Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 250D and the Ricoh GR IIIx? 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 250D and the Ricoh GR IIIx is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The 250D can be obtained in two different colors (black, white), while the GR IIIx 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 Ricoh GR IIIx is considerably smaller (40 percent) than the Canon 250D. In this context, it is worth noting that neither the 250D nor the GR IIIx are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR IIIx has a lens built in, whereas the 250D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 250D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 250D gets 1070 shots out of its Canon LP-E17 battery, while the GR IIIx can take 200 images on a single charge of its Ricoh DB-110 power pack. The power pack in the GR IIIx can be charged via the USB port, which can be very convenient when travelling.

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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 GR IIIx is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (250D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the GR IIIx has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the GR IIIx has a lower pixel density and larger individual pixels (with a pixel pitch of 3.91μm versus 3.72μm for the 250D), which gives it a potential advantage in terms of light gathering capacity. In addition, the GR IIIx is much more recent (by 2 years and 4 months) than the 250D, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the GR IIIx has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).

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 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 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 250D provides a higher video resolution than the GR IIIx. It can shoot video footage at 4K/25p, while the Ricoh is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 250D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR IIIx relies on live view and the rear LCD for framing. That said, the GR IIIx can be equipped with an optional viewfinder – the GV-3. The adjacent table lists some of the other core features of the Canon 250D and Ricoh GR IIIx along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 250D has one, while the GR IIIx does not. While the built-in flash of the 250D is not very powerful, it can at times be useful as a fill-in light.

The Canon 250D and the Ricoh GR IIIx both have 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 250D and the GR IIIx 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.

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 250D and Ricoh GR IIIx and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 250D has a microphone port, which is missing on the GR IIIx. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the 250D and the GR IIIx are recent models that are part of the current product line-up. The 250D replaced the earlier Canon 200D, while the GR IIIx followed on from the Ricoh GR II. Further information on the features and operation of the 250D and GR IIIx can be found, respectively, in the Canon 250D Manual (free pdf) or the online Ricoh GR IIIx Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 250D or the Ricoh GR IIIx – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 250D:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher definition movie capture (4K/25p vs 1080/60p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 (5 vs 4 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (1070 versus 200) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More heavily discounted: Has been available for much longer (launched in April 2019).

Arguments in favor of the Ricoh GR IIIx:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Ready to shoot: Comes with an integrated lens, while the 250D requires a separate lens.
• More compact: Is smaller (109x62mm vs 122x93mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 250D).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• More modern: Reflects 2 years and 4 months of technical progress since the 250D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 250D emerges as the winner of the contest (11 : 8 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 Ricoh GR IIIx place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 250D or the GR IIIx. 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.

Expert reviews

This is where reviews by experts come in. 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 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.
