Canon G1 X vs Sony A1
The Canon PowerShot G1 X and the Sony A1 are two digital cameras that were revealed to the public, respectively, in January 2012 and January 2021. The G1X is a fixed lens compact, while the A1 is a mirrorless interchangeable lens camera. The cameras are based on an 1.5-inch (G1X) and a full frame (A1) sensor. The Canon has a resolution of 14.2 megapixels, whereas the Sony provides 49.8 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X and the Sony A1? 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.
An illustration of the physical size and weight of the Canon G1 X and the Sony A1 is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A1 is notably larger (32 percent) than the Canon G1 X. It is noteworthy in this context that the A1 is splash and dust-proof, while the G1X does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the A1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A1 and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the G1X gets 250 shots out of its NB-10L battery, while the A1 can take 530 images on a single charge of its NP-FZ100 power pack. The power pack in the A1 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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 G1X was launched at a lower price than the A1, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant 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. 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 features an 1.5-inch sensor and the Sony A1 a full frame sensor. The sensor area in the A1 is 229 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 1.0. The sensor in the G1X has a native 4:3 aspect ratio, while the one in the A1 offers a 3:2 aspect.
With 49.8MP, the A1 offers a higher resolution than the G1X (14.2MP), but the A1 has smaller individual pixels (pixel pitch of 4.16μm versus 4.30μm for the G1X). Yet, the A1 is a much more recent model (by 9 years) than the G1X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A1 for good quality output (200 dots per inch) amounts to 43.2 x 28.8 inches or 109.7 x 73.2 cm, for very good quality (250 dpi) 34.6 x 23 inches or 87.8 x 58.5 cm, and for excellent quality (300 dpi) 28.8 x 19.2 inches or 73.2 x 48.8 cm. The corresponding values for the Canon G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.
The A1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the G1X, the A1 has the capacity to capture high quality composite images (YESMP) 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 G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sony A1 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 500-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A1 provides a better video resolution than the G1X. It can shoot movie footage at 8k/30p, while the Canon is limited to 1080/24p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A1 has an electronic viewfinder (9437k dots), while the G1X has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Canon G1 X, the Sony A1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The G1X has one, while the A1 does not. While the built-in flash of the G1X is not very powerful, it can at times be useful as a fill-in light.The G1X 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 A1 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sony A1 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.
The G1X writes its imaging data to SDXC cards, while the A1 uses CFexpress or SDXC cards. The A1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1X only has one slot. The A1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G1X cannot take advantage of Ultra High Speed SD cards.
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 G1 X and Sony A1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1X does not provide wifi capability.
Studio photographers will appreciate that the Sony A1 (unlike the G1X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The A1 is a recent model that features in the current product line-up of Sony. In contrast, the G1X has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G1X was succeeded by the Canon G1X Mark 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 Sony websites.
So how do things add up? Is the Canon G1 X better than the Sony A1 or vice versa? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the A1 is the clear winner of the contest (29 : 9 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. 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 G1 X and the Sony A1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 remains incomplete and does no justice, for example, to the way the G1X or the A1 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 ratings are only valid when referring 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
