The camera’s price is obviously a critical decision-making factor. 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 X100F was launched at a somewhat lower price (by 24 percent) than the RX10 IV, which makes it more attractive for photographers on a tight budget. 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 X100F vs Sony RX10 IV

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. 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 Fujifilm X100F features an APS-C sensor and the Sony RX10 IV an one-inch sensor. The sensor area in the RX10 IV 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.

Fujifilm X100F and Sony RX10 IV sensor measures

With 24MP, the X100F offers a higher resolution than the RX10 IV (20MP), but the X100F nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a somewhat more recent model (by 7 months) than the X100F, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X100F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The RX10 IV is equipped with a zoom lens, while the X100F comes with a build-in prime. The RX10 IV has a 24-600mm f/2.4-4.0 optic and the X100F offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Fujifilm. The X100F offers the faster maximum aperture.

Both the X100F and the RX10 IV are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X100F replaced the earlier Fujifilm X100T, while the RX10 IV followed on from the Sony RX10 III.

Review summary: Fujifilm X100F vs Sony RX10 IV

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X100F or the Sony RX10 IV – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Fujifilm X100F:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.4).
  • More compact: Is smaller (127x75mm vs 133x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 626g or 57 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2017).

ilogo

Arguments in favor of the Sony Cyber-shot DSC-RX10 IV:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (24 vs 8 flaps/sec) to capture the decisive moment.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (7 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 IV emerges as the winner of the match-up (11 : 9 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.

X100F 09:11 RX10 IV

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X100F and the RX10 IV 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 expert reviews 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).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
