The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 V was launched at a somewhat lower price (by 23 percent) than the G1X Mark III, 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

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. 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 Sony RX100 V features an one-inch sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the G1X Mark III offers a higher resolution than the RX100 V (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX100 V) due to its larger sensor. Moreover, the G1X Mark III is a somewhat more recent model (by 1 year) than the RX100 V, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

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 RX100 V provides a higher video resolution than the G1X Mark III. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Beyond 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 G1X Mark III offers a slightly higher resolution than the one in the RX100 V (2360k vs 2359k dots). The adjacent table lists some of the other core features of the Sony RX100 V and Canon G1 X Mark III along with similar information for a selection of comparators.

Both the RX100 V and the G1X Mark III have zoom lenses build in. The RX100 V has a 24-70mm f/1.8-2.8 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the Sony and Canon provide the same view at the wide-angle end, but the Canon has more tele-photo reach at the long end. The RX100 V offers the faster maximum aperture.

Both the RX100 V and the G1X Mark III are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The RX100 V replaced the earlier Sony RX100 IV, while the G1X Mark III followed on from the Canon G1 X Mark II.

Summary

So what conclusions can be drawn? Is the Sony RX100 V better than the Canon G1 X Mark III or vice versa? The listing below highlights the relative strengths of the two models.


logo checkmark

Reasons to prefer the Sony Cyber-shot DSC-RX100 V:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (24 vs 9 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 115x78mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 100g or 25 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (23 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2016).

Advantages of the Canon PowerShot G1 X Mark III:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 V comes out slightly ahead of the G1X Mark III (8 : 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.

RX100 V 08:07 G1X Mark III

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 V or the G1X Mark III handle or 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
