Olympus E-M5 II versus Sony RX100 V

The Olympus OM-D E-M5 Mark II and the Sony Cyber-shot DSC-RX100 V are two digital cameras that were announced, respectively, in February 2015 and October 2016. The E-M5 II is a mirrorless interchangeable lens camera, while the RX100 V is a fixed lens compact. The cameras are based on a Four Thirds (E-M5 II) and an one-inch (RX100 V) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Sony provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Olympus E-M5 II vs Sony RX100 V

An illustration of the physical size and weight of the Olympus E-M5 II and the Sony RX100 V is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the E-M5 II – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 V is considerably smaller (44 percent) than the Olympus E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the RX100 V does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens build in, whereas the E-M5 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M5 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M5 II gets 310 shots out of its BLN-1 battery, while the RX100 V can take 220 images on a single charge of its NP-BX1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The RX100 V was launched at a lower price than the E-M5 II, despite having a lens build 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-M5 II vs Sony RX100 V

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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-M5 II features a Four Thirds sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-M5 II has a native 4:3 aspect ratio, while the one in the RX100 V offers a 3:2 aspect.

Olympus E-M5 II and Sony RX100 V sensor measures

Despite having a smaller sensor, the RX100 V offers a higher resolution of 20 megapixel, compared with 15.9 MP of the E-M5 II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.76μm for the E-M5 II). However, it should be noted that the RX100 V is a somewhat more recent model (by 1 year and 8 months) than the E-M5 II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

Unlike the RX100 V, the E-M5 II has the capacity to capture high quality composite images (40MP) 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).

E-M5 II versus RX100 V 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M5 II has a touchscreen, while the RX100 V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The E-M5 II writes its imaging data to SDXC cards, while the RX100 V uses SDXC or Memory Stick PRO Duo cards.

Both the E-M5 II and the RX100 V are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The E-M5 II replaced the earlier Olympus E-M5, while the RX100 V followed on from the Sony RX100 IV.

Review summary: Olympus E-M5 II vs Sony RX100 V

So how do things add up? Is the Olympus E-M5 II better than the Sony RX100 V or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Olympus OM-D E-M5 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More flexible LCD: Has 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.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (310 versus 220) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX100 V:

  • More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
  • Faster burst: Shoots at higher frequency (24 vs 10 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the E-M5 II necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 124x85mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the E-M5 II).
  • 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 build-in lens.
  • More modern: Was introduced somewhat (1 year and 8 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (11 points each). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

E-M5 II 11:11 RX100 V

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 handling experience and imaging performance when actually working with the E-M5 II or the RX100 V. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 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.
