OM System OM-1 II vs Sony A6100
The OM System OM-1 II and the Sony Alpha A6100 are two digital cameras that were announced, respectively, in January 2024 and August 2019. Both the OM-1 II and the A6100 are mirrorless interchangeable lens cameras that are based on a Four Thirds (OM-1 II) and an APS-C (A6100) sensor. The OM System has a resolution of 20.2 megapixels, whereas the Sony provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the OM System OM-1 II and the Sony Alpha A6100? 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 OM System OM-1 II and the Sony A6100 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 width, height and depth measures are rounded to the nearest millimeter.
The A6100 can be obtained in three different colors (black, silver, white), while the OM-1 II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6100 is considerably smaller (35 percent) than the OM System OM-1 II. Moreover, the A6100 is markedly lighter (34 percent) than the OM-1 II. It is worth mentioning in this context that the OM-1 II is splash and dust resistant, while the A6100 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (OM-1 II) and the Sony E-Mount Lens Catalog (A6100). 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 II gets 500 shots out of its OM System BLX-1 battery, while the A6100 can take 420 images on a single charge of its Sony NP-FW50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. 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 A6100 was launched at a markedly lower price (by 69 percent) than the OM-1 II, 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.
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the OM System OM-1 II features a Four Thirds sensor and the Sony A6100 an APS-C sensor. The sensor area in the A6100 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the OM-1 II has a native 4:3 aspect ratio, while the one in the A6100 offers a 3:2 aspect.
With 24MP, the A6100 offers a higher resolution than the OM-1 II (20.2MP), but the A6100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the OM-1 II) due to its larger sensor. However, the OM-1 II is a much more recent model (by 4 years and 5 months) than the A6100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the OM-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A6100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the OM System OM-1 II are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
Unlike the A6100, the OM-1 II 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 II 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 Alpha A6100 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-51200.
In terms of underlying technology, the OM-1 II is build around a Stacked BSI-CMOS sensor, while the A6100 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the OM-1 II provides a higher frame rate than the A6100. It can shoot video footage at 4K/60p, while the Sony is limited to 4K/30p.
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 OM-1 II offers a substantially higher resolution than the one in the A6100 (5760k vs 1440k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One feature that differentiates the OM-1 II and the A6100 is in-body image stabilization (IBIS). The OM-1 II reduces the risk of handshake-induced blur with all attached lenses, while the A6100 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 II and the Sony A6100 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 II writes its imaging data to SDXC cards, while the A6100 uses SDXC or Memory Stick PRO Duo cards. The OM-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the A6100 only has one slot. The OM-1 II supports UHS-II cards (on both slots), while the A6100 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 II and Sony Alpha A6100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the OM-1 II has a headphone jack, which is not present on the A6100 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Studio photographers will appreciate that the OM System OM-1 II (unlike the A6100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The OM-1 II is a recent model that features in the current product line-up of OM System. In contrast, the A6100 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A6100 was succeeded by the Sony A6600. Further information on the features and operation of the OM-1 II and A6100 can be found, respectively, in the OM System OM-1 II Manual (free pdf) or the online Sony A6100 Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the OM-1 II is the clear winner of the match-up (17 : 12 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 OM System OM-1 II and the Sony A6100 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the OM-1 II or the A6100. 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.
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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
