Olympus E-M1 versus Olympus E-M10 II
The Olympus OM-D E-M1 and the Olympus OM-D E-M10 Mark II are two digital cameras that were announced, respectively, in September 2013 and August 2015. Both the E-M1 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-M1 vs Olympus E-M10 II
An illustration of the physical size and weight of the Olympus E-M1 and the Olympus E-M10 II is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 side – the E-M1 – represents the basis for the calculations 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 (18 percent) than the Olympus E-M1. Moreover, the E-M10 II is markedly lighter (22 percent) than the E-M1. It is worth mentioning in this context that the E-M1 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 43 percent) than the E-M1, 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-M1 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 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.
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-M1 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 a somewhat more recent model (by 1 year and 11 months) than the E-M1, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
For most 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 image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M10 II provides a faster frame rate than the E-M1. It can shoot movie footage at 1080/60p, while the E-M1 is limited to 1080/30p.
Feature comparison: Olympus E-M1 vs Olympus E-M10 II
Beyond body and sensor, cameras can and do differ across a range of features. The E-M1 and the E-M10 II are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The adjacent table lists some of the other core features of the Olympus E-M1 and Olympus E-M10 II along with similar information for a selection of comparators.

Both the E-M1 and the E-M10 II have been discontinued, but can regularly be found used on eBay. The E-M1 was replaced by the Olympus E-M1 II, while the E-M10 II was followed by the Olympus E-M10 III.
Review summary: Olympus E-M1 vs Olympus E-M10 II
So how do things add up? Which of the two cameras – the Olympus E-M1 or the Olympus E-M10 II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus OM-D E-M1:
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been on the market for longer (launched in September 2013).
Arguments in favor of the Olympus OM-D E-M10 Mark II:
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- More compact: Is smaller (120x83mm vs 130x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 107g or 22 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 11 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 II emerges as the winner of the match-up (6 : 4 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M1 and the E-M10 II 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
