Nikon D1 vs Pentax K-1
The Nikon D1 and the Pentax K-1 are two digital cameras that were officially introduced, respectively, in June 1999 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D1) and a full frame (K-1) sensor. The Nikon has a resolution of 2.6 megapixels, whereas the Pentax provides 36.2 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 Nikon D1 and the Pentax K-1? 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.
The physical size and weight of the Nikon D1 and the Pentax K-1 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 can be obtained in two different colors (black, silver), while the D1 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-1 is considerably smaller (37 percent) than the Nikon D1. Moreover, the K-1 is markedly lighter (8 percent) than the D1. 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.
As can be seen in the images above, the D1 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, Pentax provides the D-BG6 vertical grip as an optional accessory (see here on eBay).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-1 was launched at a markedly lower price (by 67 percent) than the D1, 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D1 features an APS-C sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 36.2MP, the K-1 offers a higher resolution than the D1 (2.6MP), but the K-1 has smaller individual pixels (pixel pitch of 4.88μm versus 11.93μm for the D1). Yet, the K-1 is a much more recent model (by 16 years and 8 months) than the D1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 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 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 Nikon D1 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 D1, the K-1 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 Nikon D1 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-6400. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).
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 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 cannot only take still pictures, but also record videos. The K-1 indeed provides for movie recording, while the D1 does not. The highest resolution format that the K-1 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The D1 and the K-1 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 offers a wider field of view (100%) than the one in the D1 (96%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-1 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 table below summarizes some of the other core capabilities of the Nikon D1 and Pentax K-1 in connection with corresponding information for a sample of similar cameras.

|Sony A99 II||2400||Y||3.0||1229||full-flex||n||1/8000s||12.0||n||Y|
One feature that differentiates the K-1 and the D1 is in-body image stabilization (IBIS). The K-1 reduces the risk of handshake-induced blur with all attached lenses, while the D1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The Pentax K-1 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 D1 writes its imaging data to Compact Flash cards, while the K-1 uses SDXC cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D1 only has one slot.
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 D1 and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Pentax K-1 II||Y||stereo||mono||Y||Y||micro||2.0||Y||-||-|
|Sony A99 II||Y||stereo||mono||Y||Y||micro||2.0||Y||Y||Y|
It is notable that the K-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D1 does not provide wifi capability.
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 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the D1 and the K-1 have been discontinued, but can regularly be found used on eBay. The D1 was replaced by the Nikon D1X, while the K-1 was followed by the Pentax K-1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Pentax websites.
So how do things add up? Is the Nikon D1 better than the Pentax K-1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D1:

If the number of relative strengths (bullet points above) is taken as a guide, the K-1 is the clear winner of the contest (22 : 4 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D1 or the K-1. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 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.
