Fujifilm X100 versus Sony RX1

The Fujifilm FinePix X100 and the Sony Cyber-shot DSC-RX1 are two enthusiast cameras that were officially introduced, respectively, in September 2010 and September 2012. Both the X100 and the RX1 are fixed lens compact cameras that are based on an APS-C (X100) and a full frame (RX1) sensor. The Fujifilm has a resolution of 12.2 megapixel, whereas the Sony provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X100 vs Sony RX1

The physical size and weight of the Fujifilm X100 and the Sony RX1 are illustrated 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. 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 X100 – represents 100 percent across all the size and weight measures).

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 smaller (22 percent) than the Fujifilm X100. However, the RX1 is markedly heavier (8 percent) than the X100. In this context, it is worth noting that neither the X100 nor the RX1 are weather-sealed.

Concerning battery life, the X100 gets 300 shots out of its NP-95 battery, while the RX1 can take 270 images on a single charge of its NP-BX1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X100 was launched at a markedly lower price (by 57 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: Fujifilm X100 vs Sony RX1

The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X100 features an APS-C sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 128 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.

Fujifilm X100 and Sony RX1 sensor measures

With 24MP, the RX1 offers a higher resolution than the X100 (12.2MP), but the RX1 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 5.53μm for the X100) due to its larger sensor. Moreover, the RX1 is a somewhat more recent model (by 1 year and 11 months) than the X100, and its sensor might 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 X100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

X100 versus RX1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 X100 (overall score 20 points higher). The advantage is based on 2.2 bits higher color depth, 1.9 EV in additional dynamic range, and 1.3 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 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 RX1 provides a better video resolution than the X100. It can shoot movie footage at 1080/60p, while the Fujifilm is limited to 720/30p.

 

Feature comparison: Fujifilm X100 vs Sony RX1

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X100 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1 relies on live view and the rear LCD for framing. That said, the RX1 can be equipped with an optional viewfinder – the FDA-EV1MK. The following table reports on some other key feature differences and similarities of the Fujifilm X100, the Sony RX1, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

Arguments in favor of the Fujifilm FinePix X100:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Longer lasting: Can take more shots (300 versus 270) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2010).

ilogo

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

  • More detail: Has more megapixels (24 vs 12.2MP), which boosts linear resolution by 40%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 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 (1.3 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
  • More compact: Is smaller (113x65mm vs 126x75mm) and will fit more readily into a bag.
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the RX1 is the clear winner of the contest (12 : 5 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 before making a decision on a new camera.

X100 05:12 RX1

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X100 and the RX1 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
