Body comparison: Olympus E-M1 vs Panasonic GX800

The side-by-side display below illustrates the physical size and weight of the Olympus E-M1 and the Panasonic GX800. 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.

The E-M1 can be obtained in two different colors (black, silver), while the GX800 is available in three color-versions (black, silver, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX800 is considerably smaller (43 percent) than the Olympus E-M1. Moreover, the GX800 is substantially lighter (46 percent) than the E-M1. It is worth mentioning in this context that the E-M1 is splash and dust resistant, while the GX800 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-M1 gets 350 shots out of its BLN-1 battery, while the GX800 can take 210 images on a single charge of its DMW-BLH7 power pack.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GX800 was launched at a markedly lower price (by 61 percent) than the E-M1, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus E-M1 vs Panasonic GX800

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. 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 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-M1 and Panasonic GX800 sensor measures

While the two cameras under review share the same sensor size, the E-M1 offers a slightly higher resolution of 15.9 megapixels, compared with 15.8 MP of the GX800. This megapixels advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M1 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 GX800). Moreover, it should be noted that the GX800 is much more recent (by 3 years and 3 months) than the E-M1, and its sensor will 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The E-M1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Olympus OM-D E-M1 has a native sensitivity range from ISO 100 to ISO 25600 The corresponding ISO settings for the Panasonic Lumix DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600..

E-M1 versus GX800 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX800 provides a better video resolution than the E-M1. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/30p.

 

Feature comparison: Olympus E-M1 vs Panasonic GX800

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M1 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Olympus E-M1, the Panasonic GX800, and comparable cameras.

One feature that differentiates the E-M1 and the GX800 is in-body image stabilization (IBIS). The E-M1 reduces the risk of handshake-induced blur with all attached lenses, while the GX800 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The GX800 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-M1 does not have a selfie-screen.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX800 features an 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).

Concerning the storage of imaging data, both the E-M1 and the GX800 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Olympus E-M1 vs Panasonic GX800

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-M1 and Panasonic Lumix DMC-GX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M1 has a hotshoe, while the GX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Olympus E-M1 (unlike the GX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The GX800 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-M1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M1 was succeeded by the Olympus E-M1 II.


Review summary: Olympus E-M1 vs Panasonic GX800

So what is the bottom line? Is the Olympus E-M1 better than the Panasonic GX800 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX800:

  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (107x65mm vs 130x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 228g or 46 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 introduced into a lower priced category (61 percent cheaper at launch).
  • More modern: Reflects 3 years and 3 months of technical progress since the E-M1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M1 emerges as the winner of the contest (11 : 9 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.

E-M1 11:09 GX800

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-M1 or the GX800. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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

The review scores listed above should be treated 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.
