Canon 400D vs Nikon D5100
The Canon EOS 400D (called Canon XTi in some regions) and the Nikon D5100 are two digital cameras that were announced, respectively, in August 2006 and April 2011. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 16.1 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 400D and the Nikon D5100? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 400D and the Nikon D5100. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D5100 is notably larger (16 percent) than the Canon 400D. Moreover, the D5100 is slightly heavier (1 percent) than the 400D. In this context, it is worth noting that neither the 400D nor the D5100 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 (400D) and the Nikon Lens Catalog (D5100).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D5100 was somewhat cheaper (by 6 percent) than the 400D at launch, but both cameras fall into the same price category. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 D5100 is 13 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (400D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 16.1MP, the D5100 offers a higher resolution than the 400D (10.1MP), but the D5100 has smaller individual pixels (pixel pitch of 4.80μm versus 5.71μm for the 400D). Yet, the D5100 is a much more recent model (by 4 years and 7 months) than the 400D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon D5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5100 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Canon 400D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D5100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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. Of the two cameras under consideration, the D5100 offers substantially better image quality than the 400D (overall score 18 points higher). The advantage is based on 1.4 bits higher color depth, 2.6 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. 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 D5100 indeed provides for movie recording, while the 400D does not. The highest resolution format that the D5100 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 400D and the D5100 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 D5100 has a higher magnification than the one of the 400D (0.51x 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 400D and Nikon D5100 in connection with corresponding information for a sample of similar cameras.
The Nikon D5100 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 400D writes its imaging data to Compact Flash cards, while the D5100 uses SDXC cards.
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 Nikon D5100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 400D and the D5100 have been discontinued, but can regularly be found used on eBay. The 400D was replaced by the Canon 450D, while the D5100 was followed by the Nikon D5200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what is the bottom line? Which of the two cameras – the Canon 400D or the Nikon D5100 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 400D:
- More compact: Is smaller (127x84mm vs 128x97mm) and thus needs less room in the bag.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Reasons to prefer the Nikon D5100:
- More detail: Has more megapixels (16.1 vs 10.1MP), which boosts linear resolution by 26%.
- Better image quality: Scores substantially higher (18 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x 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 (921k vs 230k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (660 versus 370) out of a single battery charge.
- More modern: Reflects 4 years and 7 months of technical progress since the 400D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the D5100 is the clear winner of the contest (15 : 2 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Nikon D5100 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 D5100. 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.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

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