Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic S5 II and the Pentax K-1. 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.

The K-1 can be obtained in two different colors (black, silver), while the S5 II is only available in black.

Size Panasonic S5 II vs Pentax K-1
Compare S5 II versus K-1 top
Comparison S5 II or K-1 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 is notably larger (10 percent) than the Panasonic S5 II. Moreover, the K-1 is substantially heavier (36 percent) than the S5 II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 S5 II gets 370 shots out of its Panasonic DMW-BLK22 battery, while the K-1 can take 760 images on a single charge of its Pentax D-LI90 power pack. The power pack in the S5 II 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.

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 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 K-1 was somewhat cheaper (by 10 percent) than the S5 II at launch, but both cameras fall into the same price category. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the K-1 is 2 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Panasonic S5 II and Pentax K-1 sensor measures

With 36.2MP, the K-1 offers a higher resolution than the S5 II (24MP), but the K-1 has smaller individual pixels (pixel pitch of 4.88μm versus 5.94μm for the S5 II). Yet, the S5 II is a much more recent model (by 6 years and 10 months) than the K-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 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 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 Panasonic S5 II are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The S5 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Panasonic Lumix DC-S5 II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).

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.

S5 II versus K-1 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the S5 II has an electronic viewfinder (3680k dots), while the K-1 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 S5 II has a higher magnification than the one of the K-1 (0.78x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Panasonic S5 II, the Pentax K-1, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S5 II has a touchscreen, while the K-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The S5 II 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 K-1 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 S5 II 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 S5 II and the Pentax K-1 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 S5 II and the K-1 write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The S5 II supports UHS-II cards (on both slots), while the K-1 can use UHS-I cards.

Studio photographers will appreciate that the Pentax K-1 (unlike the S5 II) 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 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The S5 II is a recent model that features in the current product line-up of Panasonic. In contrast, the K-1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the K-1 was succeeded by the Pentax K-1 II. Further information on the features and operation of the S5 II and K-1 can be found, respectively, in the Panasonic S5 II Manual (free pdf) or the online Pentax K-1 Manual.

Review summary

So how do things add up? Is the Panasonic S5 II better than the Pentax K-1 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Panasonic Lumix DC-S5 II:

  • Better video: Provides higher definition movie capture (6K/30p vs 1080/60i).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (1840k vs 1037k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (9 vs 4.4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Less heavy: Is lighter (by 270g or 27 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 6 years and 10 months of technical progress since the K-1 launch.

ilogo

Reasons to prefer the Pentax K-1:

  • More detail: Has more megapixels (36.2 vs 24MP), which boosts linear resolution by 23%.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Longer lasting: Gets more shots (760 versus 370) out of a single battery charge.
  • 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.
  • More heavily discounted: Has been around for much longer (launched in February 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the S5 II is the clear winner of the match-up (17 : 8 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 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.

S5 II 17:08 K-1

How about other alternatives? Do the specifications of the Panasonic S5 II and the Pentax K-1 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the S5 II and the K-1 in practical situations. 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 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], 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 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, please note that some of the review sites have changed their methodology and reporting over time.
