Panasonic GM5 versus Olympus E-M10 II
The Panasonic Lumix DMC-GM5 and the Olympus OM-D E-M10 Mark II are two digital cameras that were announced, respectively, in September 2014 and August 2015. Both the GM5 and the E-M10 II are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Panasonic has a resolution of 15.8 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: Panasonic GM5 vs Olympus E-M10 II
The side-by-side display below illustrates the physical size and weight of the Panasonic GM5 and the Olympus E-M10 II. Three successive views from the front, the top, and the rear 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 – the GM5 – 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 considerably larger (68 percent) than the Panasonic GM5. Moreover, the E-M10 II is substantially heavier (85 percent) than the GM5. In this context, it is worth noting that neither the GM5 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
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. The GM5 was somewhat cheaper (by 6 percent) than the E-M10 II at launch, but both cameras fall into the same price category. 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: Panasonic GM5 vs Olympus E-M10 II
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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.
While the two cameras under review share the same sensor size, the E-M10 II offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the GM5. This megapixel advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.77μm for the GM5). However, it should be noted that the E-M10 II is a somewhat more recent model (by 11 months) than the GM5, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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"). Of the two cameras under consideration, the E-M10 II has a markedly higher DXO score than the GM5 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.8 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).
Feature comparison: Panasonic GM5 vs Olympus E-M10 II
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 II offers a substantially higher resolution than the one in the GM5 (2360k vs 1166k dots).

Review summary: Panasonic GM5 vs Olympus E-M10 II
So how do things add up? Which of the two cameras – the Panasonic GM5 or the Olympus E-M10 II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Panasonic Lumix DMC-GM5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (99x60mm vs 120x83mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 179g or 46 percent) and hence easier to carry around.
- More heavily discounted: Has been on the market for longer (launched in September 2014).
Advantages of the Olympus OM-D E-M10 Mark II:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1166k dots).
- 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.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 5.8 flaps/sec) to capture the decisive moment.
- 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 modern: Was introduced somewhat (11 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 II is the clear winner of the contest (12 : 4 points). 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.
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 GM5 and the E-M10 II in practical situations. 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 why expert reviews are important.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
