Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix A and the Sony Cyber-shot DSC-RX100? 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 Nikon Coolpix A and the Sony RX100 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 Coolpix A can be obtained in two different colors (black, silver), while the RX100 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 RX100 is notably smaller (17 percent) than the Nikon Coolpix A. Moreover, the RX100 is markedly lighter (20 percent) than the Coolpix A. In this context, it is worth noting that neither the Coolpix A nor the RX100 are weather-sealed.

Concerning battery life, the Coolpix A gets 230 shots out of its Nikon EN-EL20 battery, while the RX100 can take 330 images on a single charge of its Sony NP-BX1 power pack. The power pack in the RX100 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 RX100 was launched at a markedly lower price (by 41 percent) than the Coolpix A, which puts it into a different market segment. 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Nikon Coolpix A features an APS-C sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 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.

Despite having a smaller sensor, the RX100 offers a higher resolution of 20 megapixels, compared with 16.1 MP of the Coolpix A. 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 2.41μm versus 4.78μm for the Coolpix A). Moreover, it should be noted that the Coolpix A is a somewhat more recent model (by 8 months) than the RX100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the Coolpix A has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Nikon Coolpix A are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Nikon Coolpix A has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The Sony Cyber-shot DSC-RX100 offers exactly the same ISO settings.

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"). Of the two cameras under review, the Coolpix A provides substantially higher image quality than the RX100, with an overall score that is 14 points higher. This advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, and 1.6 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX100 provides a faster frame rate than the Coolpix A. It can shoot movie footage at 1080/60p, while the Nikon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The Coolpix A and the RX100 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 Coolpix A can be equipped with an optional viewfinder – the DF-CP1. The table below summarizes some of the other core capabilities of the Nikon Coolpix A and Sony RX100 in connection with corresponding information for a sample of similar cameras.

The Nikon Coolpix A has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The RX100 is equipped with a zoom lens, while the Coolpix A comes with a built-in prime. The RX100 has a 28-100mm f/1.8-4.9 optic and the Coolpix A offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Nikon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 offers the faster maximum aperture.

The Coolpix A writes its imaging data to SDXC cards, while the RX100 uses 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 Nikon Coolpix A and Sony Cyber-shot DSC-RX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Coolpix A has a hotshoe, while the RX100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the Coolpix A and the RX100 have been discontinued, but can regularly be found used on ebay. The RX100 was replaced by the Sony RX100 II, while the Coolpix A does not have a direct successor. Further information on the features and operation of the Coolpix A and RX100 can be found, respectively, in the Nikon Coolpix A Manual (free pdf) or the online Sony RX100 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon Coolpix A and the Sony RX100? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Nikon Coolpix A:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (1.4 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Is somewhat more recent (announced 8 months after the RX100).

Advantages of the Sony Cyber-shot DSC-RX100:

• More detail: Has more megapixels (20 vs 16.1MP), which boosts linear resolution by 11%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• More detailed LCD: Has a higher resolution rear screen (1229k vs 921k dots).
• Faster burst: Shoots at higher frequency (10 vs 4 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• More compact: Is smaller (102x58mm vs 111x64mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 59g or 20 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (330 versus 230) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced into a lower priced category (41 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in June 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 is the clear winner of the contest (13 : 8 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 Nikon Coolpix A and the Sony RX100 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the Coolpix A and the RX100 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 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.

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

The above review scores should be interpreted 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.
