Olympus E-M5 versus Panasonic G85
The Olympus OM-D E-M5 and the Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) are two digital cameras that were announced, respectively, in February 2012 and September 2016. Both the E-M5 and the G85 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Panasonic provides 15.8 MP.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M5 and the Panasonic G85. 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 use the toggle button 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-M5 – 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 G85 is somewhat larger (5 percent) than the Olympus E-M5. Moreover, the G85 is markedly heavier (19 percent) than the E-M5. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G85 was launched at a markedly lower price (by 31 percent) than the E-M5, which puts it into a different market segment. 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 sensor inside a digital camera is one of the key determinants 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 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-M5 offers a higher resolution of 15.9 megapixel, compared with 15.8 MP of the G85. This megapixel advantage translates into a 0 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.75μm versus 3.77μm for the G85). However, it should be noted that the G85 is much more recent (by 4 years and 7 months) than the E-M5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back sensor resolution, it should be mentioned that the G85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 image quality. 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 are not only capable of taking still images, but also of capturing video footage. 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-M5. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60i.
Beyond 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-M5 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus E-M5 and Panasonic G85 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The G85 is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M5 has been discontinued (but it 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.
So how do things add up? Is there a clear favorite between the Olympus E-M5 and the Olympus E-M5? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Olympus OM-D E-M5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- Less heavy: Is lighter (by 80g or 16 percent) and hence easier to carry around.
- More heavily discounted: Has been available for much longer (launched in February 2012).
Arguments in favor of the Panasonic Lumix DMC-G85:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (2360k vs 1440k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 610k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 4 years and 7 months of technical progress since the E-M5 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G85 is the clear winner of the contest (8 : 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-M5 or the G85 handle or perform in practice. 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
