OM System OM-1 vs Sony RX100 VII

The OM System OM-1 and the Sony Cyber-shot DSC-RX100 VII are two digital cameras that were announced, respectively, in February 2022 and July 2019. The OM-1 is a mirrorless interchangeable lens camera, while the RX100 VII is a fixed lens compact. The cameras are based on a Four Thirds (OM-1) and an one-inch (RX100 VII) sensor. The OM System has a resolution of 20.2 megapixels, whereas the Sony provides 20 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 Sony RX100 VII. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

Compare OM-1 versus RX100 VII top
Comparison OM-1 or RX100 VII rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 VII is considerably smaller (52 percent) than the OM System OM-1. It is worth mentioning in this context that the OM-1 is splash and dust resistant, while the RX100 VII does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 VII has a lens built in, whereas the OM-1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the OM-1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the OM-1 gets 520 shots out of its OM System BLX-1 battery, while the RX100 VII can take 260 images on a single charge of its Sony NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 RX100 VII was launched at a lower price than the OM-1, despite having a lens built in. 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

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.

Of the two cameras under consideration, the OM System OM-1 features a Four Thirds sensor and the Sony RX100 VII an one-inch sensor. The sensor area in the RX100 VII is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the OM-1 has a native 4:3 aspect ratio, while the one in the RX100 VII offers a 3:2 aspect.

OM System OM-1 and Sony RX100 VII sensor measures

With 20.2MP, the OM-1 offers a slightly higher resolution than the RX100 VII (20MP), but the OM-1 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 VII) due to its larger sensor. Moreover, the OM-1 is a much more recent model (by 2 years and 6 months) than the RX100 VII, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the OM-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the RX100 VII, 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 Sony Cyber-shot DSC-RX100 VII are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the OM-1 is build around a Stacked BSI-CMOS sensor, while the RX100 VII uses a BSI-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 RX100 VII MP

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

One difference between the cameras concerns the presence of an on-board flash. The RX100 VII has one, while the OM-1 does not. While the built-in flash of the RX100 VII is not very powerful, it can at times be useful as a fill-in light.

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 Sony RX100 VII 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.

The OM-1 writes its imaging data to SDXC cards, while the RX100 VII uses SDXC or Memory Stick PRO Duo cards. The OM-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX100 VII only has one slot. The OM-1 supports UHS-II cards (on both slots), while the RX100 VII can use UHS-I cards.

It is notable that the OM-1 has a hotshoe, while the RX100 VII 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 RX100 VII) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The RX100 VII is a recent model that features in the current product line-up of Sony. In contrast, the OM-1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the OM-1 was succeeded by the OM System OM-1 II. Further information on the features and operation of the OM-1 and RX100 VII can be found, respectively, in the OM System OM-1 Manual (free pdf) or the online Sony RX100 VII Manual.

ilogo

Advantages of the Sony Cyber-shot DSC-RX100 VII:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Faster burst: Shoots at higher frequency (90 vs 10 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the OM-1 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 135x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the OM-1).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in July 2019).

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 (22 : 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. 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 22:09 RX100 VII

How about other alternatives? Do the specifications of the OM System OM-1 and the Sony RX100 VII place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the OM-1 and the RX100 VII in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

padding

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
