Sony RX100 versus Sony RX1

The Sony Cyber-shot DSC-RX100 and the Sony Cyber-shot DSC-RX1 are two digital cameras that were officially introduced, respectively, in June 2012 and September 2012. Both the RX100 and the RX1 are fixed lens compact cameras that are based on an one-inch (RX100) and a full frame sensor. The RX100 has a resolution of 20 megapixel, whereas the RX1 provides 24 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX100 and the Sony RX1. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX100 – represents 100 percent across all the size and weight measures).

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 was launched at a markedly lower price (by 77 percent) than the RX1, 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 imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX100 features an one-inch sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 634 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the RX1 offers a higher resolution than the RX100 (20MP), but the RX1 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 2.41μm for the RX100) due to its larger sensor. Moreover, the RX1 is a somewhat more recent model (by 3 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 pixel-units.

RX100 versus RX1 MP
Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 RX1 offers substantially better image quality than the RX100 (overall score 27 points higher). The advantage is based on 2.5 bits higher color depth, 1.9 EV in additional dynamic range, and 2.7 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The RX100 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. The following table reports on some other key feature differences and similarities of the Sony RX100, the Sony RX1, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The RX100 is equipped with a zoom lens, while the RX1 comes with a build-in prime. The RX100 has a 28-100mm f/1.8-4.9 optic and the RX1 offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the RX100 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the RX1. The RX100 offers the faster maximum aperture.

Both the RX100 and the RX1 have been discontinued, but can regularly be found used on ebay. The RX100 was replaced by the Sony RX100 II, while the RX1 was followed by the Sony RX1R.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Sony RX100 and the Sony RX100? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Sony Cyber-shot DSC-RX100:

  • Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (102x58mm vs 113x65mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 242g or 50 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (330 versus 270) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2012).

Reasons to prefer the Sony Cyber-shot DSC-RX1:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.7 stops ISO advantage).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More modern: Was introduced somewhat (3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the RX100 emerges as the winner of the contest (9 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the RX100 or the RX1 handle or perform in practice. 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
