Olympus E-PM1 vs Panasonic S1H

The Olympus PEN E-PM1 and the Panasonic Lumix DC-S1H are two digital cameras that were revealed to the public, respectively, in June 2011 and May 2019. Both the E-PM1 and the S1H are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-PM1) and a full frame (S1H) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Panasonic provides 24 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 Olympus E-PM1 and the Panasonic S1H are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the S1H is only available in black.

Compare E-PM1 versus S1H top
Comparison E-PM1 or S1H rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1H is considerably larger (145 percent) than the Olympus E-PM1. Moreover, the S1H is substantially heavier (297 percent) than the E-PM1. It is noteworthy in this context that the S1H is splash and dust-proof, while the E-PM1 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 E-PM1 gets 330 shots out of its Olympus BLS-5 battery, while the S1H can take 400 images on a single charge of its Panasonic DMW-BLJ31 power pack. The power pack in the S1H can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 E-PM1 was launched at a markedly lower price (by 88 percent) than the S1H, 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. 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 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. 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 Olympus E-PM1 features a Four Thirds sensor and the Panasonic S1H a full frame sensor. The sensor area in the S1H is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-PM1 has a native 4:3 aspect ratio, while the one in the S1H offers a 3:2 aspect.

Olympus E-PM1 and Panasonic S1H sensor measures

With 24MP, the S1H offers a higher resolution than the E-PM1 (12.2MP), but the S1H nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.29μm for the E-PM1) due to its larger sensor. Moreover, the S1H is a much more recent model (by 7 years and 11 months) than the E-PM1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Panasonic S1H implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1H 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 Olympus E-PM1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.

Unlike the E-PM1, the S1H has the capacity to capture high quality composite images (96MP) 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 Olympus PEN E-PM1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DC-S1H are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-PM1 versus S1H MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the S1H provides a better video resolution than the E-PM1. It can shoot movie footage at 6K/30p, while the Olympus is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the S1H has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Olympus E-PM1 and Panasonic S1H in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S1H has a touchscreen, while the E-PM1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The S1H 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-PM1 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 S1H 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 Panasonic S1H 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.

Concerning the storage of imaging data, both the E-PM1 and the S1H write their files to SDXC cards. The S1H features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PM1 only has one slot. The S1H supports UHS-II cards (on both slots), while the E-PM1 cannot take advantage of Ultra High Speed SD cards.

It is notable that the S1H offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-PM1 does not provide wifi capability.

Studio photographers will appreciate that the Panasonic S1H (unlike the E-PM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1H is a recent model that features in the current product line-up of Panasonic. In contrast, the E-PM1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-PM1 was succeeded by the Olympus E-PM2. Further information on the features and operation of the E-PM1 and S1H can be found, respectively, in the Olympus E-PM1 Manual (free pdf) or the online Panasonic S1H Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the S1H is the clear winner of the contest (31 : 4 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-PM1 04:31 S1H

How about other alternatives? Do the specifications of the Olympus E-PM1 and the Panasonic S1H 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-PM1 and the S1H in practical situations. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
