Canon T6s vs G3X

The Canon EOS Rebel T6s (called Canon 760D in some regions) and the Canon PowerShot G3 X are two digital cameras that were revealed to the public, respectively, in February 2015 and June 2015. The T6s is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (T6s) and an one-inch (G3X) sensor. The T6s has a resolution of 24 megapixels, whereas the G3X provides 20 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon T6s vs G3X

An illustration of the physical size and weight of the Canon T6s and the Canon G3 X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the T6s – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G3 X is notably smaller (29 percent) than the Canon T6s. It is noteworthy in this context that the G3X is splash and dust-proof, while the T6s does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the T6s 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 T6s and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the T6s gets 440 shots out of its LP-E17 battery, while the G3X can take 300 images on a single charge of its NB-10L 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.

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. 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.

 

Sensor comparison: Canon T6s vs G3X

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T6s features an APS-C sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T6s and Canon G3 X sensor measures

With 24MP, the T6s offers a higher resolution than the G3X (20MP), but the T6s nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G3X) due to its larger sensor. However, the G3X is a somewhat more recent model (by 4 months) than the T6s, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The T6s has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS Rebel T6s has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot G3 X are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600..

T6s versus G3X MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the T6s has a notably higher overall DXO score than the G3X (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 0.3 EV of lower dynamic range, and 0.8 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 G3X provides a faster frame rate than the T6s. It can shoot movie footage at 1080/60p, while the T6s is limited to 1080/30p.

 

Feature comparison: Canon T6s vs G3X

Beyond body and sensor, cameras can and do differ across a range of features. For example, the T6s has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon T6s and Canon G3 X along with similar information for a selection of comparators.

One feature that is present on the T6s, but is missing on the G3X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

Concerning the storage of imaging data, both the T6s and the G3X write their files to SDXC cards.

Connectivity comparison: Canon T6s vs G3X

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 G3X is a recent model that features in the current product line-up of Canon. In contrast, the T6s has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the T6s was succeeded by the Canon 77D.


Review summary: Canon T6s vs G3X

So how do things add up? Which of the two cameras – the Canon T6s or the Canon G3 X – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS Rebel T6s:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (440 versus 300) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).


Arguments in favor of the Canon PowerShot G3 X:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the T6s requires a separate lens.
  • More compact: Is smaller (123x77mm vs 132x101mm) and will fit more readily into a bag.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the T6s emerges as the winner of the contest (12 : 10 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.

T6s 12:10 G3X

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the T6s and the G3X in practical situations. 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.

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.
