Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 4000D and the Canon EOS Rebel T7i? 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

An illustration of the physical size and weight of the Canon 4000D and the Canon T7i is provided 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 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 Canon 4000D and the Canon T7i are of equal size. However, the T7i is markedly heavier (22 percent) than the 4000D. In this context, it is worth noting that neither the 4000D nor the T7i 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.

Concerning battery life, the 4000D gets 500 shots out of its Canon LP-E10 battery, while the T7i can take 600 images on a single charge of its Canon LP-E17 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will naturally be influenced heavily by the price. 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 4000D was launched at a markedly lower price (by 47 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.

Sensor comparison

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the T7i uses a more advanced image processing engine (DIGIC 7) than the 4000D (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the T7i offers a higher resolution of 24 megapixels, compared with 17.9 MP of the 4000D. This megapixels advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the T7i has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the 4000D). Moreover, it should be noted, that the 4000D is a somewhat more recent model (by 1 year) than the T7i, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

The resolution advantage of the Canon T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i 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 4000D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 4000D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Canon EOS Rebel T7i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the T7i provides a faster frame rate than the 4000D. It can shoot movie footage at 1080/60p, while the 4000D is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 4000D and the T7i 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 T7i has a higher magnification than the one of the 4000D (0.51x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 4000D, the Canon T7i, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T7i has a touchscreen, while the 4000D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Concerning the storage of imaging data, both the 4000D and the T7i write their files to SDXC cards. The T7i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 4000D cannot take advantage of Ultra High Speed SD 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 Canon EOS 4000D and Canon EOS Rebel T7i 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 can help to improve the quality of audio recordings by attaching an external microphone. The 4000D does not feature such a mic input.

The 4000D is a recent model that features in the current product line-up of Canon. In contrast, the T7i has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the T7i was succeeded by the Canon T8i. Further information on the features and operation of the 4000D and T7i can be found, respectively, in the Canon 4000D Manual (free pdf) or the online Canon T7i Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon 4000D or the Canon T7i – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS 4000D:

• Less heavy: Is lighter (by 96g or 18 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year after the T7i).

Reasons to prefer the Canon EOS Rebel T7i:

• More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
• Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 4+).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• 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.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.50x).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (600 versus 500) out of a single battery charge.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been on the market for longer (launched in February 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the T7i is the clear winner of the contest (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 Canon 4000D and the Canon T7i 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 4000D or the T7i. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
