The price is, of course, an important factor in any camera decision. The listed launch 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: Canon G1 X Mark III vs Sony RX100 V

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 65 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.

Canon G1 X Mark III and Sony RX100 V sensor measures

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 pixels.

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

Both the G1X Mark III and the RX100 V 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.

If the count of individual advantages (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 before making a decision on a new camera.

G1X Mark III 07:08 RX100 V

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 G1X Mark III and the RX100 V 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 where reviews by experts come in. 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
