Canon G16 vs XSi
The Canon PowerShot G16 and the Canon EOS Rebel XSi (labelled Canon 450D in some countries) are two digital cameras that were announced, respectively, in August 2013 and January 2008. The G16 is a fixed lens compact, while the XSi is a DSLR. The cameras are based on a 1/1.7-inch (G16) and an APS-C (XSi) sensor. The G16 has a resolution of 12 megapixels, whereas the XSi provides 12.2 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 G16 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 side-by-side display below illustrates the physical size and weight of the Canon G16 and the Canon XSi. 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 XSi is considerably larger (53 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the XSi are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G16 was launched at a lower price than the XSi, 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. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 G16 features a 1/1.7-inch sensor and the Canon XSi an APS-C sensor. The sensor area in the XSi is 683 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.6. The sensor in the G16 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 G16 uses a more advanced image processing engine (DIGIC 6) than the XSi (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
With 12.2MP, the XSi offers a higher resolution than the G16 (12MP), but the XSi nevertheless has larger individual pixels (pixel pitch of 5.19μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 5 years and 6 months) than the XSi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel XSi are ISO 100 to ISO 1600 (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 XSi has a markedly higher DXO score than the G16 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.9 EV of lower dynamic range, and 1.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
Many modern cameras cannot only take still pictures, but also record videos. The G16 indeed provides movie recording capabilities, while the XSi does not. The highest resolution format that the G16 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The G16 and the XSi 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 following table reports on some other key feature differences and similarities of the Canon G16, the Canon XSi, and comparable cameras.

|Canon G1 X||optical||n||3.0||922||Swivel||n||1/4000s||1.9||Y||Y|
The Canon G16 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 G16 writes its imaging data to SDXC cards, while the XSi uses SDHC cards. The G16 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 G16 and Canon EOS Rebel XSi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Canon G1 X||Y||stereo||mono||-||-||mini||2.0||-||-||-|
It is notable that the G16 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 G16 is a recent model that features in the current product line-up of Canon. In contrast, the XSi has been discontinued (but 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 how do things add up? Is the Canon G16 better than the Canon XSi or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G16:
- More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
- 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 1080/60p movies.
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- 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 (109x76mm vs 129x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the XSi).
- 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.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 5 years and 6 months of technical progress since the XSi launch.
Arguments in favor of the Canon EOS Rebel XSi:
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
- Faster burst: Shoots at higher frequency (3.5 vs 2.2 flaps/sec) to capture the decisive moment.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (500 versus 360) 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 G16 is the clear winner of the match-up (13 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G16 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 where reviews by experts come in. 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
