Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-HX99 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 side-by-side display below illustrates the physical size and weight of the Sony HX99 and the Sony NEX-3. 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 measures are rounded to the nearest millimeter.

The NEX-3 can be obtained in three different colors (black, silver, red), while the HX99 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 notably larger (23 percent) than the Sony HX99. In this context, it is worth noting that neither the HX99 nor the NEX-3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX99 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 HX99 gets 370 shots out of its Sony NP-BX1 battery, while the NEX-3 can take 330 images on a single charge of its Sony NP-FW50 power pack. The power pack in the HX99 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The HX99 was launched at a lower price than the NEX-3, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony HX99 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 HX99 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 HX99 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 HX99 offers a higher resolution of 18 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 1.25μm versus 5.11μm for the NEX-3). However, it should be noted that the HX99 is much more recent (by 8 years and 3 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 HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony HX99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX99 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 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-HX99 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 HX99 provides a higher video resolution than the NEX-3. It can shoot video footage at 4K/30p, while the NEX-3 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the HX99 has an electronic viewfinder (638k 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 following table reports on some other key feature differences and similarities of the Sony HX99, the Sony NEX-3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The HX99 has one, while the NEX-3 does not. While the built-in flash of the HX99 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the HX99 and the NEX-3 write their files to SDXC or Memory Stick PRO Duo cards. The HX99 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3 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 Sony Cyber-shot DSC-HX99 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 HX99 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.

Both the HX99 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 HX99 does not have a direct successor. Further information on the features and operation of the HX99 and NEX-3 can be found, respectively, in the Sony HX99 Manual (free pdf) or the online Sony NEX-3 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Sony HX99 and the Sony NEX-3? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Sony Cyber-shot DSC-HX99:

• More detail: Offers more megapixels (18 vs 14MP) with a 11% 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 (4K/30p vs 720/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• 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.
• More compact: Is smaller (102x58mm vs 117x62mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the NEX-3).
• Longer lasting: Can take more shots (370 versus 330) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.

• More modern: Reflects 8 years and 3 months of technical progress since the NEX-3 launch.

Reasons to prefer 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.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in May 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the HX99 is the clear winner of the match-up (20 : 9 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 Sony HX99 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 HX99 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
