Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T100 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.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X-T100 and the Ricoh GR III. 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 X-T100 can be obtained in three different colors (black, silver, gold), while the GR III 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 III is considerably smaller (33 percent) than the Fujifilm X-T100. In this context, it is worth noting that neither the X-T100 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 X-T100 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 X-T100 and their specifications in the Fujinon X Lens Catalog.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 III is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
Even though the X-T100 has a slightly larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the X-T100 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.92μm versus 3.91μm for the GR III), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the GR III is a somewhat more recent model (by 8 months) than the X-T100, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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 Fujifilm X-T100 has a native sensitivity range from ISO 200 to ISO 12800, 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).
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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-T100 provides a higher video resolution than the GR III. It can shoot video footage at 4K/15p, while the Ricoh is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T100 has an electronic viewfinder (2360k dots), which can be very helpful 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 table below summarizes some of the other core capabilities of the Fujifilm X-T100 and Ricoh GR III in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The X-T100 has one, while the GR III does not. While the built-in flash of the X-T100 is not very powerful, it can at times be useful as a fill-in light.The X-T100 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the X-T100 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Fujifilm X-T100 and the Ricoh GR III 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 X-T100 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.
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 Fujifilm X-T100 and Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T100 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 X-T100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the X-T100 was succeeded by the Fujifilm X-T200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Ricoh websites.
So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-T100 or the Ricoh GR III – 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 Fujifilm X-T100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video: Provides higher definition movie capture (4K/15p vs 1080/60p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a full-flex 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.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (430 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 on the market for longer (launched in May 2018).
Reasons to prefer the Ricoh GR III:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Has an integrated lens, whereas the X-T100 necessitates an extra lens.
- More compact: Is smaller (109x62mm vs 121x83mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the X-T100).
- 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: Was introduced somewhat (8 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the X-T100 is the clear winner of the match-up (12 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 Fujifilm X-T100 and the Ricoh GR III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings 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 remains incomplete and does no justice, for example, to the way the X-T100 or the GR III perform in practice. 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 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 (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 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.
