Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M1X 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: Olympus E-M1X vs Ricoh GR III

An illustration of the physical size and weight of the Olympus E-M1X 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 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 E-M1X can be obtained in two different colors (black, silver), while the GR III is only available in black.

Compare E-M1X versus GR III top
Comparison E-M1X 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 (68 percent) than the Olympus E-M1X. It is worth mentioning in this context that the E-M1X is splash and dust resistant, while the GR III does not feature any corresponding weather-sealing.

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 E-M1X 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 E-M1X and their specifications in the Micro Four Thirds Lens Catalog.

As can be seen in the images above, the E-M1X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The battery packs of both cameras can be charged via USB, 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 III was launched at a lower price than the E-M1X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus E-M1X vs Ricoh GR III

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M1X features a Four Thirds sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-M1X has a native 4:3 aspect ratio, while the one in the GR III offers a 3:2 aspect.

Olympus E-M1X and Ricoh GR III sensor measures

With 24MP, the GR III offers a higher resolution than the E-M1X (20.2MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the E-M1X) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 resolution advantage of the Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III 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 Olympus E-M1X are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.

Unlike the GR III, the E-M1X has the capacity to capture high quality composite images (80MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus OM-D E-M1X has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).

E-M1X versus GR III MP

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

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M1X provides a higher video resolution than the GR III. It can shoot video footage at 4K/30p, while the Ricoh is limited to 1080/60p.

 

Feature comparison: Olympus E-M1X vs Ricoh GR III

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M1X 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 adjacent table lists some of the other core features of the Olympus E-M1X and Ricoh GR III along with similar information for a selection of comparators.

The E-M1X 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 E-M1X 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 Olympus E-M1X 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 E-M1X and the GR III write their files to SDXC cards. The E-M1X features dual card slots, which can be very useful in case a memory card fails. In contrast, the GR III only has one slot. The E-M1X supports UHS-II cards (on both slots), while the GR III can use UHS-I cards.

 

Connectivity comparison: Olympus E-M1X vs Ricoh GR III

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.

It is notable that the E-M1X 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.

Studio photographers will appreciate that the Olympus E-M1X (unlike the GR III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M1X and the GR III are recent models that are part of the current product line-up. The GR III replaced the earlier Ricoh GR II, while the E-M1X does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Ricoh websites.


Review summary: Olympus E-M1X vs Ricoh GR III

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-M1X and the Ricoh GR III? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Ricoh GR III:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Ready to shoot: Has an integrated lens, whereas the E-M1X necessitates an extra lens.
  • More compact: Is smaller (109x62mm vs 144x147mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-M1X).
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M1X is the clear winner of the match-up (17 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.

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

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
