Canon EOS Rebel T3I Feature and Specification

Canon EOS Rebel T3i Features

Canon EOS Rebel T3i has an 18.0 mega pixel CMOS sensor which captures extremely high quality images.This first class sensor is able top capture high resolution pictures enough for enlargement or crops. This first class sensor is same as used in very expensive professional cameras. EOS Rebel T3i uses DIGIC 4 image processor which dramatically speeds the entire EOS Rebel T3i camera's operation for the best performance and offers improvements on image quality details and natural color reproduction. This sensor is capable of achieving phenomenal levels of performance in any situation. The EOS Rebel T3i features an expanded ISO range that makes shooting possible in situations previously unthinkable without flash.

Canon EOS Rebel T3I Review Based on World Wide Customers

The Canon Rebel T3i takes the consumer level dSLR a couple steps closer to the mid-level Canon 60D with the addition of the rotating rear LCD screen, remote flash firing, and in-camera processing features. The already highly competent, older Rebel T2i already shared many important features with the 60D (and even features of the semi-pro 7D) including the 18 MP sensor, 63-zone exposure metering system, high ISO performance, HD movie capabilities, and Digic 4 image processor. With these new upgrades, it might make it even more difficult to choose between them. But there are some important differences.

If you are considering the Rebel T3i vs T2i, the Rebel T3i is replacing the T2i. Since both cameras share the same 18 megapixel sensor and Digic 4 processor, both the T2i and T3i will create images with exactly the same image quality, produce the same low light/ high ISO performance, shoot at 3.7 frames per second, and have nearly the same size and build quality. They are both offered with the same 18-55mm kit lens (with some minor cosmetic differences on the new T3i kit lens). The T3i is very slightly larger and heavier due to the addition of the rotating rear LCD monitor. And that is one of the biggest differences between the two cameras. Do you want and need a vari-angle rear screen or not? The other major difference is the ability of the T3i to remotely control multiple off-camera flashes. Like the 60D and 7D, you can use the built-in flash of the T3i to trigger other Canon Speedlites. Some other minor additions to the T3i include the Scene Intelligent Auto Mode, which is a feature borrowed from point and shoot cameras. When in Auto mode, the T3i will make a determination of what type of scene you are shooting - close-up, portrait, landscape, etc. - and automatically configure the camera settings accordingly. However, if you want to use a powerful and costly digital SLR as a point and shoot, you should probably save the money and just buy a nice, high quality point and shoot like the Canon S95. Other additional but not essential upgrades include the in-camera processing Creative Filters, and the ability to choose different image size ratios and to rate your images. (Helpful hint: press the Q Button while in image playback and you can access features like rating, rotating, and Creative Filters.) There is also a marginally helpful Feature Guide which gives brief descriptions of various settings and some additional video features like Video Snapshot, which you can use to shoot short video clips that are automatically joined together into a video, with music.

Canon Rebel T3i vs. 60D vs. 7D
Sensor and Image Quality: All three cameras share a very similar sensor and 18 megapixels, and so their image quality will be virtually the same. All are capable of taking professional quality images.

Exposure Metering: The three cameras all share the latest 63-zone, dual-layer exposure metering system and 4 metering modes. That means they will all determine the exposure virtually identically and enable you to take properly exposed photos in most every situation, including difficult back-lit scenes. The size of the areas metered for Partial and Spot metering vary slightly between the cameras, but that isn't anything critical.

Autofocus: The T3i shares a similar autofocus system to the 60D, with 9 focus points and three auto focusing modes. However the 9 AF points of the 60D are more sensitive than those of the T3i: all are cross-type in the 60D, only the center is cross-type in the T3i. The 60D autofocus system is much less complex than the sophisticated AF system of the 7D with its 19 AF point system and its additional Zone, Spot, and Expansion focus modes. These various modes address how you want to deal with and group the numerous AF points. Plus the custom settings of the 7D allow one to customize how the AF system works - how it tracks subjects, how it deals with objects that come between you and your initial subject, how quickly it responds to these changes of possible subjects that are at different distances from you, etc. However, if you are not an avid sports photographer, a wildlife shooter, or someone who understands, needs, and will use the elaborate features of the 7D AF system, then this shouldn't sway you.

Construction: As you can probably figure out from the prices, each camera is not built the same. The T3i has relatively strong construction of a stainless steel frame with polycarbonate body. The 60D has a stronger and lighter aluminum frame and polycarbonate body, but not as strong as the 7D's magnesium alloy construction. The 60D also has some amount of weather sealing - more than the T3i, less than the 7D. But for most users, including even those using the camera daily or in travel situations, the construction of any of these cameras is far more than good enough, strong enough, and durable enough.

ISO: Since they all share a very similar sensor, the ISO sensitivity and performance at high ISO settings is virtually the same for these three cameras. But don't take my word for it, don't be swayed by pixel peepers on forums, instead check out the camera sensor tests at dxomark to verify this. As you can see, they all share the exact same overall score, and show very similar performance.

Controls: As with construction, the buttons and controls vary with these cameras. Unlike the T3i, the 60D and 7D have nearly every control an advanced photographer needs on the exterior of the camera and they also have the top LCD panel and rear Quick Control Dial that are not on the T3i. With all the cameras, any controls can also be easily accessed with the Q Button and Q Menu or in the other menus on the rear LCD monitor. The top buttons of the 60D set only one setting each, so this is less complicated than the multiple-setting buttons of the 7D. Canon has removed the white balance (WB) button on the 60D that the 7D has, but that isn't a big deal - use the Q Menu. Another change on the 60D is that the Multi-controller has been moved from the thumb joystick like the 7D and 50D and placed in the middle of the rear Quick-control dial. This doesn't change how it functions, and should just be a matter of getting used to the difference. If you plan on using your camera on Auto or Program most of the time, then the controls of the T3i are more than sufficient for your needs. If you work in Av, Tv, or M modes and need quicker and more direct access to your controls and the additional top LCD screen to view and change your current settings, then you need to consider the 60D or 7D over the T3i.
