Canon 1D X Mark II versus Canon G3 X

The Canon EOS-1D X Mark II and the Canon PowerShot G3 X are two digital cameras that were officially introduced, respectively, in February 2016 and June 2015. The 1DX Mark II is a DSLR, while the G3X is a fixed lens compact. The cameras are based on a full frame (1DX Mark II) and an one-inch (G3X) sensor. Both cameras offer a resolution of 20 megapixel. 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 1D X Mark II vs Canon G3 X

The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark II and the Canon G3 X. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 1DX Mark II – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G3 X is considerably smaller (64 percent) than the Canon 1D X Mark II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens build in, whereas the 1DX Mark II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 1DX Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the G3X can take 300 images on a single charge of its NB-10L power pack. As can be seen in the images above, the 1DX Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G3X was launched at a lower price than the 1DX Mark II, despite having a lens build in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 1D X Mark II vs Canon G3 X

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D X Mark II features a full frame sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1D X Mark II and Canon G3 X sensor measures

Even though the 1DX Mark II has a larger sensor, both cameras offer the same resolution of 20 megapixel. This implies that the 1DX Mark II has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the G3X), which gives it a potential advantage in terms of light gathering capacity. In addition, the 1DX Mark II is a somewhat more recent model (by 7 months) than the G3X, and its sensor might have benefitted from technological advances during this time.

1DX Mark II versus G3X MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 1DX Mark II provides substantially higher image quality than the G3X, with an overall score that is 25 points higher. This advantage is based on 2.7 bits higher color depth, 1.2 EV in additional dynamic range, and 2.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1DX Mark II provides a higher video resolution than the G3X. It can shoot video footage at 4K/60p, while the G3X is limited to 1080/60p.

 

Feature comparison: Canon 1D X Mark II vs Canon G3 X

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1DX Mark II has an optical viewfinder, which can be very useful 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 1D X Mark II, the Canon G3 X, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark II is the clear winner of the match-up (15 : 10 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 when reflecting and deciding on a new camera.

1DX Mark II 15:10 G3X

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 1DX Mark II and the G3X 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
