Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G3 X and the Pentax K-1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison: Canon G3 X vs Pentax K-1
An illustration of the physical size and weight of the Canon G3 X and the Pentax K-1 is provided 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 width, height and depth dimensions are rounded to the nearest millimeter.
The K-1 can be obtained in two different colors (black, silver), while the G3X is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 is considerably larger (59 percent) than the Canon G3 X. 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 built in, whereas the K-1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 K-1, despite having a lens built 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.
Sensor comparison: Canon G3 X vs Pentax K-1
The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 is 643 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 36.2MP, the K-1 offers a higher resolution than the G3X (20MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 2.41μm for the G3X) due to its larger sensor. Moreover, the K-1 is a somewhat more recent model (by 8 months) than the G3X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inch or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inch or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inch or 62.3 x 41.6 cm. The corresponding values for the Canon G3 X are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 cm for excellent quality prints.
Unlike the G3X, the K-1 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon PowerShot G3 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).
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 consideration, the K-1 offers substantially better image quality than the G3X (overall score 33 points higher). The advantage is based on 4 bits higher color depth, 2.3 EV in additional dynamic range, and 2.7 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 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 G3X provides a higher frame rate than the K-1. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/60i.
Feature comparison: Canon G3 X vs Pentax K-1
Apart from body and sensor, cameras can and do differ across a range of features. For example, the K-1 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 G3 X, the Pentax K-1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The G3X has one, while the K-1 does not. While the built-in flash of the G3X is not very powerful, it can at times be useful as a fill-in light.The G3X has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the K-1 does not have a selfie-screen.
The Pentax K-1 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the G3X and the K-1 write their files to SDXC cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G3X only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
Connectivity comparison: Canon G3 X vs Pentax K-1
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G3 X and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Pentax K-1 (unlike the G3X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G3X is a recent model that features in the current product line-up of Canon. In contrast, the K-1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the K-1 was succeeded by the Pentax K-1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 is the clear winner of the contest (17 : 13 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G3 X and the Pentax K-1 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G3X and the K-1 in practical situations. 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.
Expert reviews: Canon G3 X vs Pentax K-1
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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.
