Fujifilm X70 vs Olympus E-M10 IV
The Fujifilm X70 and the Olympus OM-D E-M10 Mark IV are two digital cameras that were officially introduced, respectively, in January 2016 and August 2020. The X70 is a fixed lens compact, while the E-M10 IV is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (X70) and a Four Thirds (E-M10 IV) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Olympus provides 20.2 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 Fujifilm X70 and the Olympus OM-D E-M10 Mark 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.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X70 and the Olympus E-M10 IV. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth 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 Olympus E-M10 IV is notably larger (42 percent) than the Fujifilm X70. In this context, it is worth noting that neither the X70 nor the E-M10 IV are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X70 has a lens built in, whereas the E-M10 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 E-M10 IV and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the X70 gets 330 shots out of its NP-95 battery, while the E-M10 IV can take 360 images on a single charge of its BLS-50 power pack. The battery packs of both cameras can be charged via USB, 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.

Any camera decision will obviously take relative prices into account. 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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X70 features an APS-C sensor and the Olympus E-M10 IV a Four Thirds sensor. The sensor area in the E-M10 IV is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X70 has a native 3:2 aspect ratio, while the one in the E-M10 IV offers a 4:3 aspect.
Despite having a smaller sensor, the E-M10 IV offers a higher resolution of 20.2 megapixels, compared with 16 MP of the X70. 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 3.34μm versus 4.80μm for the X70). However, it should be noted that the E-M10 IV is much more recent (by 4 years and 6 months) than the X70, 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 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 Olympus E-M10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 IV for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Fujifilm X70 are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.
The X70 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X70 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus OM-D E-M10 Mark IV are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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 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, but the E-M10 IV provides a better video resolution than the X70. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 IV has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X70 relies on live view and the rear LCD for framing. That said, the X70 can be equipped with an optional viewfinder – the VF-X21. The following table reports on some other key feature differences and similarities of the Fujifilm X70, the Olympus E-M10 IV, and comparable cameras.

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 Fujifilm X70 and the Olympus E-M10 IV 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.
Concerning the storage of imaging data, both the X70 and the E-M10 IV write their files to SDXC cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X70 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 Fujifilm X70 and Olympus OM-D E-M10 Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X70 has a microphone port, which is missing on the E-M10 IV. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the X70 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the X70 was succeeded by the Fujifilm XF10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Olympus websites.
So how do things add up? Is the Fujifilm X70 better than the Olympus E-M10 IV or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Fujifilm X70:
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Ready to shoot: Has a lens built-in, whereas the E-M10 IV requires a separate lens.
- More compact: Is smaller (113x64mm vs 122x84mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M10 IV).
- More heavily discounted: Has been available for much longer (launched in January 2016).
Reasons to prefer the Olympus OM-D E-M10 Mark IV:
- More detail: Has more megapixels (20.2 vs 16MP), which boosts linear resolution by 10%.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster burst: Shoots at higher frequency (15 vs 8 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 4 years and 6 months of technical progress since the X70 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 IV emerges as the winner of the match-up (9 : 6 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 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 Fujifilm X70 and the Olympus E-M10 IV place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X70 and the E-M10 IV in practical situations. 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
