Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X and the Canon EOS Rebel T8i? 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

The side-by-side display below illustrates the physical size and weight of the Canon G1 X and the Canon T8i. 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 Canon T8i is notably larger (42 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the T8i are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the T8i 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 T8i and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the G1X gets 250 shots out of its Canon NB-10L battery, while the T8i can take 800 images on a single charge of its Canon LP-E17 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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

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. 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 G1 X features an 1.5-inch sensor and the Canon T8i an APS-C sensor. The sensor area in the T8i is 27 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 1.6. The sensor in the G1X has a native 4:3 aspect ratio, while the one in the T8i offers a 3:2 aspect.

Technology-wise, the T8i uses a more advanced image processing engine (DIGIC 8) than the G1X (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

With 24MP, the T8i offers a higher resolution than the G1X (14.2MP), but the T8i has smaller individual pixels (pixel pitch of 3.72μm versus 4.30μm for the G1X). Yet, the T8i is a much more recent model (by 8 years and 1 month) 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.

The resolution advantage of the Canon T8i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T8i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 T8i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel T8i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the T8i provides a better video resolution than the G1X. It can shoot movie footage at 4K/24p, while the G1X is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G1X and the T8i are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The adjacent table lists some of the other core features of the Canon G1 X and Canon T8i along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T8i has a touchscreen, while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon T8i 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 G1X and the T8i write their files to SDXC cards. The T8i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1X cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 Canon EOS Rebel T8i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T8i 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.

Both the G1X and the T8i have been discontinued, but can regularly be found used on ebay. The G1X was replaced by the Canon G1X Mark II, while the T8i does not have a direct successor. Further information on the features and operation of the G1X and T8i can be found, respectively, in the Canon G1 X Manual (free pdf) or the online Canon T8i Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon G1 X and the Canon T8i? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot G1 X:

• Ready to shoot: Comes with a built-in lens, while the T8i requires a separate lens.
• More compact: Is smaller (117x81mm vs 131x103mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been available for much longer (launched in January 2012).

Arguments in favor of the Canon EOS Rebel T8i:

• More detail: Has more megapixels (24 vs 14.2MP), which boosts linear resolution by 33%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 5).
• Better video: Provides higher definition movie capture (4K/24p vs 1080/24p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (7.5 vs 1.9 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (800 versus 250) out of a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 8 years and 1 month of technical progress since the G1X launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T8i is the clear winner of the contest (19 : 4 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Canon T8i place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G1X and the T8i 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

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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
