Panasonic G85 versus Olympus E-M10 II

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

Body comparison

An illustration of the physical size and weight of the Panasonic G85 and the Olympus E-M10 II is provided 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 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 G85 – 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 notably smaller (13 percent) than the Panasonic G85. Moreover, the E-M10 II is markedly lighter (23 percent) than the G85. Cameras that are aimed at professionals or semi-pros tend to be a bit bulkier in order to give them the necessary environmental and shock resistance. It is worth mentioning in this context that the G85 is splash and dust resistant, 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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.

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). In this context, it should be noted, however, 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 at least partly compensate for the smaller pixel size. 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

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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G85 provides a higher video resolution than the E-M10 II. It can shoot video 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 G85 and the E-M10 II 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 following table reports on some other key feature differences and similarities of the Panasonic G85, the Olympus E-M10 II, and comparable cameras.

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 Panasonic G85 or the Olympus E-M10 II – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Advantages of 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 weather sealed to enable shooting in dusty or wet environments.
  • More modern: Is somewhat more recent (announced 1 year after the E-M10 II).

logo checkmark

Reasons to prefer the Olympus OM-D E-M10 Mark II:

  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • More compact: Is smaller (120x83mm vs 128x89mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 115g or 23 percent) and is thus easier to take along.
  • More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 II comes out slightly ahead of the G85 (5 : 4 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.

G85 04:05 E-M10 II

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 G85 or the E-M10 II 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 full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
