Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-ZS70 and the Sony Alpha A7R IV? 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 Panasonic ZS70 and the Sony A7R IV 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 ZS70 can be obtained in two different colors (black, silver), while the A7R IV 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 Sony A7R IV is considerably larger (65 percent) than the Panasonic ZS70. It is noteworthy in this context that the A7R IV is splash and dust-proof, while the ZS70 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZS70 has a lens built in, whereas the A7R IV is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A7R IV and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the ZS70 gets 380 shots out of its DMW-BLG10 battery, while the A7R IV can take 670 images on a single charge of its NP-FZ100 power pack. The battery packs of both cameras can be charged via USB, 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 ZS70 was launched at a lower price than the A7R IV, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic ZS70 features a 1/2.3-inch sensor and the Sony A7R IV a full frame sensor. The sensor area in the A7R IV is 2936 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the ZS70 has a native 4:3 aspect ratio, while the one in the A7R IV offers a 3:2 aspect.
With 60.2MP, the A7R IV offers a higher resolution than the ZS70 (20.2MP), but the A7R IV nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.18μm for the ZS70) due to its larger sensor. Moreover, the A7R IV is a much more recent model (by 2 years and 2 months) than the ZS70, 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 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 Sony A7R IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IV for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Panasonic ZS70 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
The A7R IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the ZS70, the A7R IV has the capacity to capture high quality composite images (241MP) 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 Panasonic Lumix DC-ZS70 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Sony Alpha A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R IV offers a substantially higher resolution than the one in the ZS70 (5760k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Panasonic ZS70, the Sony A7R IV, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The ZS70 has one, while the A7R IV does not. While the built-in flash of the ZS70 is not very powerful, it can at times be useful as a fill-in light.The ZS70 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A7R IV does not have a selfie-screen.
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, both cameras under consideration feature an 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 Sony A7R IV 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.
Concerning the storage of imaging data, both the ZS70 and the A7R IV write their files to SDXC cards. The A7R IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the ZS70 only has one slot. The A7R IV supports UHS-II cards (on both slots), while the ZS70 can use UHS-I cards.
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 Panasonic Lumix DC-ZS70 and Sony Alpha A7R IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IV has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The ZS70 does not feature such a mic input.
Studio photographers will appreciate that the Sony A7R IV (unlike the ZS70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The A7R IV is a recent model that features in the current product line-up of Sony. In contrast, the ZS70 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the ZS70 was succeeded by the Panasonic ZS80. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R IV is the clear winner of the contest (25 : 7 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Panasonic ZS70 and the Sony A7R IV place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 ZS70 and the A7R IV 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.
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 (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.

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.
