Olympus E-M5 versus Olympus E-M10 II
The Olympus OM-D E-M5 and the Olympus OM-D E-M10 Mark II are two digital cameras that were revealed to the public, respectively, in February 2012 and August 2015. Both the E-M5 and the E-M10 II are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.9 megapixel. 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 vs Olympus E-M10 II
The side-by-side display below illustrates the physical size and weight of the Olympus E-M5 and the Olympus E-M10 II. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – represents 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 Olympus E-M10 II is notably smaller (8 percent) than the Olympus E-M5. Moreover, the E-M10 II is markedly lighter (8 percent) than the E-M5. It is worth mentioning in this context that the E-M5 is splash and dust resistant, while the E-M10 II 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 II was launched at a markedly lower price (by 38 percent) than the E-M5, 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. 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 Olympus E-M10 II
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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixel. This similarity in sensor specs implies that both the E-M5 and the E-M10 II have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-M10 II is much more recent (by 3 years and 6 months) than the E-M5, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M10 II provides a faster frame rate than the E-M5. It can shoot movie footage at 1080/60p, while the E-M5 is limited to 1080/60i.
Feature comparison: Olympus E-M5 vs Olympus E-M10 II
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 II offers a substantially higher resolution than the one in the E-M5 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M5, the Olympus E-M10 II, and comparable cameras.

Both the E-M5 and the E-M10 II have been discontinued, but can regularly be found used on eBay. The E-M5 was replaced by the Olympus E-M5 II, while the E-M10 II was followed by the Olympus E-M10 III.
Review summary: Olympus E-M5 vs Olympus E-M10 II
So what conclusions can be drawn? Which of the two cameras – the Olympus E-M5 or the Olympus E-M10 II – has the upper hand? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (360 versus 320) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been available for much longer (launched in February 2012).
Arguments in favor of the Olympus OM-D E-M10 Mark II:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 610k dots).
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More modern: Reflects 3 years and 6 months of technical progress since the E-M5 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 II emerges as the winner of the match-up (7 : 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.
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 or the E-M10 II. 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).

The above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
