Canon 400D vs 350D

The Canon EOS 400D (called Canon XTi in some regions) and the Canon EOS 350D (labelled Canon XT in some countries) are two digital cameras that were announced, respectively, in August 2006 and February 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 400D has a resolution of 10.1 megapixels, whereas the 350D provides 8 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 400D and the Canon EOS 350D? 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 400D and the Canon 350D 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 width, height and depth measures are rounded to the nearest millimeter.

The 350D can be obtained in two different colors (black, silver), while the 400D 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 Canon 350D is notably larger (12 percent) than the Canon 400D. However, the 350D is slightly lighter (3 percent) than the 400D. In this context, it is worth noting that neither the 400D nor the 350D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 400D was launched at a somewhat lower price (by 11 percent) than the 350D, which makes it more attractive for photographers on a tight budget. 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.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the 400D offers a higher resolution of 10.1 megapixels, compared with 8 MP of the 350D. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the 400D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.71μm versus 6.41μm for the 350D). In this context, it should be noted, however, that the 400D is a somewhat more recent model (by 1 year and 6 months) than the 350D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The resolution advantage of the Canon 400D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 400D for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inches or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inches or 32.9 x 21.9 cm. The corresponding values for the Canon 350D are 17.3 x 11.5 inches or 43.9 x 29.3 cm for good quality, 13.8 x 9.2 inches or 35.1 x 23.4 cm for very good quality, and 11.5 x 7.7 inches or 29.3 x 19.5 cm for excellent quality prints.

The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The Canon EOS 350D offers exactly the same ISO settings.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 400D and the 350D 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%), as well as the same magnification (0.49x). The following table reports on some other key feature differences and similarities of the Canon 400D, the Canon 350D, and comparable cameras.

Both the 400D and the 350D have been discontinued, but can regularly be found used on ebay. The 350D was replaced by the Canon 400D, while the 400D was followed by the Canon 450D. Further information on the features and operation of the 400D and 350D can be found, respectively, in the Canon 400D Manual (free pdf) or the online Canon 350D Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 400D and the Canon 350D? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS 400D:

• More detail: Offers more megapixels (10.1 vs 8MP) with a 12% higher linear resolution.
• 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).
• More compact: Is smaller (127x84mm vs 127x94mm) and thus needs less room in the bag.
• More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 6 months after the 350D).

Reasons to prefer the Canon EOS 350D:

• More heavily discounted: Has been on the market for longer (launched in February 2005).

If the count of relative strengths (bullet points above) is taken as a measure, the 400D is the clear winner of the match-up (6 : 1 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 400D and the Canon 350D 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 400D or the 350D. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
