Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark III 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: Canon 5D Mark III vs Pentax K-70

An illustration of the physical size and weight of the Canon 5D Mark III and the Pentax K-70 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-70 can be obtained in two different colors (black, silver), while the 5D Mark III is only available in black.

Size Canon 5D Mark III vs Pentax K-70
Compare 5D Mark III versus K-70 top
Comparison 5D Mark III 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 (34 percent) than the Canon 5D Mark III. Moreover, the K-70 is markedly lighter (28 percent) than the 5D Mark III. 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 5D Mark III gets 950 shots out of its LP-E6 battery, while the K-70 can take 410 images on a single charge of its D-LI109 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

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 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-70 was launched at a markedly lower price (by 81 percent) than the 5D Mark III, 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 5D Mark III vs Pentax K-70

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 5D Mark III features a full frame sensor and the Pentax K-70 an APS-C sensor. The sensor area in the K-70 is 58 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.

Canon 5D Mark III and Pentax K-70 sensor measures

Despite having a smaller sensor, the K-70 offers a slightly higher resolution of 24 megapixels, compared with 22.1 MP of the 5D Mark III. 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 3.91μm versus 6.25μm for the 5D Mark III). However, it should be noted that the K-70 is much more recent (by 4 years and 3 months) than the 5D Mark III, 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-70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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

Unlike the 5D Mark III, 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 Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Pentax K-70 are ISO 100 to ISO 102400 (no boost).

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the K-70 provides a faster frame rate than the 5D Mark III. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 5D Mark III vs Pentax K-70

Beyond body and sensor, cameras can and do differ across a range of features. The 5D Mark III 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 5D Mark III has a higher magnification than the one of the K-70 (0.71x 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 Canon 5D Mark III and Pentax K-70 along with similar information for a selection of comparators.

One feature that is present on the 5D Mark III, 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 5D Mark III does not have a selfie-screen.

The Pentax K-70 has 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 5D Mark III writes its imaging data to Compact Flash or SDXC cards, while the K-70 uses SDXC cards. The 5D Mark III 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 K-70 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 5D Mark III cannot take advantage of Ultra High Speed SD cards.

It is notable that the 5D Mark III 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 Canon 5D Mark III (unlike the K-70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The K-70 is a recent model that features in the current product line-up of Pentax. In contrast, the 5D Mark III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 5D Mark III was succeeded by the Canon 5D Mark IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.

  • More compact: Is smaller (126x93mm vs 152x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 262g or 28 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (81 percent cheaper at launch).
  • More modern: Reflects 4 years and 3 months of technical progress since the 5D Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the K-70 is the clear winner of the contest (15 : 11 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 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 Canon 5D Mark III 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 5D Mark III and the K-70 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Canon 5D Mark III vs Pentax K-70

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
