Nikon D3400 vs Canon 400D

The Nikon D3400 and the Canon EOS 400D (labelled Canon XTi in some countries) are two digital cameras that were officially introduced, respectively, in August 2016 and August 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Nikon has a resolution of 24 megapixels, whereas the Canon 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 Nikon D3400 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

The physical size and weight of the Nikon D3400 and the Canon 400D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The D3400 can be obtained in two different colors (black, red), 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 400D is notably smaller (12 percent) than the Nikon D3400. However, the 400D is markedly heavier (25 percent) than the D3400. In this context, it is worth noting that neither the D3400 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. 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 Nikon Lens Catalog (D3400) and the Canon EF Lens Catalog (400D).

Concerning battery life, the D3400 gets 1200 shots out of its Nikon EN-EL14a battery, while the 400D can take 370 images on a single charge of its Canon NB-2LH power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 D3400 was launched at a markedly lower price (by 38 percent) than the 400D, which puts it into a different market segment. 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 10 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (D3400) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24MP, the D3400 offers a higher resolution than the 400D (10.1MP), but the D3400 has smaller individual pixels (pixel pitch of 3.91μm versus 5.71μm for the 400D). However, the D3400 is a much more recent model (by 9 years and 11 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. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D3400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3400 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 Nikon D3400 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon EOS 400D are ISO 100 to ISO 1600 (no boost).

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 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"). Of the two cameras under review, the D3400 provides substantially higher image quality than the 400D, with an overall score that is 24 points higher. This advantage is based on 2.7 bits higher color depth, 2.9 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The D3400 indeed provides movie recording capabilities, while the 400D does not. The highest resolution format that the D3400 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D3400 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 D3400 has a higher magnification than the one of the 400D (0.57x 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 Nikon D3400 and Canon 400D in connection with corresponding information for a sample of similar cameras.

The D3400 writes its imaging data to SDXC cards, while the 400D uses Compact Flash cards.

Connectivity comparison

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 Nikon D3400 and Canon EOS 400D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D3400 and the 400D have been discontinued, but can regularly be found used on ebay. The 400D was replaced by the Canon 450D, while the D3400 was followed by the Nikon D3500. Further information on the features and operation of the D3400 and 400D can be found, respectively, in the Nikon D3400 Manual (free pdf) or the online Canon 400D Manual.

Review summary

So how do things add up? Is the Nikon D3400 better than the Canon 400D or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Nikon D3400:

• More detail: Offers more megapixels (24 vs 10.1MP) with a 54% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.7 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.57x 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).
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 111g or 20 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (1200 versus 370) on a single battery charge.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More modern: Reflects 9 years and 11 months of technical progress since the 400D launch.

Advantages of the Canon EOS 400D:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More compact: Is smaller (127x84mm vs 124x98mm) and will fit more readily into a bag.
• 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 D3400 is the clear winner of the match-up (16 : 3 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 Nikon D3400 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 D3400 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

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 (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.

Note: (+ +) 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
