Olympus E-M10 II versus Leica CL

The Olympus OM-D E-M10 Mark II and the Leica CL (Typ 7323) are two digital cameras that were revealed to the public, respectively, in August 2015 and November 2017. Both the E-M10 II and the CL are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M10 II) and an APS-C (CL) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Leica provides 24.1 MP. 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 Leica CL

An illustration of the physical size and weight of the Olympus E-M10 II and the Leica CL is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 the basis or 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 Leica CL is somewhat larger (3 percent) than the Olympus E-M10 II. Moreover, the CL is slightly heavier (3 percent) than the E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the CL 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-M10 II gets 320 shots out of its BLS-50 battery, while the CL can take 220 images on a single charge of its BP-DC12 power pack.

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 71 percent) than the CL, 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-M10 II vs Leica CL

The size of the imaging sensor is a crucial determinant 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 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-M10 II features a Four Thirds sensor and the Leica CL an APS-C sensor. The sensor area in the CL is 65 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-M10 II has a native 4:3 aspect ratio, while the one in the CL offers a 3:2 aspect.

Sensor size

With 24.1MP, the CL offers a higher resolution than the E-M10 II (15.9MP), but the CL nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.76μm for the E-M10 II) due to its larger sensor. Moreover, the CL is a much more recent model (by 2 years and 2 months) than the E-M10 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the CL provides a better video resolution than the E-M10 II. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60p.

Feature comparison: Olympus E-M10 II vs Leica CL

Apart from body and sensor, cameras can and do differ across a range of features. The E-M10 II and the CL 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 table below summarizes some of the other core capabilities of the Olympus E-M10 II and Leica CL in connection with corresponding information for a sample of similar cameras.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 II or the CL. 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. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
