Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-5 and the Sony Cyber-shot DSC-RX1? 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 Sony NEX-5 and the Sony RX1 is provided in the side-by-side display below. 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-5 can be obtained in two different colors (black, silver), while the RX1 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 RX1 is notably larger (12 percent) than the Sony NEX-5. In this context, it is worth noting that neither the NEX-5 nor the RX1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1 has a lens built in, whereas the NEX-5 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-5 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the NEX-5 gets 330 shots out of its Sony NP-FW50 battery, while the RX1 can take 270 images on a single charge of its Sony NP-BX1 power pack. The power pack in the RX1 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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-5 features an APS-C sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the RX1 uses a more advanced image processing engine (BIONZ X) than the NEX-5 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

With 24MP, the RX1 offers a higher resolution than the NEX-5 (14MP), but the RX1 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 5.11μm for the NEX-5) due to its larger sensor. Moreover, the RX1 is a much more recent model (by 2 years and 4 months) than the NEX-5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony RX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony NEX-5 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 Alpha NEX-5 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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.

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"). Of the two cameras under consideration, the RX1 offers substantially better image quality than the NEX-5 (overall score 24 points higher). The advantage is based on 2.9 bits higher color depth, 2.1 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX1 provides a faster frame rate than the NEX-5. It can shoot movie footage at 1080/60p, while the NEX-5 is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The NEX-5 and the RX1 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. However, optional viewfinders – the FDA-SV1 for the NEX-5 and the FDA-EV1MK for the RX1 – are available as accessories. The following table reports on some other key feature differences and similarities of the Sony NEX-5, the Sony RX1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The RX1 has one, while the NEX-5 does not. While the built-in flash of the RX1 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the NEX-5 and the RX1 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 Alpha NEX-5 and Sony Cyber-shot DSC-RX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The NEX-5 does not feature such a mic input.

Both the NEX-5 and the RX1 have been discontinued, but can regularly be found used on ebay. The NEX-5 was replaced by the Sony NEX-5N, while the RX1 was followed by the Sony RX1R. Further information on the features and operation of the NEX-5 and RX1 can be found, respectively, in the Sony NEX-5 Manual (free pdf) or the online Sony RX1 Manual.

Review summary

So what is the bottom line? Is the Sony NEX-5 better than the Sony RX1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Sony Alpha NEX-5:

• 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.
• Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More compact: Is smaller (111x59mm vs 113x65mm) and thus needs less room in the bag.
• Longer lasting: Can take more shots (330 versus 270) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in May 2010).

Arguments in favor of the Sony Cyber-shot DSC-RX1:

• More detail: Has more megapixels (24 vs 14MP), which boosts linear resolution by 31%.
• Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.9 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.7 stops ISO advantage).
• 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.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 920k dots).
• Ready to shoot: Has an integrated lens, whereas the NEX-5 necessitates an extra lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More modern: Reflects 2 years and 4 months of technical progress since the NEX-5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the RX1 is the clear winner of the contest (13 : 7 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 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 NEX-5 and the Sony RX1 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the NEX-5 or the RX1. 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 expert reviews 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
