Olympus E-5 versus Panasonic GH5

The Olympus E-5 and the Panasonic Lumix DC-GH5 are two digital cameras that were revealed to the public, respectively, in September 2010 and January 2017. The E-5 is a DSLR, while the GH5 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixel, whereas the Panasonic provides 20.2 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: Olympus E-5 vs Panasonic GH5

An illustration of the physical size and weight of the Olympus E-5 and the Panasonic GH5 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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-5 – 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 GH5 is notably smaller (18 percent) than the Olympus E-5. Moreover, the GH5 is markedly lighter (17 percent) than the E-5. 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Four Thirds Lens Catalog (E-5) and the Micro Four Thirds Lens Catalog (GH5). Mirrorless cameras, such as the GH5, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the E-5 gets 750 shots out of its BLM-5 battery, while the GH5 can take 410 images on a single charge of its DMW-BLF19 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 E-5 was launched at a somewhat lower price (by 15 percent) than the GH5, 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: Olympus E-5 vs Panasonic GH5

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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.

Olympus E-5 and Panasonic GH5 sensor measures
Sensor size

While the two cameras under review share the same sensor size, the GH5 offers a higher resolution of 20.2 megapixel, compared with 12.2 MP of the E-5. This megapixel advantage translates into a 29 percent gain in linear resolution. On the other hand, these sensor specs imply that the GH5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.29μm for the E-5). However, it should be noted that the GH5 is much more recent (by 6 years and 3 months) than the E-5, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the GH5 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the GH5 offers substantially better image quality than the E-5 (overall score 21 points higher). The advantage is based on 2.3 bits higher color depth, 2.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GH5 provides a better video resolution than the E-5. It can shoot movie footage at 4K/60p, while the Olympus is limited to 720/30p.

Feature comparison: Olympus E-5 vs Panasonic GH5

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH5 has an electronic viewfinder (3680k dots), while the E-5 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Olympus E-5 and Panasonic GH5 in connection with corresponding information for a sample of similar cameras.

  • Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (139x98mm vs 142x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 148g or 17 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More modern: Reflects 6 years and 3 months of technical progress since the E-5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GH5 is the clear winner of the contest (16 : 7 points). 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.

E-5 07:16 GH5

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-5 or the GH5. 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 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
