Olympus E-M1 III vs Sony RX1R

The Olympus OM-D E-M1 Mark III and the Sony Cyber-shot DSC-RX1R are two enthusiast cameras that were announced, respectively, in February 2020 and June 2013. The E-M1 III is a mirrorless interchangeable lens camera, while the RX1R is a fixed lens compact. The cameras are based on a Four Thirds (E-M1 III) and a full frame (RX1R) sensor. The Olympus has a resolution of 20.2 megapixels, whereas the Sony provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Olympus E-M1 III and the Sony RX1R 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 measures are rounded to the nearest millimeter.

Compare E-M1 III versus RX1R top
Comparison E-M1 III or RX1R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R is considerably smaller (40 percent) than the Olympus E-M1 III. It is worth mentioning in this context that the E-M1 III is splash and dust resistant, while the RX1R does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R has a lens built in, whereas the E-M1 III 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-M1 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M1 III gets 420 shots out of its Olympus BLH-1 battery, while the RX1R can take 270 images on a single charge of its Sony NP-BX1 power pack. 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. 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.

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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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-M1 III features a Four Thirds sensor and the Sony RX1R a full frame sensor. The sensor area in the RX1R is 280 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-M1 III has a native 4:3 aspect ratio, while the one in the RX1R offers a 3:2 aspect.

Olympus E-M1 III and Sony RX1R sensor measures

With 24MP, the RX1R offers a higher resolution than the E-M1 III (20.2MP), but the RX1R nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 3.34μm for the E-M1 III) due to its larger sensor. However, the E-M1 III is a much more recent model (by 6 years and 7 months) than the RX1R, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 Sony RX1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-M1 III are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The E-M1 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the RX1R, the E-M1 III 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-M1 Mark III 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 Sony Cyber-shot DSC-RX1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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.

E-M1 III versus RX1R MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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").

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1R relies on live view and the rear LCD for framing. That said, the RX1R can be equipped with an optional viewfinder – the FDA-EV1MK. The table below summarizes some of the other core capabilities of the Olympus E-M1 III and Sony RX1R in connection with corresponding information for a sample of similar cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M1 III has a touchscreen, while the RX1R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-M1 III 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 RX1R 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-M1 III 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-M1 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.

The E-M1 III writes its imaging data to SDXC cards, while the RX1R uses SDXC or Memory Stick PRO Duo cards. The E-M1 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX1R only has one slot. The E-M1 III supports UHS-II cards on its first slot and UHS-I on its second one, while the RX1R cannot take advantage of Ultra High Speed SD cards.

It is notable that the E-M1 III offers wifi support, while the RX1R does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Olympus E-M1 III (unlike the RX1R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M1 III and the RX1R have been discontinued, but can regularly be found used on ebay. The RX1R was replaced by the Sony RX1R II, while the E-M1 III was followed by the OM System OM-1. Further information on the features and operation of the E-M1 III and RX1R can be found, respectively, in the Olympus E-M1 III Manual (free pdf) or the online Sony RX1R Manual.

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX1R:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
  • Ready to shoot: Has an integrated lens, whereas the E-M1 III necessitates an extra lens.
  • More compact: Is smaller (113x65mm vs 134x91mm) 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-M1 III).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More heavily discounted: Has been around for much longer (launched in June 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M1 III is the clear winner of the match-up (23 : 7 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 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.

E-M1 III 23:07 RX1R

How about other alternatives? Do the specifications of the Olympus E-M1 III and the Sony RX1R 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M1 III or the RX1R. 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 why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
