Pentax K-1 II vs Nikon D1H

The Pentax K-1 II and the Nikon D1H are two digital cameras that were officially introduced, respectively, in February 2018 and February 2001. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (K-1 II) and an APS-C (D1H) sensor. The Pentax has a resolution of 36.2 megapixels, whereas the Nikon provides 2.6 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 Pentax K-1 II and the Nikon D1H? 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 Pentax K-1 II and the Nikon D1H 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.

The K-1 II can be obtained in two different colors (black, silver), while the D1H 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 Nikon D1H is considerably larger (59 percent) than the Pentax K-1 II. Moreover, the D1H is markedly heavier (9 percent) than the K-1 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 K-1 II gets 670 shots out of its Pentax D-LI90 battery, while the D1H can take 1200 images on a single charge of its Nikon EN-4 power pack. As can be seen in the images above, the D1H has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the K-1 II, Pentax provides the D-BG6 vertical grip as an optional accessory (see here on ebay).

Any camera decision will naturally be influenced heavily by the price. 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-1 II was launched at a markedly lower price (by 56 percent) than the D1H, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Pentax K-1 II features a full frame sensor and the Nikon D1H an APS-C sensor. The sensor area in the D1H 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 36.2MP, the K-1 II offers a higher resolution than the D1H (2.6MP), but the K-1 II has smaller individual pixels (pixel pitch of 4.88μm versus 11.93μm for the D1H). However, the K-1 II is a much more recent model (by 17 years) than the D1H, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the K-1 II has no anti-alias filter installed, so that it can capture all the detail its 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 Nikon D1H are 10 x 6.6 inches or 25.4 x 16.7 cm for good quality, 8 x 5.2 inches or 20.3 x 13.3 cm for very good quality, and 6.7 x 4.4 inches or 16.9 x 11.1 cm for excellent quality prints.

Unlike the D1H, 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 Pentax K-1 II has a native sensitivity range from ISO 100 to ISO 819200. The corresponding ISO settings for the Nikon D1H are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-3200.

In terms of underlying technology, the K-1 II is build around a CMOS sensor, while the D1H uses a CCD 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The K-1 II indeed provides movie recording capabilities, while the D1H does not. The highest resolution format that the K-1 II can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The K-1 II and the D1H are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the K-1 II offers a wider field of view (100%) than the one in the D1H (96%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-1 II has a higher magnification (0.70x vs 0.53x), 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 Pentax K-1 II, the Nikon D1H, and comparable cameras.

One feature that differentiates the K-1 II and the D1H is in-body image stabilization (IBIS). The K-1 II reduces the risk of handshake-induced blur with all attached lenses, while the D1H offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Pentax K-1 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 K-1 II writes its imaging data to SDXC cards, while the D1H uses Compact Flash cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D1H only has one slot.

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 Pentax K-1 II and Nikon D1H and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 II offers wifi support, while the D1H does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

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 D1H has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D1H was succeeded by the Nikon D2H. Further information on the features and operation of the K-1 II and D1H can be found, respectively, in the Pentax K-1 II Manual (free pdf) or the online Nikon D1H Manual.

Review summary

So how do things add up? Is the Pentax K-1 II better than the Nikon D1H or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Pentax K-1 II:

• More detail: Offers more megapixels (36.2 vs 2.6MP) with a 270% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• High quality composites: Can combine several shots after pixel-shifting its sensor.
• Better image quality: Features a larger and more technologically advanced imaging 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.
• Broader imaging potential: Can record not only still images but also 1080/60i movies.
• More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
• Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 120k dots).
• More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (137x110mm vs 157x153mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
• More modern: Reflects 17 years of technical progress since the D1H launch.

Reasons to prefer the Nikon D1H:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/8000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 4.4 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (1200 versus 670) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in February 2001).

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 II is the clear winner of the match-up (21 : 6 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 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 Pentax K-1 II and the Nikon D1H place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 K-1 II or the D1H. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated 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. 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.
