Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 and the Sony Alpha NEX-7? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison: Olympus E-M5 vs Sony NEX-7

The side-by-side display below illustrates the physical size and weight of the Olympus E-M5 and the Sony NEX-7. 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 E-M5 can be obtained in two different colors (black, silver), while the NEX-7 is only available in black.

Compare E-M5 versus NEX-7 top
Comparison E-M5 or NEX-7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-7 is notably smaller (26 percent) than the Olympus E-M5. Moreover, the NEX-7 is markedly lighter (6 percent) than the E-M5. It is worth mentioning in this context that the E-M5 is splash and dust resistant, while the NEX-7 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-M5) and the Sony E-Mount Lens Catalog (NEX-7). 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-M5 gets 360 shots out of its BLN-1 battery, while the NEX-7 can take 430 images on a single charge of its NP-FW50 power pack.

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

Note: Measurements and pricing do not include easily detachable parts, such as 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 E-M5 was somewhat cheaper (by 4 percent) than the NEX-7 at launch, but both cameras fall into the same price category. 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: Olympus E-M5 vs Sony NEX-7

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M5 features a Four Thirds sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 62 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 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-M5 and Sony NEX-7 sensor measures

With 24MP, the NEX-7 offers a higher resolution than the E-M5 (15.9MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 3.76μm for the E-M5) due to its larger sensor. However, the E-M5 is a somewhat more recent model (by 5 months) than the NEX-7, 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 NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-M5 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Olympus OM-D E-M5 has a native sensitivity range from ISO 200 to ISO 25600. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).

E-M5 versus NEX-7 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under consideration, the NEX-7 has a markedly higher DXO score than the E-M5 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.3 bits higher color depth, 1.1 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One feature that differentiates the E-M5 and the NEX-7 is in-body image stabilization (IBIS). The E-M5 reduces the risk of handshake-induced blur with all attached lenses, while the NEX-7 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The E-M5 writes its imaging data to SDXC cards, while the NEX-7 uses SDXC or Memory Stick PRO Duo cards. The E-M5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-7 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus E-M5 vs Sony NEX-7

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus OM-D E-M5 and Sony Alpha NEX-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-7 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M5 does not feature such a mic input.

Both the E-M5 and the NEX-7 have been discontinued, but can regularly be found used on eBay. The E-M5 was replaced by the Olympus E-M5 II, while the NEX-7 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.


Review summary: Olympus E-M5 vs Sony NEX-7

So how do things add up? Is there a clear favorite between the Olympus E-M5 and the Sony NEX-7? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

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

  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Is somewhat more recent (announced 5 months after the NEX-7).

ilogo

Advantages of the Sony Alpha NEX-7:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.58x).
  • More detailed LCD: Has a higher resolution rear screen (921k vs 610k dots).
  • More compact: Is smaller (120x67mm vs 122x89mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (430 versus 360) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More heavily discounted: Has been on the market for longer (launched in August 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the NEX-7 is the clear winner of the contest (12 : 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 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-M5 05:12 NEX-7

How about other alternatives? Do the specifications of the Olympus E-M5 and the Sony NEX-7 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-M5 or the NEX-7 perform in practice. 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: Olympus E-M5 vs Sony NEX-7

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
