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-HX90V? 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 and the Sony HX90V 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 measures are rounded to the nearest millimeter.

The E-M10 can be obtained in two different colors (black, silver), while the HX90V 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 HX90V is considerably smaller (39 percent) than the Olympus E-M10. In this context, it is worth noting that neither the E-M10 nor the HX90V are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX90V 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 HX90V can take 360 images on a single charge of its Sony NP-BX1 power pack. The power pack in the HX90V 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. 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 naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The HX90V was launched at a lower price than the E-M10, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Olympus E-M10 features a Four Thirds sensor and the Sony HX90V a 1/2.3-inch sensor. The sensor area in the HX90V 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 HX90V offers a higher resolution of 18 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 1.25μm versus 3.76μm for the E-M10). However, it should be noted that the HX90V is a somewhat more recent model (by 1 year and 2 months) than the E-M10, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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 HX90V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX90V for good quality output (200 dots per inch) amounts to 24.5 x 18.4 inches or 62.2 x 46.6 cm, for very good quality (250 dpi) 19.6 x 14.7 inches or 49.7 x 37.3 cm, and for excellent quality (300 dpi) 16.3 x 12.2 inches or 41.5 x 31.1 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-HX90V 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 HX90V 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 HX90V 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

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 offers a substantially higher resolution than the one in the HX90V (1440k vs 638k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M10, the Sony HX90V, 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 HX90V 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 HX90V uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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-HX90V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 has a hotshoe, while the HX90V does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Travel and landscape photographers will find it useful that the HX90V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the E-M10 and the HX90V have been discontinued, but can regularly be found used on ebay. The E-M10 was replaced by the Olympus E-M10 II, while the HX90V was followed by the Sony HX99. Further information on the features and operation of the E-M10 and HX90V can be found, respectively, in the Olympus E-M10 Manual (free pdf) or the online Sony HX90V Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-M10 and the Sony HX90V? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

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 638k 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.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• 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.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been on the market for longer (launched in January 2014).

Arguments in favor of the Sony Cyber-shot DSC-HX90V:

• More detail: Has more megapixels (18 vs 15.9MP), which boosts linear resolution by 6%.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• 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.
• More compact: Is smaller (102x58mm vs 119x82mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the E-M10).
• Longer lasting: Gets more shots (360 versus 320) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the HX90V comes out slightly ahead of the E-M10 (13 : 12 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 Olympus E-M10 and the Sony HX90V 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 HX90V. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
