Olympus E-M10 vs Panasonic G85
The Olympus OM-D E-M10 and the Panasonic Lumix DMC-G85 (labelled Panasonic G80 in some countries) are two digital cameras that were revealed to the public, respectively, in January 2014 and September 2016. Both the E-M10 and the G85 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Panasonic provides 15.8 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 Olympus OM-D E-M10 and the Panasonic Lumix DMC-G85? 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.
An illustration of the physical size and weight of the Olympus E-M10 and the Panasonic G85 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 width, height and depth measures are rounded to the nearest millimeter.
The E-M10 can be obtained in two different colors (black, silver), while the G85 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G85 is notably larger (17 percent) than the Olympus E-M10. Moreover, the G85 is markedly heavier (28 percent) than the E-M10. It is noteworthy in this context that the G85 is splash and dust-proof, while the E-M10 does not feature any corresponding weather-sealing.
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 compare the optics available 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.
Concerning battery life, the E-M10 gets 320 shots out of its BLS-5 battery, while the G85 can take 330 images on a single charge of its DMW-BLC12 power pack.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 was launched at a somewhat lower price (by 22 percent) than the G85, which makes it more attractive for photographers on a tight budget. 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.
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. 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 more expensive and lead to bigger and heavier cameras 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 offers a slightly higher resolution of 15.9 megapixels, compared with 15.8 MP of the G85. This megapixels advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 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 G85). Moreover, it should be noted that the G85 is much more recent (by 2 years and 7 months) than the E-M10, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual 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.
The Olympus OM-D E-M10 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Panasonic Lumix DMC-G85 offers exactly the same ISO settings.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 G85 provides a better video resolution than the E-M10. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the G85 offers a substantially higher resolution than the one in the E-M10 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M10, the Panasonic G85, and comparable cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
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 G85 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 Olympus E-M10 and the Panasonic G85 both have 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 E-M10 and the G85 write their files to SDXC cards. The G85 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-M10 can use UHS-I cards (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 Olympus OM-D E-M10 and Panasonic Lumix DMC-G85 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G85 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 does not feature such a mic input.
Both the E-M10 and the G85 have been discontinued, but can regularly be found used on ebay. The E-M10 was replaced by the Olympus E-M10 II, while the G85 was followed by the Panasonic G95. Further information on the features and operation of the E-M10 and G85 can be found, respectively, in the Olympus E-M10 Manual (free pdf) or the online Panasonic G85 Manual.
So how do things add up? Which of the two cameras – the Olympus E-M10 or the Panasonic G85 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus OM-D E-M10:
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- More compact: Is smaller (119x82mm vs 128x89mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 109g or 22 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced segment (22 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in January 2014).
Advantages of the Panasonic Lumix DMC-G85:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.58x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 2 years and 7 months of technical progress since the E-M10 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G85 is the clear winner of the contest (11 : 5 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Olympus E-M10 and the Panasonic G85 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the E-M10 and the G85 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 provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
