Canon G16 vs T3

The Canon PowerShot G16 and the Canon EOS Rebel T3 (labelled Canon 1100D in some countries) are two digital cameras that were announced, respectively, in August 2013 and February 2011. The G16 is a fixed lens compact, while the T3 is a DSLR. The cameras are based on a 1/1.7-inch (G16) and an APS-C (T3) sensor. The G16 has a resolution of 12 megapixels, whereas the T3 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 T3? 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 physical size and weight of the Canon G16 and the Canon T3 are illustrated 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 measures are rounded to the nearest millimeter.

Compare G16 versus T3 top
Comparison G16 or T3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T3 is considerably larger (57 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the T3 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 T3 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 T3 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the G16 gets 360 shots out of its NB-10L battery, while the T3 can take 700 images on a single charge of its LP-E10 power pack.

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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 T3 an APS-C sensor. The sensor area in the T3 is 669 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 T3 offers a 3:2 aspect.

In terms of chip-set technology, the G16 uses a more advanced image processing engine (DIGIC 6) than the T3 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

Canon G16 and Canon T3 sensor measures

With 12.2MP, the T3 offers a higher resolution than the G16 (12MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 2 years and 6 months) than the T3, 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 T3 are ISO 100 to ISO 6400 (no boost).

G16 versus T3 MP

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"). Of the two cameras under consideration, the T3 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 0.9 bits higher color depth, 0.7 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.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G16 provides a higher video resolution than the T3. It can shoot video footage at 1080/60p, while the T3 is limited to 720/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G16 and the T3 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 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 T3 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 T3 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 T3 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 T3 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 T3 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the T3 was succeeded by the Canon T5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary

So what is the bottom line? Which of the two cameras – the Canon G16 or the Canon T3 – has the upper hand? Is one clearly better than the other? 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 (0.7 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4).
  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • 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 T3 requires a separate lens.
  • More compact: Is smaller (109x76mm vs 130x100mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the T3).
  • 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 modern: Reflects 2 years and 6 months of technical progress since the T3 launch.


Advantages of the Canon EOS Rebel T3:

  • 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).
  • 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 (700 versus 360) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in February 2011).

If the count of relative strengths (bullet points above) is taken as a measure, the G16 is the clear winner of the match-up (13 : 6 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.

G16 13:06 T3

How about other alternatives? Do the specifications of the Canon G16 and the Canon T3 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G16 or the T3 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.

Expert reviews

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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
