Canon 250D vs 20D
The Canon EOS 250D (called Canon SL3 in some regions) and the Canon EOS 20D are two digital cameras that were revealed to the public, respectively, in April 2019 and August 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 250D has a resolution of 24 megapixels, whereas the 20D provides 8.2 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 250D and the Canon EOS 20D? 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 physical size and weight of the Canon 250D and the Canon 20D 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 250D can be obtained in two different colors (black, white), while the 20D 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 20D is notably larger (35 percent) than the Canon 250D. Moreover, the 20D is substantially heavier (71 percent) than the 250D. In this context, it is worth noting that neither the 250D nor the 20D 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full 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 250D was launched at a markedly lower price (by 60 percent) than the 20D, 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 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. 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 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 20D is 2 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of chip-set technology, the 250D uses a more advanced image processing engine (DIGIC 8) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Canon 250D offers a higher resolution of 24 megapixels, compared with 8.2 MP of the Canon 20D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 6.42μm for the 20D). However, it should be noted that the 250D is much more recent (by 14 years and 7 months) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon 250D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 250D 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 20D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.
The 250D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 250D 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 Canon EOS 20D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The 250D indeed provides movie recording capabilities, while the 20D does not. The highest resolution format that the 250D can use is 4K/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 250D and the 20D 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 20D has a higher magnification than the one of the 250D (0.56x vs 0.54x), 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 250D and Canon 20D 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 250D has a touchscreen, while the 20D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The 250D 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 20D does not have a selfie-screen.
The Canon 250D 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.
The 250D writes its imaging data to SDXC cards, while the 20D uses Compact Flash cards.
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 250D and Canon EOS 20D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 250D offers wifi support, while the 20D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Canon 20D (unlike the 250D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The 250D is a recent model that features in the current product line-up of Canon. In contrast, the 20D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 20D was succeeded by the Canon 30D. 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 how do things add up? Is the Canon 250D better than the Canon 20D or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 250D:
- More detail: Offers more megapixels (24 vs 8.2MP) with a 71% higher linear resolution.
- Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 2).
- Broader imaging potential: Can record not only still images but also 4K/25p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 118k 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.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (122x93mm vs 144x106mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 321g or 42 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (1070 versus 700) on a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- 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 affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
- More modern: Reflects 14 years and 7 months of technical progress since the 20D launch.
Advantages of the Canon EOS 20D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.54x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in August 2004).
If the number of relative strengths (bullet points above) is taken as a guide, the 250D is the clear winner of the match-up (18 : 5 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 250D and the Canon 20D 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 says little about, for example, the shooting experience and imaging performance of the 250D and the 20D 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 adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated with care, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
