Body comparison

An illustration of the physical size and weight of the Olympus E-M5 II and the Sony A58 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 measures are rounded to the nearest millimeter.

The E-M5 II can be obtained in two different colors (black, silver), while the A58 is only available in black.

Compare E-M5 II versus A58 top
Comparison E-M5 II or A58 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is notably larger (16 percent) than the Olympus E-M5 II. Moreover, the A58 is markedly heavier (5 percent) than the E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the A58 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-M5 II gets 310 shots out of its Olympus BLN-1 battery, while the A58 can take 690 images on a single charge of its Sony NP-FM500H power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A58 was launched at a markedly lower price (by 45 percent) than the E-M5 II, which puts it into a different market segment. 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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-M5 II features a Four Thirds sensor and the Sony A58 an APS-C sensor. The sensor area in the A58 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-M5 II has a native 4:3 aspect ratio, while the one in the A58 offers a 3:2 aspect.

Olympus E-M5 II and Sony A58 sensor measures

With 19.8MP, the A58 offers a higher resolution than the E-M5 II (15.9MP), but the A58 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.76μm for the E-M5 II) due to its larger sensor. However, the E-M5 II is a somewhat more recent model (by 1 year and 11 months) than the A58, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Olympus E-M5 II are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

Unlike the A58, 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).

The Olympus OM-D E-M5 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.

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-M5 II versus A58 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance.

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-M5 II has a touchscreen, while the A58 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-M5 II 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 A58 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-M5 II 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-M5 II 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-M5 II writes its imaging data to SDXC cards, while the A58 uses SDXC or Memory Stick PRO Duo cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A58 cannot take advantage of Ultra High Speed SD cards.

It is notable that the E-M5 II offers wifi support, while the A58 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-M5 II (unlike the A58) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M5 II and the A58 have been discontinued, but can regularly be found used on ebay. The A58 was replaced by the Sony A68, while the E-M5 II was followed by the Olympus E-M5 III. Further information on the features and operation of the E-M5 II and A58 can be found, respectively, in the Olympus E-M5 II Manual (free pdf) or the online Sony A58 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-M5 II or the Sony A58 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Olympus OM-D E-M5 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.57x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
  • 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 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (124x85mm vs 129x95mm) and thus needs less room in the bag.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More modern: Is somewhat more recent (announced 1 year and 11 months after the A58).

ilogo

Advantages of the Sony Alpha SLT-A58:

  • More detail: Has more megapixels (19.8 vs 15.9MP), which boosts linear resolution by 14%.
  • Longer lasting: Gets more shots (690 versus 310) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 II is the clear winner of the match-up (20 : 5 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-M5 II 20:05 A58

How about other alternatives? Do the specifications of the Olympus E-M5 II and the Sony A58 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the E-M5 II and the A58 in practical situations. 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.

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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
