Olympus E-M10 II versus Olympus E-M10

The Olympus OM-D E-M10 Mark II and the Olympus OM-D E-M10 are two digital cameras that were revealed to the public, respectively, in August 2015 and January 2014. Both the E-M10 II and the E-M10 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-M10 II vs Olympus E-M10

The physical size and weight of the Olympus E-M10 II and the Olympus E-M10 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 – the E-M10 II – 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 is somewhat smaller (2 percent) than the Olympus E-M10 II. However, the E-M10 is slightly heavier (2 percent) than the E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the E-M10 are weather-sealed.

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

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-M10 was launched at a somewhat lower price (by 13 percent) than the E-M10 II, which makes it more attractive for photographers on a tight budget. 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-M10 II vs Olympus E-M10

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. 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 associated with larger, more expensive camera bodies 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.

Olympus E-M10 II and Olympus E-M10 sensor measures

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-M10 II and the E-M10 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 6 months) than the E-M10, 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.

E-M10 II versus E-M10 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 have a sensor with sufficiently fast read-out times for moving pictures, but the E-M10 II provides a higher frame rate than the E-M10. It can shoot video footage at 1080/60p, while the E-M10 is limited to 1080/30p.

 

Feature comparison: Olympus E-M10 II vs Olympus E-M10

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration 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-M10 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus E-M10 II and Olympus E-M10 in connection with corresponding information for a sample of similar cameras.

Both the E-M10 II and the E-M10 have been discontinued, but can regularly be found used on eBay. The E-M10 was replaced by the Olympus E-M10 II, while the E-M10 II was followed by the Olympus E-M10 III.

Review summary: Olympus E-M10 II vs Olympus E-M10

So how do things add up? Is the Olympus E-M10 II better than the Olympus E-M10 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Olympus OM-D E-M10 Mark II:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More modern: Is somewhat more recent (announced 1 year and 6 months after the E-M10).


Advantages of the Olympus OM-D E-M10:

  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 II comes out slightly ahead of the E-M10 (3 : 2 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.

E-M10 II 03:02 E-M10

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-M10 II or the E-M10 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
