Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z7 II and the Pentax K-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.

Body comparison

The physical size and weight of the Nikon Z7 II and the Pentax K-S1 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 measures are rounded to the nearest millimeter.

The K-S1 can be obtained in four different colors (black, grey, orange, white), while the Z7 II is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-S1 is notably smaller (17 percent) than the Nikon Z7 II. Moreover, the K-S1 is markedly lighter (21 percent) than the Z7 II. It is worth mentioning in this context that the Z7 II is splash and dust resistant, while the K-S1 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 Z7 II gets 420 shots out of its Nikon EN-EL15c battery, while the K-S1 can take 410 images on a single charge of its Pentax D-LI109 power pack. The power pack in the Z7 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. 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 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 K-S1 was launched at a markedly lower price (by 75 percent) than the Z7 II, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon Z7 II features a full frame sensor and the Pentax K-S1 an APS-C sensor. The sensor area in the K-S1 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 45.4MP, the Z7 II offers a higher resolution than the K-S1 (20MP), but the Z7 II nevertheless has marginally larger individual pixels (pixel pitch of 4.35μm versus 4.28μm for the K-S1) due to its larger sensor. Moreover, the Z7 II is a much more recent model (by 6 years and 1 month) than the K-S1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 Nikon Z7 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z7 II for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Pentax K-S1 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Z7 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Z7 II has a native sensitivity range from ISO 64 to ISO 25600, which can be extended to ISO 32-102400. The corresponding ISO settings for the Pentax K-S1 are ISO 100 to ISO 51200 (no boost).

In terms of underlying technology, the Z7 II is build around a BSI-CMOS sensor, while the K-S1 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the Z7 II provides substantially higher image quality than the K-S1, with an overall score that is 22 points higher. This advantage is based on 2.8 bits higher color depth, 1.7 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Z7 II provides a higher video resolution than the K-S1. It can shoot video footage at 4K/60p, while the Pentax is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the Z7 II has an electronic viewfinder (3690k dots), while the K-S1 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 Z7 II has a higher magnification than the one of the K-S1 (0.80x vs 0.63x), 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 Nikon Z7 II and Pentax K-S1 in connection with corresponding information for a sample of similar cameras.

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

One feature that is present on the Z7 II, but is missing on the K-S1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 Z7 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 Nikon Z7 II 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.

The Z7 II writes its imaging data to CFexpress (type B) or SDXC cards, while the K-S1 uses SDXC cards. The Z7 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the K-S1 only has one slot. The Z7 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the K-S1 can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

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 Nikon Z7 II and Pentax K-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z7 II has a microphone port, which is missing on the K-S1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The Z7 II is a recent model that features in the current product line-up of Nikon. In contrast, the K-S1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the K-S1 was succeeded by the Pentax K-S2. Further information on the features and operation of the Z7 II and K-S1 can be found, respectively, in the Nikon Z7 II Manual (free pdf) or the online Pentax K-S1 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Nikon Z7 II or the Pentax K-S1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Pentax K-S1:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More compact: Is smaller (121x93mm vs 134x101mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 147g or 21 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in August 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the Z7 II is the clear winner of the match-up (29 : 6 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.

How about other alternatives? Do the specifications of the Nikon Z7 II and the Pentax K-S1 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the Z7 II or the K-S1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
