OM System OM-1 vs Panasonic GX800

The OM System OM-1 and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were officially introduced, respectively, in February 2022 and January 2017. Both the OM-1 and the GX800 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The OM System has a resolution of 20.2 megapixels, whereas the Panasonic provides 15.8 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the OM System OM-1 and the Panasonic GX800. 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 GX800 can be obtained in three different colors (black, silver, red), while the OM-1 is only available in black.

Compare OM-1 versus GX800 top
Comparison OM-1 or GX800 rear

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 (44 percent) than the OM System OM-1. Moreover, the GX800 is substantially lighter (55 percent) than the OM-1. It is worth mentioning in this context that the OM-1 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 OM-1 gets 520 shots out of its OM System BLX-1 battery, while the GX800 can take 210 images on a single charge of its Panasonic DMW-BLH7 power pack. The power pack in the OM-1 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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

Any camera decision will obviously take relative prices into account. 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 GX800 was launched at a markedly lower price (by 75 percent) than the OM-1, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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.

OM System OM-1 and Panasonic GX800 sensor measures

While the two cameras under review share the same sensor size, the OM-1 offers a higher resolution of 20.2 megapixels, compared with 15.8 MP of the GX800. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the OM-1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the GX800). In this context, it should be noted, however, that the OM-1 is much more recent (by 5 years and 1 month) than the GX800, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the OM System OM-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the OM-1 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Panasonic GX800 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The OM-1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the GX800, the OM-1 has the capacity to capture high quality composite images (80MP) 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 OM System OM-1 has a native sensitivity range from ISO 80 to ISO 25600, which can be extended to ISO 80-102400. 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.

In terms of underlying technology, the OM-1 is build around a Stacked BSI-CMOS sensor, while the GX800 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

OM-1 versus GX800 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

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 OM-1 provides a higher frame rate than the GX800. It can shoot video footage at 4K/60p, while the Panasonic is limited to 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the OM-1 has an electronic viewfinder (5760k 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 table below summarizes some of the other core capabilities of the OM System OM-1 and Panasonic GX800 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the OM-1 and the GX800 is in-body image stabilization (IBIS). The OM-1 reduces the risk of handshake-induced blur with all attached lenses, while the GX800 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 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, both cameras under consideration feature 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).

The OM System OM-1 and the Panasonic GX800 both have 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 OM-1 and the GX800 write their files to SDXC cards. The OM-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX800 only has one slot. The OM-1 supports UHS-II cards (on both slots), while the GX800 can use UHS-I 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 OM System OM-1 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 OM-1 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 OM System OM-1 (unlike the GX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the OM-1 and the GX800 have been discontinued, but can regularly be found used on ebay. The OM-1 was replaced by the OM System OM-1 II, while the GX800 does not have a direct successor. Further information on the features and operation of the OM-1 and GX800 can be found, respectively, in the OM System OM-1 Manual (free pdf) or the online Panasonic GX800 Manual.

Review summary

So what conclusions can be drawn? Is the OM System OM-1 better than the Panasonic GX800 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

  • More modern: Reflects 5 years and 1 month of technical progress since the GX800 launch.

ilogo

Reasons to prefer the Panasonic Lumix DMC-GX800:

  • More compact: Is smaller (107x65mm vs 135x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 330g or 55 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 (75 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in January 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the OM-1 is the clear winner of the match-up (21 : 5 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

OM-1 21:05 GX800

How about other alternatives? Do the specifications of the OM System OM-1 and the Panasonic GX800 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 OM-1 or the GX800 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 hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
