Canon T4i vs 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 revealed to the public, 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 megapixels, whereas the T6i provides 24 MP.
As their names suggest, both the Canon EOS Rebel T4i and the Canon EOS Rebel T6i belong to Canon's Rebel line of DSLR cameras. This range of APS-C cameras, which started out with the Canon EOS Digital Rebel in 2003, has been a big commercial success and the backbone of Canon's dominance in the digital camera market. The popularity of the Rebel cameras is the result of them inheriting much of the sensor and shooting technology from earlier released professional DSLRs, while being sold at a much more budget-friendly price point. The strong brand reputation of Canon and the comprehensive EOS system of compatible lenses and accessories further contributes to the appeal of the Rebel cams, including the Canon T4i and Canon T6i. 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 EOS Rebel T4i and the Canon EOS Rebel T6i? 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.
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.
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 T6i are 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 compare the optics available in the Canon EF Lens Catalog.

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. 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.
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. 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.
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, the T6i uses a more advanced image processing engine (DIGIC 6) than the T4i (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the T6i offers a higher resolution of 24 megapixels, compared with 17.9 MP of the T4i. This megapixels 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.
The resolution advantage of the Canon T6i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon T4i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS Rebel T4i has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The Canon EOS Rebel T6i offers exactly the same ISO settings.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
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, and both provide the same movie specifications (1080/30p).
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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the T4i has a higher magnification than the one of the T6i (0.53x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. 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.
Concerning the storage of imaging data, both the T4i and the T6i write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 EOS Rebel T4i and Canon EOS Rebel T6i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6i offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the T4i does not provide wifi capability.
Both the T4i and the T6i have been discontinued, but can regularly be found used on eBay. The T4i was replaced by the Canon T5i, while the T6i was followed by the Canon T7i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon T4i and the Canon T6i? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS Rebel T4i:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.51x).
- More heavily discounted: Has been available for much longer (launched in June 2012).
Advantages 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 jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 5).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- 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 relative strengths (bullet points above) is taken as a measure, the T6i is the clear winner of the contest (9 : 2 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 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the T4i or the T6i perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
