Canon 400D Comparison Review

The Canon EOS 400D (called Canon XTi in some regions) is a DSLR (Digital Single Lens Reflex) camera that was officially introduced in August 2006 and is equipped with an APS-C sensor. It offers a resolution of 10.1 megapixel.

Is the Canon 400D a good camera? The 400D has a Camera Elo of 1010. This rating puts the 400D below average of all digital single lens reflex cameras. In terms of its sensor size category (APS cameras), the 400D also ranks below average. Based on its within category standings, the camera earns a 2.5-star performance rating. – Well, the Canon 400D is more than 17 years old, and there have been many other good digital cameras released since 2006.

Read on to find out more about the camera's size, sensor, features, reception by expert reviewers, and how it compares to other digital cameras.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon 400D was launched in the US market at a price of $799. 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 with a 35mm slide

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

The Canon 400D features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the Canon 400D among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

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

Sensor Characteristics

It should be noted that unlike many modern cameras, the 400D does not provide the possibility to capture videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 400D has an optical viewfinder that provides a field of view of 95% and a magnification of 0.49x. The adjacent tables list some of the other core features of the Canon 400D along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One convenient feature of the 400D is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Connection comparison

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 400D. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings 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]).

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

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
