Olympus Stylus 1s vs Panasonic S1
The Olympus Stylus 1s and the Panasonic Lumix DC-S1 are two digital cameras that were announced, respectively, in April 2015 and February 2019. The Stylus 1s is a fixed lens compact, while the S1 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (Stylus 1s) and a full frame (S1) sensor. The Olympus has a resolution of 11.8 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.
Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Stylus 1s and the Panasonic Lumix DC-S1? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus Stylus 1s and the Panasonic S1. 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 measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 is considerably larger (62 percent) than the Olympus Stylus 1s. It is noteworthy in this context that the S1 is splash and dust-proof, while the Stylus 1s does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Stylus 1s has a lens built in, whereas the S1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the Stylus 1s gets 450 shots out of its BLS-50 battery, while the S1 can take 400 images on a single charge of its DMW-BLJ31 power pack. The power pack in the S1 can be charged via the USB port, 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Stylus 1s was launched at a lower price than the S1, despite having a lens built in. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus Stylus 1s features a 1/1.7-inch sensor and the Panasonic S1 a full frame sensor. The sensor area in the S1 is 1870 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 1.0. The sensor in the Stylus 1s has a native 4:3 aspect ratio, while the one in the S1 offers a 3:2 aspect.
With 24MP, the S1 offers a higher resolution than the Stylus 1s (11.8MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 1.91μm for the Stylus 1s) due to its larger sensor. Moreover, the S1 is a much more recent model (by 3 years and 9 months) than the Stylus 1s, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Panasonic S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1 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 Stylus 1s are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 cm for excellent quality prints.
Unlike the Stylus 1s, the S1 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 Stylus 1s has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DC-S1 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S1 provides a better video resolution than the Stylus 1s. It can shoot movie footage at 4K/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the S1 offers a substantially higher resolution than the one in the Stylus 1s (5760k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus Stylus 1s and Panasonic S1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The Stylus 1s has one, while the S1 does not. While the built-in flash of the Stylus 1s is not very powerful, it can at times be useful as a fill-in light.
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 S1 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 Olympus Stylus 1s and the Panasonic S1 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 Stylus 1s writes its imaging data to SDXC cards, while the S1 uses SDHC or XQD cards. The S1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Stylus 1s only has one slot. The S1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the Stylus 1s cannot take advantage of Ultra High Speed SD cards.
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 Olympus Stylus 1s and Panasonic Lumix DC-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The Stylus 1s does not feature such a mic input.
Studio photographers will appreciate that the Panasonic S1 (unlike the Stylus 1s) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the Stylus 1s and the S1 are recent models that are part of the current product line-up. The Stylus 1s replaced the earlier Olympus Stylus 1, while the S1 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.
So what is the bottom line? Which of the two cameras – the Olympus Stylus 1s or the Panasonic S1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus Stylus 1s:

If the count of individual advantages (bullet points above) is taken as a guide, the S1 is the clear winner of the contest (28 : 7 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 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.
How about other alternatives? Do the specifications of the Olympus Stylus 1s and the Panasonic S1 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Stylus 1s or the S1. 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.
This is why expert reviews 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], 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
