Leica C-LUX vs Olympus E-M5
The Leica C-LUX and the Olympus OM-D E-M5 are two digital cameras that were officially introduced, respectively, in June 2018 and February 2012. The C-LUX is a fixed lens compact, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (C-LUX) and a Four Thirds (E-M5) sensor. The Leica has a resolution of 20 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 C-LUX and the Olympus OM-D E-M5? 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.
The side-by-side display below illustrates the physical size and weight of the Leica C-LUX and the Olympus E-M5. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The C-LUX can be obtained in two different colors (gold, blue), while the E-M5 is also available in two color-versions, but different ones (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 is considerably larger (43 percent) than the Leica C-LUX. It is noteworthy in this context that the E-M5 is splash and dust-proof, while the C-LUX does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the C-LUX has a lens built in, whereas the E-M5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M5 and their specifications in the Micro Four Thirds Lens Catalog.
The power pack in the C-LUX can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 C-LUX was launched at a lower price than the E-M5, despite having a lens built in. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.
Of the two cameras under consideration, the Leica C-LUX features an one-inch sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the C-LUX has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the Leica C-LUX offers a higher resolution of 20 megapixels, compared with 15.9 MP of the Olympus E-M5. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.76μm for the E-M5). However, it should be noted that the C-LUX is much more recent (by 6 years and 4 months) than the E-M5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Leica C-LUX implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the C-LUX for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M5 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 C-LUX has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 C-LUX provides a higher video resolution than the E-M5. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the C-LUX offers a substantially higher resolution than the one in the E-M5 (2330k vs 1440k dots). The adjacent table lists some of the other core features of the Leica C-LUX and Olympus E-M5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The C-LUX has one, while the E-M5 does not. While the built-in flash of the C-LUX is not very powerful, it can at times be useful as a fill-in light.
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, the C-LUX is one of those camera that have an additional 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 C-LUX has 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 C-LUX and the E-M5 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 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 C-LUX and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the C-LUX offers wifi support, while the E-M5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The C-LUX is a recent model that features in the current product line-up of Leica. In contrast, the E-M5 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M5 was succeeded by the Olympus E-M5 II. 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 what conclusions can be drawn? Is the Leica C-LUX better than the Olympus E-M5 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Leica C-LUX:
- More detail: Offers more megapixels (20 vs 15.9MP) with a 14% higher linear resolution.

- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in February 2012).
If the count of relative strengths (bullet points above) is taken as a measure, the C-LUX is the clear winner of the match-up (15 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Leica C-LUX and the Olympus E-M5 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
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 C-LUX or the E-M5. 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 ratings of the cameras as published by some of the major 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
