Pentax K-70 vs Sony A7C
The Pentax K-70 and the Sony Alpha A7C are two digital cameras that were announced, respectively, in June 2016 and September 2020. The K-70 is a DSLR, while the A7C is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (K-70) and a full frame (A7C) sensor. Both cameras offer a resolution of 24 megapixels.
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 Pentax K-70 and the Sony Alpha A7C? 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 Pentax K-70 and the Sony A7C are illustrated 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.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7C is notably smaller (25 percent) than the Pentax K-70. Moreover, the A7C is markedly lighter (26 percent) than the K-70. 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-70 gets 410 shots out of its Pentax D-LI109 battery, while the A7C can take 740 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A7C can be charged via the USB port, which can be very convenient when travelling.

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 64 percent) than the A7C, 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-70 features an APS-C sensor and the Sony A7C a full frame sensor. The sensor area in the A7C is 131 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.
Even though the A7C has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the A7C has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.91μm for the K-70), which gives it a potential advantage in terms of light gathering capacity. In addition, the A7C is much more recent (by 4 years and 3 months) than the K-70, and its sensor will have benefitted from technological advances during this time. 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.
Unlike the A7C, 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 Pentax K-70 has a native sensitivity range from ISO 100 to ISO 102400. The corresponding ISO settings for the Sony Alpha A7C are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
In terms of underlying technology, the K-70 is build around a CMOS sensor, while the A7C uses a BSI-CMOS imager. 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7C provides a better video resolution than the K-70. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60i.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7C has an electronic viewfinder (2360k dots), while the K-70 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the K-70 has a higher magnification than the one of the A7C (0.63x vs 0.59x), 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 Pentax K-70 and Sony A7C in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The K-70 has one, while the A7C does not. While the built-in flash of the K-70 is not very powerful, it can at times be useful as a fill-in light.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7C is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Pentax K-70 and the Sony A7C 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 K-70 writes its imaging data to SDXC cards, while the A7C uses SDXC or Memory Stick PRO Duo cards. The A7C 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).
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 Pentax K-70 and Sony Alpha A7C and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7C has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The K-70 lacks such a headphone port.
The A7C is a recent model that features in the current product line-up of Sony. In contrast, the K-70 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the K-70 from Pentax. Further information on the features and operation of the K-70 and A7C can be found, respectively, in the Pentax K-70 Manual (free pdf) or the online Sony A7C Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Pentax K-70 or the Sony A7C – 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.
Advantages of the Pentax K-70:
- 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 modern: Reflects 4 years and 3 months of technical progress since the K-70 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the A7C is the clear winner of the contest (21 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.
How about other alternatives? Do the specifications of the Pentax K-70 and the Sony A7C place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the K-70 or the A7C. 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
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 (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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available. |
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 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.
