Body comparison: Canon 1D Mark IV vs Pentax K-1 II

The physical size and weight of the Canon 1D Mark IV and the Pentax K-1 II 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.

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 (38 percent) than the Canon 1D Mark IV. Moreover, the K-1 II is markedly lighter (18 percent) than the 1D Mark IV. 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 1D Mark IV gets 1500 shots out of its LP-E4 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 1D Mark IV 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 price is, of course, an important factor in any camera decision. 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 II was launched at a markedly lower price (by 60 percent) than the 1D Mark IV, 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.

Sensor comparison: Canon 1D Mark IV vs Pentax K-1 II

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Pentax K-1 II a full frame sensor. The sensor area in the K-1 II is 66 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 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 1D Mark IV (16MP), but the K-1 II has smaller individual pixels (pixel pitch of 4.88μm versus 5.70μm for the 1D Mark IV). Yet, the K-1 II is a much more recent model (by 8 years and 4 months) than the 1D Mark IV, 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.

Unlike the 1D Mark IV, 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-1D Mark IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. 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 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the K-1 II provides a faster frame rate than the 1D Mark IV. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison: Canon 1D Mark IV vs Pentax K-1 II

Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark IV 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 following table reports on some other key feature differences and similarities of the Canon 1D Mark IV, the Pentax K-1 II, and comparable cameras.

One feature that differentiates the K-1 II and the 1D Mark IV is in-body image stabilization (IBIS). The K-1 II reduces the risk of handshake-induced blur with all attached lenses, while the 1D Mark IV has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The 1D Mark IV writes its imaging data to Compact Flash cards, while the K-1 II uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Connectivity comparison: Canon 1D Mark IV vs Pentax K-1 II

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-1D Mark IV 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 1D Mark IV does not offer wifi capability.

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

The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the 1D Mark IV has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the 1D Mark IV from Canon.

Review summary: Canon 1D Mark IV vs Pentax K-1 II

So what is the bottom line? Is the Canon 1D Mark IV better than the Pentax K-1 II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS-1D Mark IV:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Faster burst: Shoots at higher frequency (10 vs 4.4 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1500 versus 670) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in October 2009).

Reasons to prefer the Pentax K-1 II:

• More detail: Has more megapixels (36.2 vs 16MP), which boosts linear resolution by 50%.
• 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: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: Larger sensor generates images with better, more accurate colors.
• More dynamic range: Capable of capturing a wider spectrum of light and dark details.
• Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
• More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
• More compact: Is smaller (137x110mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 220g or 18 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Reflects 8 years and 4 months of technical progress since the 1D Mark IV 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 : 5 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1D Mark IV or the K-1 II handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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. 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.
