Nikon D850 vs Pentax K-70

The Nikon D850 and the Pentax K-70 are two digital cameras that were announced, respectively, in July 2017 and June 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D850) and an APS-C (K-70) sensor. The Nikon has a resolution of 45.4 megapixels, whereas the Pentax provides 24 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 D850 and the Pentax K-70? 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: Nikon D850 vs Pentax K-70

The side-by-side display below illustrates the physical size and weight of the Nikon D850 and the Pentax K-70. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The K-70 can be obtained in two different colors (black, silver), while the D850 is only available in black.

Size Nikon D850 vs Pentax K-70
Compare D850 versus K-70 top
Comparison D850 or K-70 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-70 is considerably smaller (35 percent) than the Nikon D850. Moreover, the K-70 is markedly lighter (32 percent) than the D850. 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 D850 gets 1840 shots out of its EN-EL15a battery, while the K-70 can take 410 images on a single charge of its D-LI109 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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

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-70 was launched at a markedly lower price (by 80 percent) than the D850, 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: Nikon D850 vs Pentax K-70

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D850 features a full frame sensor and the Pentax K-70 an APS-C sensor. The sensor area in the K-70 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.

Nikon D850 and Pentax K-70 sensor measures

With 45.4MP, the D850 offers a higher resolution than the K-70 (24MP), but the D850 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.91μm for the K-70) due to its larger sensor. Moreover, the D850 is a somewhat more recent model (by 1 year and 1 month) than the K-70, and its sensor might 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inch or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inch or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inch or 69.9 x 46.6 cm. The corresponding values for the Pentax K-70 are 30 x 20 inch or 76.2 x 50.8 cm for good quality, 24 x 16 inch or 61 x 40.6 cm for very good quality, and 20 x 13.3 inch or 50.8 x 33.9 cm for excellent quality prints.

The K-70 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the D850, the K-70 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 D850 has a native sensitivity range from ISO 64 to ISO 25600, which can be extended to ISO 32-102400. The corresponding ISO settings for the Pentax K-70 are ISO 100 to ISO 102400 (no boost).

D850 versus K-70 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D850 provides a higher video resolution than the K-70. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Nikon D850 vs Pentax K-70

Apart from body and sensor, cameras can and do differ across a range of features. The D850 and the K-70 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 D850 has a higher magnification than the one of the K-70 (0.75x 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 D850 and Pentax K-70 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D850, but is missing on the K-70 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The K-70 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 D850 does not have a selfie-screen.

The Nikon D850 and the Pentax K-70 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 D850 writes its imaging data to SDHC or XQD cards, while the K-70 uses SDXC cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the K-70 only has one slot. The D850 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the K-70 can use UHS-I cards (up to 104 MB/s).

It is notable that the D850 has a headphone jack, which is not present on the K-70 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 Nikon D850 (unlike the K-70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D850 and the K-70 are recent models that are part of the current product line-up. The K-70 replaced the earlier Pentax K-50, while the D850 followed on from the Nikon D810. 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.

  • More compact: Is smaller (126x93mm vs 146x124mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 317g or 32 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the D850 is the clear winner of the match-up (22 : 10 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 D850 and the Pentax K-70 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 says little about, for example, the shooting experience and imaging performance of the D850 and the K-70 in practical situations. 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: Nikon D850 vs Pentax K-70

This is why expert reviews 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 are only valid when referring to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
