Body comparison

An illustration of the physical size and weight of the Olympus E-M1 II and the Sony A5000 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 size dimensions are rounded to the nearest millimeter.

The A5000 can be obtained in three different colors (black, silver, white), while the E-M1 II is only available in black.

Size Olympus E-M1 II vs Sony A5000
Compare E-M1 II versus A5000 top
Comparison E-M1 II or A5000 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A5000 is considerably smaller (43 percent) than the Olympus E-M1 II. Moreover, the A5000 is substantially lighter (53 percent) than the E-M1 II. It is worth mentioning in this context that the E-M1 II is splash and dust resistant, while the A5000 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (E-M1 II) and the Sony E-Mount Lens Catalog (A5000). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the E-M1 II gets 440 shots out of its Olympus BLH-1 battery, while the A5000 can take 420 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A5000 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 A5000 was launched at a markedly lower price (by 78 percent) than the E-M1 II, which puts it into a different market segment. 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.

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. 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-M1 II features a Four Thirds sensor and the Sony A5000 an APS-C sensor. The sensor area in the A5000 is 59 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-M1 II has a native 4:3 aspect ratio, while the one in the A5000 offers a 3:2 aspect.

Olympus E-M1 II and Sony A5000 sensor measures

Despite having a smaller sensor, the Olympus E-M1 II offers a higher resolution of 20.2 megapixels, compared with 19.8 MP of the Sony A5000. 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 4.25μm for the A5000). However, it should be noted that the E-M1 II is much more recent (by 2 years and 8 months) than the A5000, 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 the E-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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

Unlike the A5000, the E-M1 II has the capacity to capture high quality composite images (50MP) 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 II 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 Alpha A5000 are ISO 100 to ISO 16000 (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.

E-M1 II versus A5000 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 feature that differentiates the E-M1 II and the A5000 is in-body image stabilization (IBIS). The E-M1 II reduces the risk of handshake-induced blur with all attached lenses, while the A5000 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 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-M1 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-M1 II writes its imaging data to SDXC cards, while the A5000 uses SDXC or Memory Stick PRO Duo cards. The E-M1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the A5000 only has one slot. The E-M1 II supports UHS-II cards (on its first slot), while the A5000 can use UHS-I cards.

It is notable that the E-M1 II has a hotshoe, while the A5000 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Olympus E-M1 II (unlike the A5000) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M1 II and the A5000 have been discontinued, but can regularly be found used on ebay. The A5000 was replaced by the Sony A5100, while the E-M1 II was followed by the Olympus E-M1 III. Further information on the features and operation of the E-M1 II and A5000 can be found, respectively, in the Olympus E-M1 II Manual (free pdf) or the online Sony A5000 Manual.

ilogo

Arguments in favor of the Sony Alpha A5000:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (110x63mm vs 134x91mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 305g or 53 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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 into a lower priced category (78 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in January 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the E-M1 II is the clear winner of the match-up (22 : 8 points). 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. 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-M1 II 22:08 A5000

How about other alternatives? Do the specifications of the Olympus E-M1 II and the Sony A5000 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-M1 II and the A5000 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
