Canon 350D vs Nikon D40

The Canon EOS 350D (called Canon XT in some regions) and the Nikon D40 are two digital cameras that were officially introduced, respectively, in February 2005 and November 2006. 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 350D and the Nikon D40? 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 350D and the Nikon D40. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The 350D can be obtained in two different colors (black, silver), while the D40 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40 is somewhat smaller (2 percent) than the Canon 350D. Moreover, the D40 is slightly lighter (3 percent) than the 350D. In this context, it is worth noting that neither the 350D nor the D40 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 (350D) and the Nikon Lens Catalog (D40).

Concerning battery life, the 350D gets 400 shots out of its Canon NB-2LH battery, while the D40 can take 470 images on a single charge of its Nikon EN-EL9 power pack.

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 naturally be influenced heavily by the price. 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 D40 was launched at a markedly lower price (by 44 percent) than the 350D, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D40 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (350D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon 350D offers a higher resolution of 8 megapixels, compared with 6 MP of the Nikon D40. 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 D40). Moreover, it should be noted that the D40 is a somewhat more recent model (by 1 year and 8 months) than the 350D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 350D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 350D 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 D40 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 350D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.

In terms of underlying technology, the 350D is build around a CMOS sensor, while the D40 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 350D has a notably higher overall DXO score than the D40 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.2 EV of lower dynamic range, and 0.2 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 350D and the D40 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 D40 has a higher magnification than the one of the 350D (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 adjacent table lists some of the other core features of the Canon 350D and Nikon D40 along with similar information for a selection of comparators.

Both the 350D and the D40 have been discontinued, but can regularly be found used on ebay. The 350D was replaced by the Canon 400D, while the D40 was followed by the Nikon D40X. Further information on the features and operation of the 350D and D40 can be found, respectively, in the Canon 350D Manual (free pdf) or the online Nikon D40 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 350D and the Nikon D40? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 350D:

• More detail: Offers more megapixels (8 vs 6MP) with a 15% higher linear resolution.
• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
• More heavily discounted: Has been on the market for longer (launched in February 2005).

Arguments in favor of the Nikon D40:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.49x).
• Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 115k dots).
• Longer lasting: Gets more shots (470 versus 400) out of a single battery charge.
• More affordable: Was introduced into a lower priced category (44 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the D40 emerges as the winner of the match-up (6 : 4 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 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 350D and the Nikon D40 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 350D or the D40. 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
