Canon T6i versus Canon 70D

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Canon EOS 70D are two digital cameras that were officially introduced, respectively, in February 2015 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The T6i has a resolution of 24 megapixel, whereas the 70D provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon T6i vs Canon 70D

The physical size and weight of the Canon T6i and the Canon 70D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the T6i – represents 100 percent 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 70D is notably larger (8 percent) than the Canon T6i. Moreover, the 70D is substantially heavier (36 percent) than the T6i. It is noteworthy in this context that the 70D is splash and dust-proof, while the T6i does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the T6i gets 440 shots out of its LP-E17 battery, while the 70D can take 920 images on a single charge of its LP-E6 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.

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 T6i was launched at a markedly lower price (by 38 percent) than the 70D, which puts it into a different market segment. 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: Canon T6i vs Canon 70D

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 70D is 2 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T6i and Canon 70D sensor measures

Despite having a slightly smaller sensor, the Canon T6i offers a higher resolution of 24 megapixel, compared with 20 MP of the Canon 70D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.11μm for the 70D). However, it should be noted that the T6i is a somewhat more recent model (by 1 year and 7 months) than the 70D, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

T6i versus 70D MP

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 T6i provides a higher frame rate than the 70D. It can shoot video footage at 1080/60p, while the 70D is limited to 1080/30p.

 

Feature comparison: Canon T6i vs Canon 70D

Beyond body and sensor, cameras can and do differ across a range of features. The T6i and the 70D 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 table below summarizes some of the other core capabilities of the Canon T6i and Canon 70D in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the T6i and the 70D have been discontinued, but can regularly be found used on eBay. The 70D was replaced by the Canon 80D, while the T6i was followed by the Canon T7i.

Review summary: Canon T6i vs Canon 70D

So what is the bottom line? Is there a clear favorite between the Canon T6i and the Canon 70D? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS Rebel T6i:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Less heavy: Is lighter (by 200g or 26 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 7 months after the 70D).


Reasons to prefer the Canon EOS 70D:

  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (920 versus 440) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been on the market for longer (launched in July 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the 70D comes out slightly ahead of the T6i (6 : 5 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.

T6i 05:06 70D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the T6i or the 70D. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important.

The review scores listed above should be treated 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
