Olympus E-M10 III vs Sony ZV-1
The Olympus OM-D E-M10 Mark III and the Sony Cyber-shot ZV-1 are two digital cameras that were officially introduced, respectively, in August 2017 and May 2020. The E-M10 III is a mirrorless interchangeable lens camera, while the ZV-1 is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 III) and an one-inch (ZV-1) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 20 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 Olympus OM-D E-M10 Mark III and the Sony Cyber-shot ZV-1? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M10 III and the Sony ZV-1. 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 E-M10 III can be obtained in two different colors (black, silver), while the ZV-1 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 ZV-1 is considerably smaller (39 percent) than the Olympus E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the ZV-1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZV-1 has a lens built in, whereas the E-M10 III 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 E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-M10 III gets 330 shots out of its BLS-50 battery, while the ZV-1 can take 260 images on a single charge of its NP-BX1 power pack. The power pack in the ZV-1 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 Olympus E-M10 III features a Four Thirds sensor and the Sony ZV-1 an one-inch sensor. The sensor area in the ZV-1 is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-M10 III has a native 4:3 aspect ratio, while the one in the ZV-1 offers a 3:2 aspect.
Despite having a smaller sensor, the ZV-1 offers a higher resolution of 20 megapixels, compared with 15.9 MP of the E-M10 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 2.41μm versus 3.76μm for the E-M10 III). However, it should be noted that the ZV-1 is much more recent (by 2 years and 8 months) than the E-M10 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 E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony ZV-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZV-1 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M10 III are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Olympus OM-D E-M10 Mark III has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Cyber-shot ZV-1 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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"). 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 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, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the ZV-1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-M10 III and Sony ZV-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-M10 III has one, while the ZV-1 does not. While the built-in flash of the E-M10 III is not very powerful, it can at times be useful as a fill-in light.The ZV-1 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 E-M10 III 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 Olympus E-M10 III and the Sony ZV-1 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 E-M10 III writes its imaging data to SDXC cards, while the ZV-1 uses SDXC or Memory Stick PRO Duo cards. The E-M10 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the ZV-1 can use UHS-I cards (up to 104 MB/s).
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 Olympus OM-D E-M10 Mark III and Sony Cyber-shot ZV-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the ZV-1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 III does not feature such a mic input.
The ZV-1 is a recent model that features in the current product line-up of Sony. In contrast, the E-M10 III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 III was succeeded by the Olympus E-M10 IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.
So what conclusions can be drawn? Is the Olympus E-M10 III better than the Sony ZV-1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Olympus OM-D E-M10 Mark III:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

- More modern: Reflects 2 years and 8 months of technical progress since the E-M10 III launch.
If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (13 points each). 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 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 Olympus E-M10 III and the Sony ZV-1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M10 III or the ZV-1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
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], 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. 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.
