Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark II and the Sony Cyber-shot DSC-H400? 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

An illustration of the physical size and weight of the Olympus E-M10 II and the Sony H400 is provided 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 II can be obtained in three different colors (black, silver, brown), while the H400 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 H400 is notably larger (24 percent) than the Olympus E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the H400 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the H400 has a lens built in, whereas the E-M10 II 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 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 II gets 320 shots out of its Olympus BLS-50 battery, while the H400 can take 300 images on a single charge of its Sony NP-BX1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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. The H400 was launched at a lower price than the E-M10 II, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-M10 II features a Four Thirds sensor and the Sony H400 a 1/2.3-inch sensor. The sensor area in the H400 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 H400 offers a higher resolution of 19.9 megapixels, compared with 15.9 MP of the E-M10 II. 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 1.19μm versus 3.76μm for the E-M10 II). Moreover, it should be noted that the E-M10 II is a somewhat more recent model (by 1 year and 6 months) than the H400, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 H400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the H400 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Olympus E-M10 II 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 II 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-H400 are ISO 80 to ISO 3200 (no boost).

In terms of underlying technology, the E-M10 II is build around a CMOS sensor, while the H400 uses a CCD 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M10 II provides a higher video resolution than the H400. It can shoot video footage at 1080/60p, while the Sony is limited to 720/30p.

Feature comparison

Apart from 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 II offers a substantially higher resolution than the one in the H400 (2360k vs 210k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 II has a touchscreen, while the H400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 E-M10 II 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 Olympus E-M10 II 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 II writes its imaging data to SDXC cards, while the H400 uses SDXC or Memory Stick PRO Duo cards. The E-M10 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the H400 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 Mark II and Sony Cyber-shot DSC-H400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 II has a hotshoe, while the H400 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the E-M10 II and the H400 have been discontinued, but can regularly be found used on ebay. The E-M10 II was replaced by the Olympus E-M10 III, while the H400 does not have a direct successor. Further information on the features and operation of the E-M10 II and H400 can be found, respectively, in the Olympus E-M10 II Manual (free pdf) or the online Sony H400 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-M10 II or the Sony H400 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Olympus OM-D E-M10 Mark II:

• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 210k dots).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 0.7 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• 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 (120x83mm vs 130x95mm) and thus needs less room in the bag.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Is somewhat more recent (announced 1 year and 6 months after the H400).

Arguments in favor of the Sony Cyber-shot DSC-H400:

• More detail: Has more megapixels (19.9 vs 15.9MP), which boosts linear resolution by 12%.
• Ready to shoot: Has an integrated lens, whereas the E-M10 II necessitates an extra lens.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in February 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 II is the clear winner of the match-up (18 : 4 points). 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 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 II and the Sony H400 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 II or the H400. 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 where reviews by experts come in. 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
