Canon G3 X versus Canon G1 X Mark III

The Canon PowerShot G3 X and the Canon PowerShot G1 X Mark III are two digital cameras that were revealed to the public, respectively, in June 2015 and October 2017. Both the G3X and the G1X Mark III are fixed lens compact cameras that are based on an one-inch (G3X) and an APS-C (G1X Mark III) sensor. The G3X has a resolution of 20 megapixel, whereas the G1X Mark III 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: Canon G3 X vs Canon G1 X Mark III

The physical size and weight of the Canon G3 X and the Canon G1 X Mark III are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

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 G3X 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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison: Canon G3 X vs Canon G1 X Mark III

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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G3 X 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.

Canon G3 X and Canon G1 X Mark III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the G3X (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G3X) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 2 years and 3 months) than the G3X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon G3 X vs Canon G1 X Mark III

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G3 X, the Canon G1 X Mark III, and comparable cameras.

Both the G3X and the G1X Mark III have zoom lenses build in. The G3X has a 24-600mm f/2.8-5.6 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the G3X and G1X Mark III provide the same view at the wide-angle end, but the G1X Mark III has less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Both the G3X 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 G1X Mark III replaced the earlier Canon G1 X Mark II, while the G3X does not have a direct predecessor.

G3X 07:07 G1X Mark III

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 G3X and the G1X Mark III in practical situations. 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 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 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
