Olympus E-PM2 vs Sony HX400V
The Olympus PEN E-PM2 and the Sony Cyber-shot DSC-HX400V are two digital cameras that were officially introduced, respectively, in September 2012 and February 2014. The E-PM2 is a mirrorless interchangeable lens camera, while the HX400V is a fixed lens compact. The cameras are based on a Four Thirds (E-PM2) and a 1/2.3-inch (HX400V) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony 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 Olympus PEN E-PM2 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-PM2 and the Sony HX400V. 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-PM2 can be obtained in four different colors (black, silver, red, white), 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 considerably larger (72 percent) than the Olympus E-PM2. In this context, it is worth noting that neither the E-PM2 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-PM2 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-PM2 and their specifications in the Micro Four Thirds Lens Catalog.
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. 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. 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 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-PM2 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-PM2. 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-PM2). However, it should be noted that the HX400V is a somewhat more recent model (by 1 year and 4 months) than the E-PM2, 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 the HX400V has no anti-alias filter installed, so that it can capture all the detail its 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-PM2 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 PEN E-PM2 has a native sensitivity range from ISO 100 to ISO 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.
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 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 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, but the HX400V provides a faster frame rate than the E-PM2. It can shoot movie footage at 1080/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the HX400V has an electronic viewfinder (210k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM2 relies on live view and the rear LCD for framing. That said, the E-PM2 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Olympus E-PM2 and Sony HX400V along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-PM2 has a touchscreen, while the HX400V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The E-PM2 writes its imaging data to SDXC cards, while the HX400V uses SDXC or Memory Stick PRO Duo cards. The E-PM2 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.
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 PEN E-PM2 and Sony Cyber-shot DSC-HX400V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the HX400V offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-PM2 does not provide wifi capability.
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.
The HX400V is a recent model that features in the current product line-up of Sony. In contrast, the E-PM2 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-PM2 from Olympus. 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-PM2 better than the Sony HX400V or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Olympus PEN E-PM2:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- 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.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (110x64mm vs 130x93mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (360 versus 300) on a single battery charge.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been on the market for longer (launched in September 2012).
Advantages of the Sony Cyber-shot DSC-HX400V:
- More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

If the count of relative strengths (bullet points above) is taken as a measure, the HX400V emerges as the winner of the match-up (13 : 11 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 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-PM2 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-PM2 and the HX400V in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
