Olympus E-M10 II versus Panasonic G85

The Olympus OM-D E-M10 Mark II and the Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) are two digital cameras that were officially introduced, respectively, in August 2015 and September 2016. Both the E-M10 II 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.

Body comparison

The physical size and weight of the Olympus E-M10 II and the Panasonic G85 are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the E-M10 II – represents 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 G85 is notably larger (14 percent) than the Olympus E-M10 II. Moreover, the G85 is markedly heavier (29 percent) than the E-M10 II. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. It is noteworthy in this context that the G85 is splash and dust-proof, while the E-M10 II 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 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 E-M10 II was launched at a somewhat lower price (by 11 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.

Sensor comparison

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. 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 are more costly to manufacture and tent to 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.

Sensor size

While the two cameras under review share the same sensor size, the E-M10 II 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-M10 II 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 a somewhat more recent model (by 1 year) than the E-M10 II, and its sensor might 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.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. 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 II. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-M10 II and the G85 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of (2360k dots). The table below summarizes some of the other core capabilities of the Olympus E-M10 II and Panasonic G85 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, 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-M10 II has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III.

Summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M10 II or the Panasonic G85 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of the Olympus OM-D E-M10 Mark II:

  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • More compact: Is smaller (120x83mm vs 128x89mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 115g or 23 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in August 2015).

logo checkmark

Reasons to prefer the Panasonic Lumix DMC-G85:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 II comes out slightly ahead of the G85 (5 : 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M10 II and the G85 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, 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 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.
