Canon 4000D vs 850D

The Canon EOS 4000D (called Canon T100 in some regions) and the Canon EOS 850D (labelled Canon T8i in some countries) are two digital cameras that were officially introduced, respectively, in February 2018 and February 2020. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 4000D has a resolution of 17.9 megapixels, whereas the 850D provides 24 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 4000D and the Canon EOS 850D? 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 Canon 4000D and the Canon 850D 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 850D is somewhat larger (3 percent) than the Canon 4000D. Moreover, the 850D is markedly heavier (18 percent) than the 4000D. In this context, it is worth noting that neither the 4000D nor the 850D 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 850D can take 800 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.

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 4000D was launched at a markedly lower price (by 47 percent) than the 850D, 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 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. 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 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 850D uses a more advanced image processing engine (DIGIC 8) 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 850D 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 850D 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). However, it should be noted that the 850D is a somewhat more recent model (by 1 year and 11 months) than the 4000D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The resolution advantage of the Canon 850D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 850D 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 850D 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 850D 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.

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"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 850D provides a better video resolution than the 4000D. It can shoot movie footage at 4K/24p, while the 4000D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 4000D and the 850D 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 850D 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 table below summarizes some of the other core capabilities of the Canon 4000D and Canon 850D 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 850D has a touchscreen, while the 4000D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 850D 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.

Concerning the storage of imaging data, both the 4000D and the 850D write their files to SDXC cards. The 850D 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 850D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 850D 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 850D has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the 850D from Canon. Further information on the features and operation of the 4000D and 850D can be found, respectively, in the Canon 4000D Manual (free pdf) or the online Canon 850D Manual.

Review summary

So how do things add up? Is the Canon 4000D better than the Canon 850D or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 4000D:

• Less heavy: Is lighter (by 79g or 15 percent) and hence easier to carry around.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2018).

Advantages of the Canon EOS 850D:

• 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 8 vs DIGIC 4+).
• Better video: Provides higher definition movie capture (4K/24p vs 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 (7.5 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 (800 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 modern: Was introduced somewhat (1 year and 11 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 850D is the clear winner of the contest (17 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 850D 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 4000D or the 850D. 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.

Care should be taken when interpreting the review scores above, 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.
