Panasonic G80 versus Olympus E-M5 II

The Panasonic Lumix DMC-G80 (called Panasonic G85 in some regions) and the Olympus OM-D E-M5 Mark II are two digital cameras that were announced, respectively, in September 2016 and February 2015. Both the G80 and the E-M5 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 G80 vs Olympus E-M5 II

The side-by-side display below illustrates the physical size and weight of the Panasonic G80 and the Olympus E-M5 II. 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. 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 side – the G80 – 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 Olympus E-M5 II is notably smaller (7 percent) than the Panasonic G80. Moreover, the E-M5 II is markedly lighter (7 percent) than the G80. 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.

Concerning battery life, the G80 gets 330 shots out of its DMW-BLC12 battery, while the E-M5 II can take 310 images on a single charge of its BLN-1 power pack.

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 G80 was launched at a somewhat lower price (by 18 percent) than the E-M5 II, 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: Panasonic G80 vs Olympus E-M5 II

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 tend 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic G80 and Olympus E-M5 II sensor measures

While the two cameras under review share the same sensor size, the E-M5 II offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the G80. This megapixel advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M5 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 G80). Moreover, it should be noted, that the G80 is a somewhat more recent model (by 1 year and 7 months) than the E-M5 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 the G80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the G80, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

G80 versus E-M5 II MP

Consistent information on actual sensor performance is available from DXO Mark for many 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G80 provides a higher video resolution than the E-M5 II. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.

 

Feature comparison: Panasonic G80 vs Olympus E-M5 II

Apart from body and sensor, cameras can and do differ across a variety of features. The G80 and the E-M5 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 table below summarizes some of the other core capabilities of the Panasonic G80 and Olympus E-M5 II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The G80 has one, while the E-M5 II does not. While the build-in flash of the G80 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G80 and the E-M5 II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The E-M5 II replaced the earlier Olympus E-M5, while the G80 followed on from the Panasonic G7.

Review summary: Panasonic G80 vs Olympus E-M5 II

So what is the bottom line? Which of the two cameras – the Panasonic G80 or the Olympus E-M5 II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Panasonic Lumix DMC-G80:

  • 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 1080/60p).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (18 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 7 months after the E-M5 II).

ilogo

Reasons to prefer the Olympus OM-D E-M5 Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (5 points each). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G80 05:05 E-M5 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G80 or the E-M5 II. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
