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 announced, 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

An illustration of the physical size and weight of the Olympus E-M10 III and the Panasonic LX100 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 III – 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 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.

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. 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 sensor inside a digital camera is one of the key determinants 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. 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
Sensor size

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.

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.
  • 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 count of relative strengths (bullet points above) is taken as a measure, the E-M10 III comes out slightly ahead of the LX100 (8 : 7 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.

E-M10 III 08:07 LX100

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 III or the LX100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. 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 above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
