Body comparison

The physical size and weight of the Olympus Stylus 1 and the Pentax K-1 II 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 K-1 II can be obtained in two different colors (black, silver), while the Stylus 1 is only available in black.

Compare Stylus 1 versus K-1 II top
Comparison Stylus 1 or K-1 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 II is considerably larger (49 percent) than the Olympus Stylus 1. It is noteworthy in this context that the K-1 II is splash and dust-proof, while the Stylus 1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Stylus 1 has a lens built in, whereas the K-1 II 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 1 gets 410 shots out of its Olympus BLS-5 battery, while the K-1 II can take 670 images on a single charge of its Pentax D-LI90 power pack.

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 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 1 was launched at a lower price than the K-1 II, 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.

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 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 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 1 features a 1/1.7-inch sensor and the Pentax K-1 II a full frame sensor. The sensor area in the K-1 II is 1905 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 1 has a native 4:3 aspect ratio, while the one in the K-1 II offers a 3:2 aspect.

Olympus Stylus 1 and Pentax K-1 II sensor measures

With 36.2MP, the K-1 II offers a higher resolution than the Stylus 1 (11.8MP), but the K-1 II nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 1.91μm for the Stylus 1) due to its larger sensor. Moreover, the K-1 II is a much more recent model (by 4 years and 3 months) than the Stylus 1, 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 Pentax K-1 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 II for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Olympus Stylus 1 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 1, the K-1 II has the capacity to capture high quality composite images 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 1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Pentax K-1 II are ISO 100 to ISO 819200 (no boost).

In terms of underlying technology, the Stylus 1 is build around a BSI-CMOS sensor, while the K-1 II 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.

Stylus 1 versus K-1 II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the K-1 II provides a faster frame rate than the Stylus 1. It can shoot movie footage at 1080/60i, while the Olympus is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Stylus 1 has an electronic viewfinder (1440k dots), while the K-1 II has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the K-1 II has a higher magnification than the one of the Stylus 1 (0.70x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus Stylus 1 and Pentax K-1 II 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 1 has one, while the K-1 II does not. While the built-in flash of the Stylus 1 is not very powerful, it can at times be useful as a fill-in light.

The Olympus Stylus 1 and the Pentax K-1 II 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 1 and the K-1 II write their files to SDXC cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the Stylus 1 only has one slot. The K-1 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Stylus 1 cannot take advantage of Ultra High Speed SD cards.

It is notable that the K-1 II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The Stylus 1 does not feature such a mic input.

Studio photographers will appreciate that the Pentax K-1 II (unlike the Stylus 1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the K-1 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the Stylus 1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the Stylus 1 was succeeded by the Olympus Stylus 1s. Further information on the features and operation of the Stylus 1 and K-1 II can be found, respectively, in the Olympus Stylus 1 Manual (free pdf) or the online Pentax K-1 II Manual.

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • 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 movie framerates (1080/60i versus 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.58x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.

  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (670 versus 410) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 4 years and 3 months of technical progress since the Stylus 1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the K-1 II is the clear winner of the contest (23 : 9 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 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.

Stylus 1 09:23 K-1 II

How about other alternatives? Do the specifications of the Olympus Stylus 1 and the Pentax K-1 II place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 1 or the K-1 II 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 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
