Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-3N and the Sony Cyber-shot DSC-RX0? 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 NEX-3N and the Sony RX0 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 width, height and depth measures are rounded to the nearest millimeter.

The NEX-3N can be obtained in two different colors (black, white), while the RX0 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 RX0 is considerably smaller (65 percent) than the Sony NEX-3N. It is noteworthy in this context that the RX0 is splash and dust-proof, while the NEX-3N does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 has a lens built in, whereas the NEX-3N 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-3N and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the NEX-3N gets 480 shots out of its Sony NP-FW50 battery, while the RX0 can take 240 images on a single charge of its Sony NP-BJ1 power pack. The power pack in the RX0 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.

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. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 NEX-3N features an APS-C sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 is 68 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the RX0 uses a more advanced image processing engine (BIONZ X) than the NEX-3N (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

With 16MP, the NEX-3N offers a slightly higher resolution than the RX0 (15.4MP), but the NEX-3N nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 2.74μm for the RX0) due to its larger sensor. However, the RX0 is a much more recent model (by 4 years and 6 months) than the NEX-3N, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Sony Alpha NEX-3N has a native sensitivity range from ISO 200 to ISO 16000. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 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 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. Of the two cameras under review, the NEX-3N has a notably higher overall DXO score than the RX0 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.1 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 RX0 provides a faster frame rate than the NEX-3N. It can shoot movie footage at 1080/60p, while the NEX-3N is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The NEX-3N and the RX0 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the NEX-3N 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 NEX-3N, the Sony RX0, and comparable cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The NEX-3N has one, while the RX0 does not. While the built-in flash of the NEX-3N is not very powerful, it can at times be useful as a fill-in light.

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 RX0 only has 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 NEX-3N writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the RX0 uses micro SDXC or Memory Stick Micro cards. The RX0 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3N 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 Alpha NEX-3N and Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the NEX-3N does not provide wifi capability.

Both the NEX-3N and the RX0 have been discontinued, but can regularly be found used on ebay. The NEX-3N was replaced by the Sony A5000, while the RX0 was followed by the Sony RX0 II. Further information on the features and operation of the NEX-3N and RX0 can be found, respectively, in the Sony NEX-3N Manual (free pdf) or the online Sony RX0 Manual.

Review summary

So how do things add up? Which of the two cameras – the Sony NEX-3N or the Sony RX0 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Sony Alpha NEX-3N:

• Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (480 versus 240) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More heavily discounted: Has been available for much longer (launched in February 2013).

Arguments in favor of the Sony Cyber-shot DSC-RX0:

• Better jpgs: Has a more modern image processing engine (BIONZ X vs BIONZ).
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Faster burst: Shoots at higher frequency (5.5 vs 4 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has an integrated lens, whereas the NEX-3N necessitates an extra lens.
• More compact: Is smaller (59x41mm vs 110x62mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the NEX-3N).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 6 months of technical progress since the NEX-3N launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX0 is the clear winner of the contest (15 : 11 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 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 Sony NEX-3N and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 NEX-3N and the RX0 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

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], 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 review scores listed above should be treated with care, 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.
