Leica CL versus Olympus E-M10 II

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

An illustration of the physical size and weight of the Leica CL and the Olympus E-M10 II is provided 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the CL – 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 Olympus E-M10 II is somewhat smaller (3 percent) than the Leica CL. Moreover, the E-M10 II is slightly lighter (3 percent) than the CL. In this context, it is worth noting that neither the CL nor the E-M10 II 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 CL gets 220 shots out of its BP-DC12 battery, while the E-M10 II can take 320 images on a single charge of its BLS-50 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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: Leica CL vs Olympus E-M10 II

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 more expensive and 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 II a Four Thirds sensor. The sensor area in the E-M10 II 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 II offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Leica CL and Olympus E-M10 II sensor measures

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 somewhat more recent model (by 2 years and 2 months) than the E-M10 II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 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 CL provides a higher video resolution than the E-M10 II. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.

 

Feature comparison: Leica CL vs Olympus E-M10 II

Apart from body and sensor, cameras can and do differ across a range of features. The CL 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 Leica CL and Olympus E-M10 II along with similar information for a selection of comparators.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the CL features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The CL is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M10 II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III.

Review summary: Leica CL vs Olympus E-M10 II

So what is the bottom line? Which of the two cameras – the Leica CL or the Olympus E-M10 II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

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 a larger and more technologically advanced imaging sensor.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Reflects 2 years and 2 months of technical progress since the E-M10 II launch.

ilogo

Advantages of the Olympus OM-D E-M10 Mark II:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Longer lasting: Gets more shots (320 versus 220) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in August 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the CL emerges as the winner of the contest (9 : 6 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.

CL 09:06 E-M10 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the CL and the E-M10 II in practical situations. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known 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.
