Nikon D3X vs Pentax K-3 II
The Nikon D3X and the Pentax K-3 II are two digital cameras that were announced, respectively, in December 2008 and April 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D3X) and an APS-C (K-3 II) sensor. The Nikon has a resolution of 24.4 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 D3X 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.
An illustration of the physical size and weight of the Nikon D3X and the Pentax K-3 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-3 II can be obtained in two different colors (black, silver), while the D3X 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-3 II is considerably smaller (48 percent) than the Nikon D3X. Moreover, the K-3 II is substantially lighter (37 percent) than the D3X. 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 D3X gets 4400 shots out of its EN-EL4a 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 D3X 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).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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-3 II was launched at a markedly lower price (by 86 percent) than the D3X, 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D3X 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.
With 24.4MP, the D3X offers a slightly higher resolution than the K-3 II (24.1MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.90μm for the K-3 II) due to its larger sensor. However, the K-3 II is a much more recent model (by 6 years and 4 months) than the D3X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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.
Unlike the D3X, 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 D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. The corresponding ISO settings for the Pentax K-3 II are ISO 100 to ISO 51200 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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. Of the two cameras under review, the D3X has a notably higher overall DXO score than the K-3 II (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.1 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. 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-3 II indeed provides for movie recording, while the D3X does not. The highest resolution format that the K-3 II can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The D3X 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 D3X 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 following table reports on some other key feature differences and similarities of the Nikon D3X, the Pentax K-3 II, and comparable cameras.

One feature that differentiates the K-3 II and the D3X is in-body image stabilization (IBIS). The K-3 II reduces the risk of handshake-induced blur with all attached lenses, while the D3X offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The Nikon D3X 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 D3X writes its imaging data to Compact Flash 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.
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 D3X 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.
Both the D3X and the K-3 II have been discontinued, but can regularly be found used on ebay. The K-3 II was replaced by the Pentax K-3 III, while the D3X does not have a direct successor. Further information on the features and operation of the D3X and K-3 II can be found, respectively, in the Nikon D3X Manual (free pdf) or the online Pentax K-3 II Manual.
So how do things add up? Is the Nikon D3X better than the Pentax K-3 II or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D3X:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores markedly higher (8 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 (0.8 stops ISO advantage).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (4400 versus 720) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in December 2008).
Arguments in favor of the Pentax K-3 II:
- 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 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 922k dots).
- Faster burst: Shoots at higher frequency (8.3 vs 5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (131x100mm vs 160x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 460g or 37 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 (86 percent cheaper at launch).
- More modern: Reflects 6 years and 4 months of technical progress since the D3X launch.
If the number of relative strengths (bullet points above) is taken as a guide, the K-3 II is the clear winner of the contest (13 : 8 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 Nikon D3X 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 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 D3X and the K-3 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], 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.

The above review scores should be interpreted 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 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.
