Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark II and the Panasonic Lumix DMC-GH1? 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.

Body comparison

The physical size and weight of the Olympus E-M5 II and the Panasonic GH1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The E-M5 II can be obtained in two different colors (black, silver), while the GH1 is also available in two color-versions, but different ones (black, red).

Compare E-M5 II versus GH1 top
Comparison E-M5 II or GH1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH1 is notably larger (6 percent) than the Olympus E-M5 II. However, the GH1 is markedly lighter (18 percent) than the E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the GH1 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 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.

Concerning battery life, the E-M5 II gets 310 shots out of its BLN-1 battery, while the GH1 can take 300 images on a single charge of its DMW-BLB13 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GH1 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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison

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 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. 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 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.

Olympus E-M5 II and Panasonic GH1 sensor measures

While the two cameras under review share the same sensor size, the E-M5 II offers a higher resolution of 15.9 megapixels, compared with 12 MP of the GH1. This megapixels advantage translates into a 15 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 4.33μm for the GH1). In this context, it should be noted, however, that the E-M5 II is much more recent (by 5 years and 11 months) than the GH1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Olympus E-M5 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 II for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Panasonic GH1 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.

Unlike the GH1, 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).

The Olympus OM-D E-M5 Mark II 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-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

E-M5 II versus GH1 MP

Consistent information on actual sensor performance is available from DXO Mark for many 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 review, the E-M5 II has a notably higher overall DXO score than the GH1 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.4 bits higher color depth, 0.9 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M5 II provides a higher frame rate than the GH1. It can shoot video footage at 1080/60p, while the Panasonic is limited to 1080/24p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M5 II offers a substantially higher resolution than the one in the GH1 (2360k vs 1440k dots).

One feature that differentiates the E-M5 II and the GH1 is in-body image stabilization (IBIS). The E-M5 II reduces the risk of handshake-induced blur with all attached lenses, while the GH1 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M5 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M5 II 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.

The E-M5 II writes its imaging data to SDXC cards, while the GH1 uses SDHC cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GH1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison

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 OM-D E-M5 Mark II and Panasonic Lumix DMC-GH1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 II offers wifi support, while the GH1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the GH1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The E-M5 II is a recent model that features in the current product line-up of Olympus. In contrast, the GH1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GH1 was succeeded by the Panasonic GH2. 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.


Review summary

So how do things add up? Is the Olympus E-M5 II better than the Panasonic GH1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

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

  • More detail: Offers more megapixels (15.9 vs 12MP) with a 15% higher linear resolution.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More modern: Reflects 5 years and 11 months of technical progress since the GH1 launch.

ilogo

Advantages of the Panasonic Lumix DMC-GH1:

  • Less heavy: Has a lower weight (by 84g or 18 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was released into a lower priced segment (18 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in March 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 II is the clear winner of the match-up (20 : 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 before making a camera decision. 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.

E-M5 II 20:04 GH1

How about other alternatives? Do the specifications of the Olympus E-M5 II and the Panasonic GH1 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 incomplete and does no justice, for example, to the way the E-M5 II or the GH1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted 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.
