The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon T4i was launched in the US market at a price of $849. 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 with a 35mm slide
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.
The Canon T4i features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the Canon T4i among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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. 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 cannot only take still pictures, but also record videos. The T4i indeed provides movie recording capabilities. The highest resolution format that the T4i can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the T4i has an optical viewfinder that provides a field of view of 95% and a magnification of 0.53x. The following tables report on some other key feature differences and similarities of the Canon T4i and comparable cameras.

One convenient feature of the T4i is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
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, 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. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
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 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).
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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
Canon T4i FAQ
Below are some additional questions and answers concerning some particular features of the T4i.
What technology is the imaging sensor in the T4i based on?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Canon equipped the T4i with the DIGIC 5 image processor.
What is the ISO sensitivity range of the T4i?
The camera has a native sensitivity range from ISO 100 to ISO 12800.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the T4i is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the Canon EOS Rebel T4i?
Canon mentions a shutter rating of 100 000 actuations for the T4i. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the T4i over, say, three years, one would have to take about 100 pictures each and every day.
Does the Canon T4i feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The T4i's flash sync speed is 1/200 sec.
Does the Canon T4i support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).
Which battery does the T4i use?
The camera gets its power from the LP-E8 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the T4i?
