450D is much more recent (by 5 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 450D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 450D 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 Nikon D100 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.

The Canon EOS 450D 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.

450D versus D100 MP

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").

The 450D offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The D100 lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison: Canon 450D vs Nikon D100

Apart from body and sensor, cameras can and do differ across a variety of features. The 450D 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 450D has a higher magnification than the one of the D100 (0.54x vs 0.53x), 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 450D and Nikon D100 along with similar information for a selection of comparators.

One feature that is present on the D100, but is missing on the 450D 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 450D writes its imaging data to SDHC cards, while the D100 uses Compact Flash cards.

Both the 450D and the D100 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the 450D was followed by the Canon 500D. 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: Canon 450D vs Nikon D100

So what is the bottom line? Which of the two cameras – the Canon 450D or the Nikon D100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon EOS 450D:

  • More detail: Offers more megapixels (12.2 vs 6MP) with a 42% higher linear resolution.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.53x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (129x98mm vs 144x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 256g or 33 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (500 versus 370) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
  • More modern: Reflects 5 years and 11 months of technical progress since the D100 launch.

ilogo

Arguments in favor of the Nikon D100:

  • 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 count of relative strengths (bullet points above) is taken as a measure, the 450D is the clear winner of the match-up (11 : 2 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.

450D 11:02 D100

How about other alternatives? Do the specifications of the Canon 450D 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 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 450D or the D100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Canon 450D vs Nikon D100

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 (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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
