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 1057. 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. – Well, the Canon 400D is more than 14 years old, and there have been many other good digital cameras released since 2006.

Body comparison with a credit card
An illustration of the physical dimensions of the Canon 400D vis-à-vis a credit card is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter.
The table below summarizes the key physical specs of the Canon 400D alongside a set of comparators. If you want to review a camera pair side-by-side, just select a right-side comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

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 comparator-cameras.

It should be noted that unlike many modern cameras, the 400D does not provide the possibility to capture videos.
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.
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.
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. The table below provides an overview of the connectivity of the Canon EOS 400D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
Canon 400D FAQ
Below are some additional questions and answers concerning some particular features of the 400D.
What is the technology behind the imaging sensor in the 400D?
The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Canon equipped the 400D with the DIGIC II image processor.
What is the ISO sensitivity range of the 400D?
The camera has a native sensitivity range from ISO 100 to ISO 1600.
What is the life expectancy of the shutter in the Canon EOS 400D?
Canon mentions a shutter rating of 50 000 actuations for the 400D. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the 400D over, say, three years, one would have to take about 50 pictures each and every day.
Does the Canon 400D feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The 400D's flash sync speed is 1/200 sec.
Which battery does the 400D use?
The camera gets its power from the NB-2LH (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the 400D?
Yes, Canon offers the BG-E3 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
