Sony RX1R II versus Canon G1 X Mark III

The Sony Cyber-shot DSC-RX1R II and the Canon PowerShot G1 X Mark III are two enthusiast cameras that were revealed to the public, respectively, in October 2015 and October 2017. Both the RX1R II and the G1X Mark III are fixed lens compact cameras that are based on a full frame (RX1R II) and an APS-C sensor. The Sony has a resolution of 42.2 megapixel, whereas the Canon provides 24 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX1R II and the Canon G1 X Mark III. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the RX1R II – represents the basis for the calculations 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 G1X Mark III was launched at a markedly lower price (by 61 percent) than the RX1R II, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 RX1R II features a full frame sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 42.2MP, the RX1R II offers a higher resolution than the G1X Mark III (24MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 3.72μm for the G1X Mark III) due to its larger sensor. However, the G1X Mark III is a somewhat more recent model (by 2 years) than the RX1R II, 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 RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 RX1R II and the G1X Mark III are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The following table reports on some other key feature differences and similarities of the Sony RX1R II, the Canon G1 X Mark III, and comparable cameras.

The G1X Mark III is equipped with a zoom lens, while the RX1R II comes with a build-in prime. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the RX1R II offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Sony. The RX1R II offers the faster maximum aperture.

Both the RX1R II 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 RX1R II replaced the earlier Sony RX1R, while the G1X Mark III followed on from the Canon G1 X Mark II.

Summary

So how do things add up? Is there a clear favorite between the Sony RX1R II and the Sony RX1R II? The listing below highlights the relative strengths of the two models.


logo checkmark

Reasons to prefer the Sony Cyber-shot DSC-RX1R II:

  • More detail: Offers more megapixels (42.2 vs 24MP) with a 33% 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.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster shutter: Has a 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/2.8).
  • More compact: Is smaller (113x65mm vs 115x78mm) and thus needs less room in the bag.
  • More heavily discounted: Has been available for much longer (launched in October 2015).

logo checkmark

Arguments in favor of the Canon PowerShot G1 X Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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.
  • Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Less heavy: Has a lower weight (by 108g or 21 percent) and is thus easier to take along.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the RX1R II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark III emerges as the winner of the match-up (10 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points.

RX1R II 08:10 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 RX1R II or the G1X Mark III 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 following table reports the overall rankings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
