Canon 100D vs 850D
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 850D (labelled Canon T8i in some countries) are two digital cameras that were officially introduced, respectively, in March 2013 and February 2020. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 100D 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 100D 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.
The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon 850D. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The 100D can be obtained in two different colors (black, white), while the 850D 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 850D is notably larger (27 percent) than the Canon 100D. Moreover, the 850D is markedly heavier (27 percent) than the 100D. In this context, it is worth noting that neither the 100D 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.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 100D was launched at a markedly lower price (by 27 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 850D uses a more advanced image processing engine (DIGIC 8) than the 100D (DIGIC 5), 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 100D. 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 100D). However, it should be noted that the 850D is much more recent (by 6 years and 10 months) than the 100D, and its sensor will have benefitted from technological advances during this time that 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 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inch or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inch or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inch or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 850D provides a better video resolution than the 100D. It can shoot movie footage at 4K/24p, while the 100D is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 100D 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 100D has a higher magnification than the one of the 850D (0.54x vs 0.51x), 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 100D and Canon 850D in connection with corresponding information for a sample of similar cameras.

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 100D and the 850D 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 100D 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 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.
The 850D is a recent model that features in the current product line-up of Canon. In contrast, the 100D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 100D was succeeded by the Canon 200D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon 100D better than the Canon 850D or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 100D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.51x).
- More compact: Is smaller (117x91mm vs 131x103mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 108g or 21 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2013).
Reasons to prefer 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 5).
- Better video: Provides higher definition movie capture (4K/24p vs 1080/30p).
- 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 (7.5 vs 4.9 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 380) out of a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 6 years and 10 months of technical progress since the 100D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the 850D is the clear winner of the contest (11 : 5 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 100D 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the 850D perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
