Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel T7i and the Ricoh GR III? 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 T7i and the Ricoh GR III 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.

Size Canon T7i vs Ricoh GR III
Compare T7i versus GR III top
Comparison T7i or GR III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR III is considerably smaller (48 percent) than the Canon T7i. In this context, it is worth noting that neither the T7i nor the GR III are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR III has a lens built in, whereas the T7i 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 T7i and their specifications in the Canon EF Lens Catalog.

The power pack in the GR III can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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. 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. 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, but their sensors differ slightly in size. The sensor area in the GR III is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T7i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T7i and Ricoh GR III sensor measures

Even though the GR III has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the GR III has a lower pixel density and larger individual pixels (with a pixel pitch of 3.91μm versus 3.72μm for the T7i), which gives it a potential advantage in terms of light gathering capacity. In addition, the GR III is much more recent (by 2 years) than the T7i, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the GR III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon EOS Rebel T7i 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 III are ISO 100 to ISO 102400 (no boost).

T7i versus GR III MP

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

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the T7i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR III relies on live view and the rear LCD for framing. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Canon T7i and Ricoh GR III along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T7i has one, while the GR III does not. While the built-in flash of the T7i is not very powerful, it can at times be useful as a fill-in light.

The T7i 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 GR III does not have a selfie-screen.

The Ricoh GR III 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 T7i and the GR III 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.

It is notable that the T7i has a microphone port, which is missing on the GR III. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The GR III is a recent model that features in the current product line-up of Ricoh. 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.

Review summary

So how do things add up? Is there a clear favorite between the Canon T7i and the Ricoh GR III? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS Rebel T7i:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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 (6 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 (600 versus 200) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been available for much longer (launched in February 2017).

ilogo

Advantages of the Ricoh GR III:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the T7i requires a separate lens.
  • More compact: Is smaller (109x62mm vs 131x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the T7i).
  • 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 of technical progress since the T7i launch.

If the count of relative strengths (bullet points above) is taken as a measure, the T7i emerges as the winner of the contest (11 : 9 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 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.

T7i 11:09 GR III

How about other alternatives? Do the specifications of the Canon T7i and the Ricoh GR III 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the T7i or the GR III 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.

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], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
