Body comparison

An illustration of the physical size and weight of the Pentax K-3 II and the Canon 6D Mark II is provided 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-3 II can be obtained in two different colors (black, silver), while the 6D Mark II is only available in black.

Compare K-3 II versus 6D Mark II top
Comparison K-3 II or 6D Mark II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 6D Mark II is notably larger (22 percent) than the Pentax K-3 II. However, the 6D Mark II is slightly lighter (4 percent) than the K-3 II. 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 K-3 II gets 720 shots out of its Pentax D-LI90 battery, while the 6D Mark II can take 1200 images on a single charge of its Canon LP-E6N power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 45 percent) than the 6D Mark II, 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.

Sensor comparison

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 Pentax K-3 II features an APS-C sensor and the Canon 6D Mark II a full frame sensor. The sensor area in the 6D Mark II is 135 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.

Pentax K-3 II and Canon 6D Mark II sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the K-3 II (24.1MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 3.90μm for the K-3 II) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 2 years and 2 months) than the K-3 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the 6D Mark II, 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 Pentax K-3 II has a native sensitivity range from ISO 100 to ISO 51200. The corresponding ISO settings for the Canon EOS 6D Mark II are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.

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.

K-3 II versus 6D Mark II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the 6D Mark II has a markedly higher DXO score than the K-3 II (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1.7 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 6D Mark II provides a faster frame rate than the K-3 II. It can shoot movie footage at 1080/60p, while the Pentax is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The K-3 II and the 6D Mark 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 viewfinder in the K-3 II offers a wider field of view (100%) than the one in the 6D Mark II (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 6D Mark II has a higher magnification (0.72x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Pentax K-3 II and Canon 6D Mark II along with similar information for a selection of comparators.

One feature that differentiates the K-3 II and the 6D Mark II is in-body image stabilization (IBIS). The K-3 II reduces the risk of handshake-induced blur with all attached lenses, while the 6D Mark II offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The 6D Mark II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the K-3 II does not have a selfie-screen.

The Pentax K-3 II and the Canon 6D Mark 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.

Concerning the storage of imaging data, both the K-3 II and the 6D Mark II write their files to SDXC cards. The K-3 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 6D Mark II only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the K-3 II has a headphone jack, which is not present on the 6D Mark II This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Pentax K-3 II (unlike the 6D Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that both cameras feature internal geolocalization sensors and can record GPS coordinates in their EXIF data.

The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the K-3 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the K-3 II was succeeded by the Pentax K-3 III. Further information on the features and operation of the K-3 II and 6D Mark II can be found, respectively, in the Pentax K-3 II Manual (free pdf) or the online Canon 6D Mark II Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Pentax K-3 II or the Canon 6D Mark II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages 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.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.7 EV of extra DR).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8.3 vs 6.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 144x111mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • 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 (45 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in April 2015).

ilogo

Arguments in favor of the Canon EOS 6D Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.72x vs 0.63x).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Longer lasting: Gets more shots (1200 versus 720) out of a single battery charge.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 2 years and 2 months of technical progress since the K-3 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the K-3 II comes out slightly ahead of the 6D Mark II (15 : 14 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.

K-3 II 15:14 6D Mark II

How about other alternatives? Do the specifications of the Pentax K-3 II and the Canon 6D Mark 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 remains incomplete and does no justice, for example, to the way the K-3 II or the 6D Mark 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
