Leica CL vs Olympus E-M10 III
The Leica CL (Typ 7323) and the Olympus OM-D E-M10 Mark III are two digital cameras that were revealed to the public, respectively, in November 2017 and August 2017. Both the CL and the E-M10 III are mirrorless interchangeable lens cameras that are based on an APS-C (CL) and a Four Thirds (E-M10 III) sensor. The Leica has a resolution of 24.1 megapixels, whereas the Olympus provides 15.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Leica CL (Typ 7323) and the Olympus OM-D E-M10 Mark III? 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.
An illustration of the physical size and weight of the Leica CL and the Olympus E-M10 III is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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.
The E-M10 III can be obtained in two different colors (black, silver), while the CL is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica CL and the Olympus E-M10 III are of equal size. However, the E-M10 III is slightly heavier (2 percent) than the CL. In this context, it is worth noting that neither the CL nor the E-M10 III 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 III was launched at a markedly lower price (by 77 percent) than the CL, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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 Leica CL features an APS-C sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the CL has a native 3:2 aspect ratio, while the one in the E-M10 III offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24.1MP, the CL offers a higher resolution than the E-M10 III (15.9MP), but the CL nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.76μm for the E-M10 III) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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.
The resolution advantage of the Leica CL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the CL for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Olympus E-M10 III are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Leica CL (Typ 7323) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Olympus OM-D E-M10 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The CL and the E-M10 III 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 following table reports on some other key feature differences and similarities of the Leica CL, the Olympus E-M10 III, and comparable cameras.

|17.||Olympus E-M10 II||2360||n||3.0||1040||tilting||Y||1/4000s||8.0||Y||Y|
One feature that is present on the CL, but is missing on the E-M10 III is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Leica CL and the Olympus E-M10 III both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the CL and the E-M10 III write their files to SDXC cards. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.
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 Leica CL (Typ 7323) and Olympus OM-D E-M10 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The CL is a recent model that features in the current product line-up of Leica. In contrast, the E-M10 III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 III was succeeded by the Olympus E-M10 IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Olympus websites.
So how do things add up? Which of the two cameras – the Leica CL or the Olympus E-M10 III – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Leica CL (Typ 7323):
- More detail: Offers more megapixels (24.1 vs 15.9MP) with a 26% higher linear resolution.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 8.6 flaps/sec) to capture the decisive moment.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
Reasons to prefer the Olympus OM-D E-M10 Mark III:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.49x).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Longer lasting: Gets more shots (330 versus 220) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
If the count of individual advantages (bullet points above) is taken as a guide, the CL emerges as the winner of the contest (9 : 6 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the CL or the E-M10 III. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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