Canon T4i versus Canon T6i

The Canon EOS Rebel T4i (called Canon 650D in some regions) and the Canon EOS Rebel T6i (labelled Canon 750D in some countries) are two digital cameras that were officially introduced, respectively, in June 2012 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The T4i has a resolution of 17.9 megapixel, whereas the T6i provides 24 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 T4i vs Canon T6i

The physical size and weight of the Canon T4i and the Canon T6i are illustrated 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 use the toggle button 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 – the T4i – 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 T4i and the Canon T6iare of equal size. However, the T6i is slightly lighter (3 percent) than the T4i. In this context, it is worth noting that neither the T4i nor the T6i are weather-sealed.

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.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, just click on the right or left arrow next to the camera that you would like to inspect. Alternatively, you can also use the CAM-parator to select your camera combination among a larger number of options.

Any camera purchase 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. The T6i was launched at a somewhat lower price (by 12 percent) than the T4i, which makes it more attractive for photographers on a tight budget. 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: Canon T4i vs Canon T6i

The size of the sensor inside a digital camera is one of the key determinants 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. 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.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon T4i and Canon T6i sensor measures

While the two cameras under review share the same sensor size, the T6i offers a higher resolution of 24 megapixel, compared with 17.9 MP of the T4i. This megapixel advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the T6i has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the T4i). However, it should be noted that the T6i is much more recent (by 2 years and 7 months) than the T4i, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

T4i versus T6i 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 T6i has a markedly higher DXO score than the T4i (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.8 EV in additional dynamic range, and 0.3 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the T6i provides a faster frame rate than the T4i. It can shoot movie footage at 1080/60p, while the T4i is limited to 1080/30p.

 

Feature comparison: Canon T4i vs Canon T6i

Beyond body and sensor, cameras can and do differ across a range of features. The T4i and the T6i 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 T4i and Canon T6i along with similar information for a selection of comparators.

Review summary: Canon T4i vs Canon T6i

So how do things add up? Which of the two cameras – the Canon T4i or the Canon T6i – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS Rebel T4i:

  • More heavily discounted: Has been available for much longer (launched in June 2012).


Arguments in favor of the Canon EOS Rebel T6i:

  • More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More affordable: Was released into a lower priced segment (12 percent cheaper at launch).
  • More modern: Reflects 2 years and 7 months of technical progress since the T4i launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T6i is the clear winner of the contest (7 : 1 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.

T4i 01:07 T6i

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the T4i or the T6i handle or perform in practice. 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 where reviews by experts come in.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
