Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 and the Sony Cyber-shot DSC-HX400V? 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 Olympus E-M10 and the Sony HX400V are illustrated in the side-by-side display below. 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.

The E-M10 can be obtained in two different colors (black, silver), while the HX400V 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 HX400V is notably larger (24 percent) than the Olympus E-M10. In this context, it is worth noting that neither the E-M10 nor the HX400V are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX400V has a lens built in, whereas the E-M10 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 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 gets 320 shots out of its Olympus BLS-5 battery, while the HX400V can take 300 images on a single charge of its Sony NP-BX1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The HX400V was launched at a lower price than the E-M10, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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. 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 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 features a Four Thirds sensor and the Sony HX400V a 1/2.3-inch sensor. The sensor area in the HX400V is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the HX400V offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the E-M10. 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 1.18μm versus 3.76μm for the E-M10). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 HX400V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX400V 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 Olympus E-M10 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 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 DSC-HX400V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the E-M10 is build around a CMOS sensor, while the HX400V 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the HX400V provides a faster frame rate than the E-M10. It can shoot movie footage at 1080/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 offers a substantially higher resolution than the one in the HX400V (1440k vs 210k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M10, the Sony HX400V, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 has a touchscreen, while the HX400V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Olympus E-M10 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 E-M10 writes its imaging data to SDXC cards, while the HX400V uses SDXC or Memory Stick PRO Duo cards. The E-M10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the HX400V cannot take advantage of Ultra High Speed SD cards.

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 Olympus OM-D E-M10 and Sony Cyber-shot DSC-HX400V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Travel and landscape photographers will find it useful that the HX400V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the E-M10 and the HX400V have been discontinued, but can regularly be found used on ebay. The E-M10 was replaced by the Olympus E-M10 II, while the HX400V does not have a direct successor. Further information on the features and operation of the E-M10 and HX400V can be found, respectively, in the Olympus E-M10 Manual (free pdf) or the online Sony HX400V Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Olympus E-M10 and the Sony HX400V? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Olympus OM-D E-M10:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 210k dots).
• More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More compact: Is smaller (119x82mm vs 130x93mm) and thus needs less room in the bag.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.

Arguments in favor of the Sony Cyber-shot DSC-HX400V:

• More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has an integrated lens, whereas the E-M10 necessitates an extra lens.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 is the clear winner of the match-up (11 : 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 Olympus E-M10 and the Sony HX400V place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M10 or the HX400V. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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.
