Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X Mark II and the Canon EOS Rebel XSi? 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.
The physical size and weight of the Canon G1 X Mark II and the Canon XSi 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 width, height and depth measures 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 XSi is considerably larger (47 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the XSi are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II has a lens built in, whereas the XSi 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 XSi and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

|Note: Measurements and pricing do not include easily detachable parts, such as 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. 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.
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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Canon XSi an APS-C sensor. The sensor area in the XSi is 26 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 Mark II has a native 4:3 aspect ratio, while the one in the XSi offers a 3:2 aspect.
In terms of chip-set technology, the G1X Mark II uses a more advanced image processing engine (DIGIC 6) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the Canon G1 X Mark II offers a higher resolution of 13 megapixels, compared with 12.2 MP of the Canon XSi. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.49μm versus 5.19μm for the XSi). However, it should be noted that the G1X Mark II is much more recent (by 6 years) than the XSi, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G1X Mark II indeed provides movie recording capabilities, while the XSi does not. The highest resolution format that the G1X Mark II can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the XSi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. That said, the G1X Mark II 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 G1 X Mark II, the Canon XSi, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark II has a touchscreen, while the XSi has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark II 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 XSi does not have a selfie-screen.
The Canon G1 X Mark II 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 Mark II writes its imaging data to SDXC cards, while the XSi uses SDHC cards. The G1X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the XSi 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 Mark II and Canon EOS Rebel XSi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark II offers wifi support, while the XSi does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The G1X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the XSi has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the XSi was succeeded by the Canon T1i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Is the Canon G1 X Mark II better than the Canon XSi or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G1 X Mark II:
- Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 3).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5.2 vs 3.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with a built-in lens, while the XSi requires a separate lens.
- More compact: Is smaller (116x74mm vs 129x98mm) and thus needs less room in the bag.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 6 years of technical progress since the XSi launch.
Reasons to prefer the Canon EOS Rebel XSi:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (500 versus 240) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in January 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark II is the clear winner of the match-up (15 : 4 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 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 Mark II and the Canon XSi 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 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 Mark II or the XSi perform in practice. 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 expert reviews 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.

The review scores listed above should be treated 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. 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.
