Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G16 and the Canon EOS Rebel T100? 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

An illustration of the physical size and weight of the Canon G16 and the Canon T100 is provided 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 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 T100 is considerably larger (59 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the T100 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 T100 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 T100 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the G16 gets 360 shots out of its Canon NB-10L battery, while the T100 can take 500 images on a single charge of its Canon LP-E10 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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 T100 an APS-C sensor. The sensor area in the T100 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 T100 offers a 3:2 aspect.

In terms of chip-set technology, the G16 uses a more advanced image processing engine (DIGIC 6) than the T100 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

With 17.9MP, the T100 offers a higher resolution than the G16 (12MP), but the T100 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.87μm for the G16) due to its larger sensor. Moreover, the T100 is a much more recent model (by 4 years and 6 months) than the G16, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon T100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T100 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 Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel T100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the G16 is build around a BSI-CMOS sensor, while the T100 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the T100 has a markedly higher DXO score than the G16 (overall score 9 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.3 EV of lower dynamic range, and 1.6 stops in additional low light sensitivity. 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 G16 provides a higher frame rate than the T100. It can shoot video footage at 1080/60p, while the T100 is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G16 and the T100 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 T100 along with similar information for a selection of comparators.

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 T100 write their files to SDXC cards. The G16 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T100 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 G16 and Canon EOS Rebel T100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The T100 is a recent model that features in the current product line-up of Canon. In contrast, the G16 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the G16 from Canon. Further information on the features and operation of the G16 and T100 can be found, respectively, in the Canon G16 Manual (free pdf) or the online Canon T100 Manual.

Review summary

So what conclusions can be drawn? Is the Canon G16 better than the Canon T100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot G16:

• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4+).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• 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 T100 requires a separate lens.
• More compact: Is smaller (109x76mm vs 129x102mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the T100).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been available for much longer (launched in August 2013).

Arguments in favor of the Canon EOS Rebel T100:

• More detail: Has more megapixels (17.9 vs 12MP), which boosts linear resolution by 25%.
• Better image quality: Scores markedly higher (9 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 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.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Reflects 4 years and 6 months of technical progress since the G16 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G16 emerges as the winner of the contest (11 : 8 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 G16 and the Canon T100 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 says little about, for example, the shooting experience and imaging performance of the G16 and the T100 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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.

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

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
