Canon T7i vs Nikon D3400
The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Nikon D3400 are two digital cameras that were officially introduced, respectively, in February 2017 and August 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.
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 Rebel T7i and the Nikon D3400? 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 T7i and the Nikon D3400. 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 width, height and depth dimensions are rounded to the nearest millimeter.
The D3400 can be obtained in two different colors (black, red), while the T7i 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 Nikon D3400 is notably smaller (7 percent) than the Canon T7i. Moreover, the D3400 is markedly lighter (16 percent) than the T7i. In this context, it is worth noting that neither the T7i nor the D3400 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 (T7i) and the Nikon Lens Catalog (D3400).
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The D3400 was launched at a markedly lower price (by 33 percent) than the T7i, 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.
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 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. 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 tend to be more expensive and 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 D3400 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T7i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
Even though the D3400 has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the D3400 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.91μm versus 3.72μm for the T7i), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the T7i is a somewhat more recent model (by 5 months) than the D3400, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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 T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T7i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Nikon D3400 are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The T7i and the D3400 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 T7i (0.57x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon T7i and Nikon D3400 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T7i has a touchscreen, while the D3400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T7i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D3400 does not have a selfie-screen.
Concerning the storage of imaging data, both the T7i and the D3400 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Rebel T7i and Nikon D3400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i has a microphone port, which is missing on the D3400. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the T7i and the D3400 have been discontinued, but can regularly be found used on eBay. The D3400 was replaced by the Nikon D3500, while the T7i was followed by the Canon T8i. 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 how do things add up? Is there a clear favorite between the Canon T7i and the Nikon D3400? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS Rebel T7i:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Is somewhat more recent (announced 5 months after the D3400).
Arguments in favor of the Nikon D3400:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.57x vs 0.51x).
- Less heavy: Has a lower weight (by 87g or 16 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (1200 versus 600) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the T7i is the clear winner of the match-up (11 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 T7i and the Nikon D3400 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 says little about, for example, the shooting experience and imaging performance of the T7i and the D3400 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
