Canon 100D vs 400D
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 400D (labelled Canon XTi in some countries) are two digital cameras that were officially introduced, respectively, in March 2013 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 100D has a resolution of 17.9 megapixels, whereas the 400D provides 10.1 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 100D and the Canon EOS 400D? 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 100D vs 400D
The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon 400D. 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 100D can be obtained in two different colors (black, white), 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 100D and the Canon 400D are of equal size. However, the 400D is substantially heavier (37 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the 400D 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 100D was launched at a markedly lower price (by 31 percent) than the 400D, 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 100D vs 400D
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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 400D is 1 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of chip-set technology, the 100D uses a more advanced image processing engine (DIGIC 5) than the 400D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
With 17.9MP, the 100D offers a higher resolution than the 400D (10.1MP), but the 100D has smaller individual pixels (pixel pitch of 4.31μm versus 5.71μm for the 400D). However, the 100D is a much more recent model (by 6 years and 6 months) than the 400D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 400D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 400D are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.

Many modern cameras cannot only take still pictures, but also record videos. The 100D indeed provides movie recording capabilities, while the 400D does not. The highest resolution format that the 100D can use is 1080/30p.
Feature comparison: Canon 100D vs 400D
Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 400D 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 100D has a higher magnification than the one of the 400D (0.54x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 100D and Canon 400D in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the 400D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The 100D writes its imaging data to SDXC cards, while the 400D uses Compact Flash cards.
Connectivity comparison: Canon 100D vs 400D
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 100D and Canon EOS 400D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the 400D have been discontinued, but can regularly be found used on eBay. The 400D was replaced by the Canon 450D, while the 100D was followed by the Canon 200D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
Review summary: Canon 100D vs 400D
So how do things add up? Is there a clear favorite between the Canon 100D and the Canon 400D? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 10.1MP) with a 33% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC II).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.49x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (4.9 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Is lighter (by 149g or 27 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 6 years and 6 months of technical progress since the 400D launch.
Advantages of the Canon EOS 400D:
- More heavily discounted: Has been around for much longer (launched in August 2006).
If the number of relative strengths (bullet points above) is taken as a guide, the 100D is the clear winner of the match-up (13 : 1 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.
How about other alternatives? Do the specifications of the Canon 100D and the Canon 400D 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 100D or the 400D perform in practice. 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: Canon 100D vs 400D
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 (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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
