Nikon D4 vs Pentax K-3 II

The Nikon D4 and the Pentax K-3 II are two digital cameras that were officially introduced, respectively, in January 2012 and April 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D4) and an APS-C (K-3 II) sensor. The Nikon has a resolution of 16.2 megapixels, whereas the Pentax provides 24.1 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 D4 and the Pentax K-3 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.

Body comparison

The physical size and weight of the Nikon D4 and the Pentax K-3 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.

The K-3 II can be obtained in two different colors (black, silver), while the D4 is only available in black.

Size Nikon D4 vs Pentax K-3 II
Compare D4 versus K-3 II top
Comparison D4 or K-3 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 II is considerably smaller (48 percent) than the Nikon D4. Moreover, the K-3 II is substantially lighter (40 percent) than the D4. 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 D4 gets 2600 shots out of its EN-EL18 battery, while the K-3 II can take 720 images on a single charge of its D-LI90 power pack. As can be seen in the images above, the D4 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-3 II, Pentax provides the D-BG5 vertical grip as an optional accessory (see here on eBay).

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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-3 II was launched at a markedly lower price (by 82 percent) than the D4, 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

The size of the imaging sensor is a crucial determinant 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 Nikon D4 features a full frame sensor and the Pentax K-3 II an APS-C sensor. The sensor area in the K-3 II 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Nikon D4 and Pentax K-3 II sensor measures

Despite having a smaller sensor, the K-3 II offers a higher resolution of 24.1 megapixels, compared with 16.2 MP of the D4. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.90μm versus 7.29μm for the D4). However, it should be noted that the K-3 II is much more recent (by 3 years and 3 months) than the D4, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the K-3 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-3 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-3 II for good quality output (200 dots per inch) amounts to 30.1 x 20 inch or 76.4 x 50.8 cm, for very good quality (250 dpi) 24.1 x 16 inch or 61.1 x 40.6 cm, and for excellent quality (300 dpi) 20.1 x 13.3 inch or 50.9 x 33.9 cm. The corresponding values for the Nikon D4 are 24.6 x 16.4 inch or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inch or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inch or 41.7 x 27.8 cm for excellent quality prints.

Unlike the D4, the K-3 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 Nikon D4 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-204800. The corresponding ISO settings for the Pentax K-3 II are ISO 100 to ISO 51200 (no boost).

D4 versus K-3 II MP

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"). Of the two cameras under review, the D4 has a notably higher overall DXO score than the K-3 II (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.5 EV of lower dynamic range, and 1.4 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the K-3 II provides a faster frame rate than the D4. It can shoot movie footage at 1080/60i, while the Nikon is limited to 1080/30p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D4 and the K-3 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%), but the viewfinder of the D4 has a higher magnification than the one of the K-3 II (0.70x 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 D4 and Pentax K-3 II in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the K-3 II and the D4 is in-body image stabilization (IBIS). The K-3 II reduces the risk of handshake-induced blur with all attached lenses, while the D4 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The Nikon D4 and the Pentax K-3 II both have 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 D4 writes its imaging data to Compact Flash or XQD cards, while the K-3 II uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

 

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 D4 and Pentax K-3 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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-3 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The K-3 II is a recent model that features in the current product line-up of Pentax. In contrast, the D4 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D4 was succeeded by the Nikon D4S. 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.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D4 and the Pentax K-3 II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Nikon D4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
  • Faster burst: Shoots at higher frequency (11 vs 8.3 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 (2600 versus 720) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in January 2012).

ilogo

Reasons to prefer the Pentax K-3 II:

  • More detail: Has more megapixels (24.1 vs 16.2MP), which boosts linear resolution by 22%.
  • 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 video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
  • More compact: Is smaller (131x100mm vs 160x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 540g or 40 percent) and is thus easier to take along.
  • 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.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
  • More modern: Reflects 3 years and 3 months of technical progress since the D4 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the K-3 II emerges as the winner of the match-up (12 : 9 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 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.

D4 09:12 K-3 II

How about other alternatives? Do the specifications of the Nikon D4 and the Pentax K-3 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 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 D4 or the K-3 II 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.

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 (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.

Notes: (+ +) 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
