Body comparison

The physical size and weight of the Fujifilm X-Pro3 and the Ricoh GR IIIx 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 width, height and depth dimensions are rounded to the nearest millimeter.

The X-Pro3 can be obtained in two different colors (black, silver), while the GR IIIx is only available in black.

Size Fujifilm X-Pro3 vs Ricoh GR IIIx
Compare X-Pro3 versus GR IIIx top
Comparison X-Pro3 or GR IIIx rear

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 (42 percent) than the Fujifilm X-Pro3. It is worth mentioning in this context that the X-Pro3 is splash and dust resistant, while the GR IIIx does not feature any corresponding weather-sealing.

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 X-Pro3 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-Pro3 and their specifications in the Fujinon X Lens Catalog.

Concerning battery life, the X-Pro3 gets 440 shots out of its Fujifilm NP-W126S battery, while the GR IIIx can take 200 images on a single charge of its Ricoh DB-110 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Note: 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GR IIIx was launched at a lower price than the X-Pro3, despite having a lens built in. 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 imaging sensor is a crucial determinant 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. 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.

Fujifilm X-Pro3 and Ricoh GR IIIx sensor measures

With 26MP, the X-Pro3 offers a slightly higher resolution than the GR IIIx (24MP), but the X-Pro3 has smaller individual pixels (pixel pitch of 3.76μm versus 3.91μm for the GR IIIx). Moreover, the GR IIIx is a somewhat more recent model (by 1 year and 10 months) than the X-Pro3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The Fujifilm X-Pro3 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).

In terms of underlying technology, the X-Pro3 is build around a BSI-CMOS sensor, while the GR IIIx uses a CMOS imager. The X-Pro3 uses Fujifilm's X-Trans layout of photosites, while the GR IIIx employs the more common Bayer array.

X-Pro3 versus GR IIIx MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-Pro3 has an electronic viewfinder (3690k dots), which can be very helpful 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 Fujifilm X-Pro3 and Ricoh GR IIIx along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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-Pro3 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-Pro3 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 X-Pro3 and the GR IIIx write their files to SDXC cards. The X-Pro3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GR IIIx only has one slot. The X-Pro3 supports UHS-II cards (on both slots), while the GR IIIx can use UHS-I cards.

It is notable that the X-Pro3 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.

Studio photographers will appreciate that the Fujifilm X-Pro3 (unlike the GR IIIx) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X-Pro3 and the GR IIIx are recent models that are part of the current product line-up. The X-Pro3 replaced the earlier Fujifilm X-Pro2, while the GR IIIx followed on from the Ricoh GR II. Further information on the features and operation of the X-Pro3 and GR IIIx can be found, respectively, in the Fujifilm X-Pro3 Manual (free pdf) or the online Ricoh GR IIIx Manual.

Review summary

So what conclusions can be drawn? Is the Fujifilm X-Pro3 better than the Ricoh GR IIIx or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Fujifilm X-Pro3:

  • Better video: Provides higher definition movie capture (4K/30p 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 detailed LCD: Has a higher resolution rear screen (1620k vs 1037k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8 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 (440 versus 200) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More heavily discounted: Has been on the market for longer (launched in October 2019).

ilogo

Arguments in favor of the Ricoh GR IIIx:

  • Ready to shoot: Has an integrated lens, whereas the X-Pro3 necessitates an extra lens.
  • More compact: Is smaller (109x62mm vs 141x83mm) 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-Pro3).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Was introduced somewhat (1 year and 10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the X-Pro3 is the clear winner of the match-up (15 : 6 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.

X-Pro3 15:06 GR IIIx

How about other alternatives? Do the specifications of the Fujifilm X-Pro3 and the Ricoh GR IIIx 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 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 X-Pro3 or the GR IIIx 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Note: (+ +) 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
