Olympus Stylus 1s vs Sigma fp

The Olympus Stylus 1s and the Sigma fp are two digital cameras that were revealed to the public, respectively, in April 2015 and July 2019. The Stylus 1s is a fixed lens compact, while the fp is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (Stylus 1s) and a full frame (fp) sensor. The Olympus has a resolution of 11.8 megapixels, whereas the Sigma 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 Stylus 1s and the Sigma fp 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 dimensions are rounded to the nearest millimeter.

Size Olympus Stylus 1s vs Sigma fp
Compare Stylus 1s versus fp top
Comparison Stylus 1s or fp rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sigma fp is notably smaller (22 percent) than the Olympus Stylus 1s. It is noteworthy in this context that the fp 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 fp 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 Olympus BLS-50 battery, while the fp can take 280 images on a single charge of its Sigma BP-51 power pack. The power pack in the fp can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 Stylus 1s was launched at a lower price than the fp, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Olympus Stylus 1s features a 1/1.7-inch sensor and the Sigma fp a full frame sensor. The sensor area in the fp is 1895 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 fp offers a 3:2 aspect.

Olympus Stylus 1s and Sigma fp sensor measures

With 24MP, the fp offers a higher resolution than the Stylus 1s (11.8MP), but the fp nevertheless has larger individual pixels (pixel pitch of 5.98μm versus 1.91μm for the Stylus 1s) due to its larger sensor. Moreover, the fp is a much more recent model (by 4 years and 2 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 Sigma fp implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the fp 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.

The Olympus Stylus 1s has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sigma fp are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 6-102400.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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.

Stylus 1s versus fp MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the Stylus 1s has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the fp relies on live view and the rear LCD for framing. That said, the fp can be equipped with an optional viewfinder – the EVF-11. The adjacent table lists some of the other core features of the Olympus Stylus 1s and Sigma fp along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The Stylus 1s has one, while the fp 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 fp 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 Sigma fp 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.

Concerning the storage of imaging data, both the Stylus 1s and the fp write their files to SDXC cards. The fp 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.

It is notable that the Stylus 1s offers wifi support, while the fp does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The fp is a recent model that features in the current product line-up of Sigma. In contrast, the Stylus 1s has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the Stylus 1s from Olympus. Further information on the features and operation of the Stylus 1s and fp can be found, respectively, in the Olympus Stylus 1s Manual (free pdf) or the online Sigma fp Manual.

Review summary

So what conclusions can be drawn? Is the Olympus Stylus 1s better than the Sigma fp or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Olympus Stylus 1s:

  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Ready to shoot: Has a lens built-in, whereas the fp requires a separate lens.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the fp).
  • Longer lasting: Can take more shots (450 versus 280) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in April 2015).

ilogo

Arguments in favor of the Sigma fp:

  • More detail: Has more megapixels (24 vs 11.8MP), which boosts linear resolution by 45%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (113x70mm vs 116x87mm) and will fit more readily into a bag.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
  • More modern: Reflects 4 years and 2 months of technical progress since the Stylus 1s launch.

If the count of relative strengths (bullet points above) is taken as a measure, the fp is the clear winner of the contest (19 : 10 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 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.

Stylus 1s 10:19 fp

How about other alternatives? Do the specifications of the Olympus Stylus 1s and the Sigma fp 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the Stylus 1s or the fp perform in practice. 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 expert reviews 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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.
