Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-HX400V and the Sony Alpha NEX-3? 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 Sony HX400V and the Sony NEX-3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The NEX-3 can be obtained in three different colors (black, silver, red), 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 NEX-3 is considerably smaller (40 percent) than the Sony HX400V. In this context, it is worth noting that neither the HX400V nor the NEX-3 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 NEX-3 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 NEX-3 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the HX400V gets 300 shots out of its NP-BX1 battery, while the NEX-3 can take 330 images on a single charge of its NP-FW50 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 HX400V was launched at a lower price than the NEX-3, 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. 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 Sony HX400V features a 1/2.3-inch sensor and the Sony NEX-3 an APS-C sensor. The sensor area in the NEX-3 is 1204 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the HX400V has a native 4:3 aspect ratio, while the one in the NEX-3 offers a 3:2 aspect.

In terms of chip-set technology, the HX400V uses a more advanced image processing engine (BIONZ X) than the NEX-3 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the Sony HX400V offers a higher resolution of 20.2 megapixels, compared with 14 MP of the Sony NEX-3. 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 5.11μm for the NEX-3). However, it should be noted that the HX400V is much more recent (by 3 years and 9 months) than the NEX-3, 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 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 Sony NEX-3 are 23 x 15.3 inches or 58.3 x 38.8 cm for good quality, 18.4 x 12.2 inches or 46.7 x 31 cm for very good quality, and 15.3 x 10.2 inches or 38.9 x 25.9 cm for excellent quality prints.

The Sony Cyber-shot DSC-HX400V has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).

In terms of underlying technology, the HX400V is build around a BSI-CMOS sensor, while the NEX-3 uses a 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 HX400V provides a higher video resolution than the NEX-3. It can shoot video footage at 1080/60p, while the NEX-3 is limited to 720/30p.

Feature comparison

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 NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The table below summarizes some of the other core capabilities of the Sony HX400V and Sony NEX-3 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The HX400V has one, while the NEX-3 does not. While the built-in flash of the HX400V is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the HX400V and the NEX-3 write their files to SDXC or Memory Stick PRO Duo 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 Sony Cyber-shot DSC-HX400V and Sony Alpha NEX-3 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, while the NEX-3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

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 HX400V and the NEX-3 have been discontinued, but can regularly be found used on ebay. The NEX-3 was replaced by the Sony NEX-3N, while the HX400V does not have a direct successor. Further information on the features and operation of the HX400V and NEX-3 can be found, respectively, in the Sony HX400V Manual (free pdf) or the online Sony NEX-3 Manual.

Review summary

So how do things add up? Is the Sony HX400V better than the Sony NEX-3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Sony Cyber-shot DSC-HX400V:

• More detail: Offers more megapixels (20.2 vs 14MP) with a 17% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (BIONZ X vs BIONZ).
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the NEX-3 requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• 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: Reflects 3 years and 9 months of technical progress since the NEX-3 launch.

Advantages of the Sony Alpha NEX-3:

• 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.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (117x62mm vs 130x93mm) and will fit more readily into a bag.
• More heavily discounted: Has been around for much longer (launched in May 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the HX400V is the clear winner of the match-up (14 : 9 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 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 Sony HX400V and the Sony NEX-3 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 HX400V and the NEX-3 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. 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 review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
