Olympus E-M10 III versus Panasonic LX100

The Olympus OM-D E-M10 Mark III and the Panasonic Lumix DMC-LX100 are two digital cameras that were revealed to the public, respectively, in August 2017 and September 2014. The E-M10 III is a mirrorless interchangeable lens camera, while the LX100 is a fixed lens compact. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Panasonic provides 12.7 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 III vs Panasonic LX100

The physical size and weight of the Olympus E-M10 III and the Panasonic LX100 are illustrated 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 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 side – the E-M10 III – represents the basis for the calculations 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 Panasonic LX100 is notably smaller (26 percent) than the Olympus E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the LX100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens build in, whereas the E-M10 III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 III gets 330 shots out of its BLS-50 battery, while the LX100 can take 300 images on a single charge of its DMW-BLG10 power pack.

Any camera purchase will naturally be influenced heavily by the price. 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. 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 III vs Panasonic LX100

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 III and Panasonic LX100 sensor measures

While the two cameras under review share the same sensor size, the E-M10 III offers a higher resolution of 15.9 megapixel, compared with 12.7 MP of the LX100. This megapixel advantage translates into a 12 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 III has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.21μm for the LX100). In this context, it should be noted, however, that the E-M10 III is much more recent (by 2 years and 11 months) than the LX100, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the LX100 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).

Both the E-M10 III and the LX100 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The E-M10 III replaced the earlier Olympus E-M10 II, while the LX100 does not have a direct predecessor.

Review summary: Olympus E-M10 III vs Panasonic LX100

So what conclusions can be drawn? Is the Olympus E-M10 III better than the Panasonic LX100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

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

  • More detail: Offers more megapixels (15.9 vs 12.7MP) with a 12% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.

ilogo

Advantages of the Panasonic Lumix DMC-LX100:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 2360k dots).
  • Faster burst: Shoots at higher frequency (11 vs 8.6 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Ready to shoot: Has an integrated lens, whereas the E-M10 III necessitates an extra lens.
  • More compact: Is smaller (115x66mm vs 122x84mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the E-M10 III).
  • More heavily discounted: Has been around for much longer (launched in September 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (8 points each). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

E-M10 III 08:08 LX100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M10 III and the LX100 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
