Canon G16 vs T4i
The Canon PowerShot G16 and the Canon EOS Rebel T4i (labelled Canon 650D in some countries) are two digital cameras that were officially introduced, respectively, in August 2013 and June 2012. The G16 is a fixed lens compact, while the T4i is a DSLR. The cameras are based on a 1/1.7-inch (G16) and an APS-C (T4i) sensor. The G16 has a resolution of 12 megapixels, whereas the T4i provides 17.9 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 T4i? 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 G16 and the Canon T4i 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 Canon T4i is considerably larger (61 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the T4i 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 T4i 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 T4i 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. 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 obviously take relative prices into account. 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 T4i, 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G16 features a 1/1.7-inch sensor and the Canon T4i an APS-C sensor. The sensor area in the T4i is 690 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 T4i offers a 3:2 aspect.
In terms of chip-set technology, the G16 uses a more advanced image processing engine (DIGIC 6) than the T4i (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
With 17.9MP, the T4i offers a higher resolution than the G16 (12MP), but the T4i nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a somewhat more recent model (by 1 year and 2 months) than the T4i, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon G16 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel T4i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
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"). Of the two cameras under consideration, the T4i has a markedly higher DXO score than the G16 (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.5 EV of lower dynamic range, and 1.7 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.
|4.||Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|8.||Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G16 provides a higher frame rate than the T4i. It can shoot video footage at 1080/60p, while the T4i is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The G16 and the T4i 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 G16 and Canon T4i 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 T4i has a touchscreen, while the G16 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T4i has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the G16 does not have a selfie-screen.
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.
Concerning the storage of imaging data, both the G16 and the T4i write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 T4i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 offers wifi support, while the T4i 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 T4i has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the T4i was succeeded by the Canon T5i. 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 G16 better than the Canon T4i or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G16:
- Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 5).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with a built-in lens, while the T4i requires a separate lens.
- More compact: Is smaller (109x76mm vs 133x100mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the T4i).
- 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.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Is somewhat more recent (announced 1 year and 2 months after the T4i).
Advantages of the Canon EOS Rebel T4i:
- More detail: Has more megapixels (17.9 vs 12MP), which boosts linear resolution by 25%.
- Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (1.7 stops ISO advantage).
- 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).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (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 (440 versus 360) out of a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in June 2012).
If the number of relative strengths (bullet points above) is taken as a guide, the T4i emerges as the winner of the match-up (13 : 10 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 G16 and the Canon T4i 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G16 or the T4i. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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], 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
