Body comparison

The side-by-side display below illustrates the physical size and weight of the OM System OM-5 and the Ricoh GR II. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The OM-5 can be obtained in two different colors (black, silver), while the GR II is only available in black.

Comparison OM-5 or GR II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR II is considerably smaller (31 percent) than the OM System OM-5. It is worth mentioning in this context that the OM-5 is splash and dust resistant, while the GR II does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR II has a lens built in, whereas the OM-5 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 OM-5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the OM-5 gets 310 shots out of its OM System BLS-50 battery, while the GR II can take 320 images on a single charge of its Ricoh DB-65 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 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 II was launched at a lower price than the OM-5, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the OM System OM-5 features a Four Thirds sensor and the Ricoh GR II an APS-C sensor. The sensor area in the GR II is 64 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 OM-5 has a native 4:3 aspect ratio, while the one in the GR II offers a 3:2 aspect.

OM System OM-5 and Ricoh GR II sensor measures

Despite having a smaller sensor, the OM System OM-5 offers a higher resolution of 20.2 megapixels, compared with 16.1 MP of the Ricoh GR II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.79μm for the GR II). However, it should be noted that the OM-5 is much more recent (by 7 years and 4 months) than the GR II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 OM System OM-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the OM-5 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Ricoh GR II are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The OM-5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the GR II, the OM-5 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 OM System OM-5 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 II are ISO 100 to ISO 25600 (no boost).

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.

OM-5 versus GR II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the OM-5 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR II relies on live view and the rear LCD for framing. That said, the GR II can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the OM System OM-5, the Ricoh GR II, and comparable 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 OM-5 has a touchscreen, while the GR II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The OM-5 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 II 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 OM-5 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 OM System OM-5 and the Ricoh GR II 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 OM-5 and the GR II write their files to SDXC cards. The OM-5 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GR II can use UHS-I cards (up to 104 MB/s).

It is notable that the OM-5 has a microphone port, which is missing on the GR II. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The OM-5 is a recent model that features in the current product line-up of OM System. In contrast, the GR II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the GR II was succeeded by the Ricoh GR III. Further information on the features and operation of the OM-5 and GR II can be found, respectively, in the OM System OM-5 Manual (free pdf) or the online Ricoh GR II Manual.

Review summary

So what is the bottom line? Is the OM System OM-5 better than the Ricoh GR II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the OM System OM-5:

  • More detail: Offers more megapixels (20.2 vs 16.1MP) with a 10% higher linear resolution.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • 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 swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 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.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 7 years and 4 months of technical progress since the GR II launch.

ilogo

Arguments in favor of the Ricoh GR II:

  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • Ready to shoot: Has an integrated lens, whereas the OM-5 necessitates an extra lens.
  • More compact: Is smaller (117x63mm vs 125x85mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the OM-5).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in June 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the OM-5 is the clear winner of the match-up (18 : 8 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.

OM-5 18:08 GR II

How about other alternatives? Do the specifications of the OM System OM-5 and the Ricoh GR II 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the OM-5 or the GR II. 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 hands-on reviews by experts 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 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
