Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL7 and the Panasonic Lumix DMC-GH2? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Olympus E-PL7 and the Panasonic GH2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH2 is considerably larger (45 percent) than the Olympus E-PL7. Moreover, the GH2 is markedly heavier (24 percent) than the E-PL7. In this context, it is worth noting that neither the E-PL7 nor the GH2 are weather-sealed.
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 compare the optics available 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.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-PL7 was launched at a markedly lower price (by 33 percent) than the GH2, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixels. This similarity in sensor specs implies that both the E-PL7 and the GH2 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-PL7 is much more recent (by 3 years and 11 months) than the GH2, and its sensor will have benefitted from technological advances during this time.
The Olympus PEN E-PL7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GH2 are ISO 160 to ISO 12800 (no boost).
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. Of the two cameras under review, the E-PL7 provides substantially higher image quality than the GH2, with an overall score that is 12 points higher. This advantage is based on 1.5 bits higher color depth, 1.1 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. 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 GH2 provides a faster frame rate than the E-PL7. It can shoot movie footage at 1080/60i, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH2 has an electronic viewfinder (1534k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The table below summarizes some of the other core capabilities of the Olympus E-PL7 and Panasonic GH2 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-PL7 and the GH2 is in-body image stabilization (IBIS). The E-PL7 reduces the risk of handshake-induced blur with all attached lenses, while the GH2 offers no blur reduction with lenses that themselves do not provide optical image stabilization.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The Olympus E-PL7 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the E-PL7 and the GH2 write their files to SDXC cards. The E-PL7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH2 cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus PEN E-PL7 and Panasonic Lumix DMC-GH2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL7 offers wifi support, while the GH2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the E-PL7 and the GH2 have been discontinued, but can regularly be found used on eBay. The GH2 was replaced by the Panasonic GH3, while the E-PL7 was followed by the Olympus E-PL8. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.
So what is the bottom line? Which of the two cameras – the Olympus E-PL7 or the Panasonic GH2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus PEN E-PL7:
- Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.5 bits more color depth).

- More heavily discounted: Has been around for much longer (launched in September 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the E-PL7 is the clear winner of the match-up (15 : 6 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 before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Olympus E-PL7 and the Panasonic GH2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
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 shooting experience and imaging performance when actually working with the E-PL7 or the GH2. 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 ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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.
