OM System OM-1 vs Sony A58

The OM System OM-1 and the Sony Alpha SLT-A58 are two digital cameras that were announced, respectively, in February 2022 and February 2013. The OM-1 is a mirrorless interchangeable lens camera, while the A58 is a DSLR. The cameras are based on a Four Thirds (OM-1) and an APS-C (A58) sensor. The OM System has a resolution of 20.2 megapixels, whereas the Sony provides 19.8 MP.

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

Body comparison

The physical size and weight of the OM System OM-1 and the Sony A58 are illustrated in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

Size OM System OM-1 vs Sony A58
Compare OM-1 versus A58 top
Comparison OM-1 or A58 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is somewhat smaller (1 percent) than the OM System OM-1. Moreover, the A58 is markedly lighter (18 percent) than the OM-1. It is worth mentioning in this context that the OM-1 is splash and dust resistant, while the A58 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the OM-1 gets 520 shots out of its OM System BLX-1 battery, while the A58 can take 690 images on a single charge of its Sony NP-FM500H 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A58 was launched at a markedly lower price (by 73 percent) than the OM-1, 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

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the OM System OM-1 features a Four Thirds sensor and the Sony A58 an APS-C sensor. The sensor area in the A58 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 has a native 4:3 aspect ratio, while the one in the A58 offers a 3:2 aspect.

OM System OM-1 and Sony A58 sensor measures

Despite having a smaller sensor, the OM System OM-1 offers a higher resolution of 20.2 megapixels, compared with 19.8 MP of the Sony A58. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.31μm for the A58). However, it should be noted that the OM-1 is much more recent (by 8 years and 11 months) than the A58, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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.

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

Unlike the A58, 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 Alpha SLT-A58 are ISO 100 to ISO 16000, 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 A58 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 A58 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The OM-1 has a touchscreen, while the A58 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The OM-1 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A58 does not have a selfie-screen.

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 OM-1 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 OM System OM-1 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 OM-1 writes its imaging data to SDXC cards, while the A58 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 A58 only has one slot. The OM-1 supports UHS-II cards (on both slots), while the A58 cannot take advantage of Ultra High Speed SD cards.

It is notable that the OM-1 has a headphone jack, which is not present on the A58 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 (unlike the A58) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the OM-1 and the A58 have been discontinued, but can regularly be found used on ebay. The A58 was replaced by the Sony A68, while the OM-1 was followed by the OM System OM-1 II. Further information on the features and operation of the OM-1 and A58 can be found, respectively, in the OM System OM-1 Manual (free pdf) or the online Sony A58 Manual.

ilogo

Arguments in favor of the Sony Alpha SLT-A58:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Less heavy: Has a lower weight (by 107g or 18 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (690 versus 520) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2013).

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 (26 : 6 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 26:06 A58

How about other alternatives? Do the specifications of the OM System OM-1 and the Sony A58 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 remains incomplete and does no justice, for example, to the way the OM-1 or the A58 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
