Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha NEX-7 and the Sony Cyber-shot DSC-RX1R II? 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 NEX-7 and the Sony RX1R II. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R II is notably smaller (9 percent) than the Sony NEX-7. In this context, it is worth noting that neither the NEX-7 nor the RX1R II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R II has a lens built in, whereas the NEX-7 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-7 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the NEX-7 gets 430 shots out of its Sony NP-FW50 battery, while the RX1R II can take 220 images on a single charge of its Sony NP-BX1 power pack. The power pack in the RX1R II 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. 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.

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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony NEX-7 features an APS-C sensor and the Sony RX1R II a full frame sensor. The sensor area in the RX1R II is 135 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 RX1R II uses a more advanced image processing engine (BIONZ X) than the NEX-7 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

With 42.2MP, the RX1R II offers a higher resolution than the NEX-7 (24MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 3.90μm for the NEX-7) due to its larger sensor. Moreover, the RX1R II is a much more recent model (by 4 years and 1 month) than the NEX-7, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Sony NEX-7 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Sony Alpha NEX-7 has a native sensitivity range from ISO 100 to ISO 16000. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the NEX-7 is build around a CMOS sensor, while the RX1R II uses a BSI-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 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"). Of the two cameras under consideration, the RX1R II offers substantially better image quality than the NEX-7 (overall score 16 points higher). The advantage is based on 1.7 bits higher color depth, 0.5 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. 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 RX1R II provides a faster frame rate than the NEX-7. It can shoot movie footage at 1080/60p, while the NEX-7 is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the RX1R II offers a slightly higher resolution than the one in the NEX-7 (2360k vs 2359k dots). The adjacent table lists some of the other core features of the Sony NEX-7 and Sony RX1R II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The NEX-7 has one, while the RX1R II does not. While the built-in flash of the NEX-7 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the NEX-7 and the RX1R II write their files to SDXC or Memory Stick PRO Duo cards. The RX1R II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-7 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-7 and Sony Cyber-shot DSC-RX1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1R II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the NEX-7 does not provide wifi capability.

Both the NEX-7 and the RX1R II have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Sony. Further information on the features and operation of the NEX-7 and RX1R II can be found, respectively, in the Sony NEX-7 Manual (free pdf) or the online Sony RX1R II Manual.

Review summary

So what conclusions can be drawn? Is the Sony NEX-7 better than the Sony RX1R II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Sony Alpha NEX-7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Longer lasting: Can take more shots (430 versus 220) 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 August 2011).

Arguments in favor of the Sony Cyber-shot DSC-RX1R II:

• More detail: Has more megapixels (42.2 vs 24MP), which boosts linear resolution by 33%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
• 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).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.73x).
• More detailed LCD: Has a higher resolution rear screen (1229k vs 921k dots).
• Ready to shoot: Has an integrated lens, whereas the NEX-7 necessitates an extra lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 1 month of technical progress since the NEX-7 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the RX1R II is the clear winner of the contest (15 : 6 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 NEX-7 and the Sony RX1R II 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 remains incomplete and does no justice, for example, to the way the NEX-7 or the RX1R II perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
