Canon 1Ds vs Pentax K-1 II
The Canon EOS-1Ds and the Pentax K-1 II are two digital cameras that were announced, respectively, in September 2002 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Canon has a resolution of 11 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 Canon EOS-1Ds and the Pentax K-1 II? 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.
An illustration of the physical size and weight of the Canon 1Ds and the Pentax K-1 II is provided 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 1Ds 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 II is considerably smaller (39 percent) than the Canon 1Ds. Moreover, the K-1 II is markedly lighter (20 percent) than the 1Ds. 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 1Ds gets 600 shots out of its NP-E3 battery, while the K-1 II can take 670 images on a single charge of its D-LI90 power pack. As can be seen in the images above, the 1Ds 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).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 K-1 II was launched at a markedly lower price (by 78 percent) than the 1Ds, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. 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.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the K-1 II is 1 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 36.2MP, the K-1 II offers a higher resolution than the 1Ds (11MP), but the K-1 II has smaller individual pixels (pixel pitch of 4.88μm versus 8.83μm for the 1Ds). Yet, the K-1 II is a much more recent model (by 15 years and 5 months) than the 1Ds, 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 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 Canon 1Ds are 20.3 x 13.5 inches or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inches or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inches or 34.4 x 22.9 cm for excellent quality prints.
Unlike the 1Ds, 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 Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Pentax K-1 II are ISO 100 to ISO 819200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The K-1 II indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the K-1 II can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds and the K-1 II 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 viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The following table reports on some other key feature differences and similarities of the Canon 1Ds, the Pentax K-1 II, and comparable cameras.

One feature that differentiates the K-1 II and the 1Ds is in-body image stabilization (IBIS). The K-1 II reduces the risk of handshake-induced blur with all attached lenses, while the 1Ds 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 1Ds writes its imaging data to Compact Flash cards, while the K-1 II uses SDXC cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1Ds 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 Canon EOS-1Ds and Pentax K-1 II 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, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1Ds 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 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 1Ds has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1Ds was succeeded by the Canon 1Ds Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.
So how do things add up? Is the Canon 1Ds better than the Pentax K-1 II or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS-1Ds:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- More heavily discounted: Has been available for much longer (launched in September 2002).
Arguments in favor of the Pentax K-1 II:
- More detail: Has more megapixels (36.2 vs 11MP), which boosts linear resolution by 81%.
- 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.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- 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.
- Faster burst: Shoots at higher frequency (4.4 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (137x110mm vs 156x158mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 255g or 20 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (670 versus 600) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- 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 (78 percent cheaper at launch).
- More modern: Reflects 15 years and 5 months of technical progress since the 1Ds launch.
If the number of relative strengths (bullet points above) is taken as a guide, the K-1 II is the clear winner of the contest (18 : 3 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon 1Ds and the Pentax K-1 II 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 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 1Ds and the K-1 II 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.
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], 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 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 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.
