Canon T3 vs T4i
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Canon EOS Rebel T4i (labelled Canon 650D in some countries) are two digital cameras that were officially introduced, respectively, in February 2011 and June 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The T3 has a resolution of 12.2 megapixels, whereas the T4i provides 17.9 MP.
As their names suggest, both the Canon EOS Rebel T3 and the Canon EOS Rebel T4i 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 T3 and Canon T4i. 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 T3 and the Canon EOS Rebel T4i? 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 T3 and the Canon T4i 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T4i is somewhat larger (2 percent) than the Canon T3. Moreover, the T4i is markedly heavier (16 percent) than the T3. In this context, it is worth noting that neither the T3 nor the T4i 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.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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. The T3 was launched at a markedly lower price (by 47 percent) than the T4i, 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.
The size of the imaging sensor is a crucial determinant 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the T4i is 3 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.
Technology-wise, the T4i uses a more advanced image processing engine (DIGIC 5) than the T3 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 17.9MP, the T4i offers a higher resolution than the T3 (12.2MP), but the T4i has smaller individual pixels (pixel pitch of 4.31μm versus 5.15μm for the T3). Yet, the T4i is a somewhat more recent model (by 1 year and 4 months) than the T3, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon T3 are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.
The T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T3 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Canon EOS Rebel T4i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 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 T4i provides a better video resolution than the T3. It can shoot movie footage at 1080/30p, while the T3 is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The T3 and the T4i 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 T3 (0.53x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T3, the Canon T4i, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T4i has a touchscreen, while the T3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T4i has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the T3 does not have a selfie-screen.
Concerning the storage of imaging data, both the T3 and the T4i write their files to SDXC cards. The T4i 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.
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 T3 and Canon EOS Rebel T4i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T4i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The T3 does not feature such a mic input.
Both the T3 and the T4i have been discontinued, but can regularly be found used on eBay. The T3 was replaced by the Canon T5, while the T4i was followed by the Canon T5i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the count of individual advantages (bullet points above) is taken as a guide, the T4i is the clear winner of the contest (14 : 4 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. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the T3 and the T4i 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.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 above review scores should be interpreted 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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
