Packing a versatile feature-set in a sleek and portable body, the EOS Rebel T7i DSLR from Canon offers advanced imaging capabilities along with a convenient range of controls and connectivity. Utilizing a 24.2MP APS-C CMOS sensor and DIGIC 7 image processor, the Rebel T7i is able to capture high-resolution stills and video with an expanded sensitivity range of ISO 100-51200 to suit working in a wide variety of lighting conditions. The sensor and processor combination also avails 6 fps continuous shooting for working with moving subjects. Benefitting the imaging attributes, the sensor’s design also facilitates Dual Pixel CMOS AF, which uses phase-detection autofocus for quick, accurate, and smooth focusing performance when recording movies or shooting stills in live view. When shooting stills using the optical viewfinder, a 45-point all cross-type phase-detection system is used for quick and accurate focusing in a variety of shooting scenarios.
In regard to the physical design, a large 3.0″ 1.04m-dot touchscreen LCD is featured for intuitive settings control and live view monitoring, and it uses a vari-angle design to permit easier viewing from high and low working angles. Additionally, built-in Wi-Fi with NFC is available for quick and convenient pairing with a smartphone or tablet for wireless image sharing, and Bluetooth is also featured for image sharing to and remote camera control from a mobile device.
24.2MP APS-C CMOS Sensor and DIGIC 7 Image Processor
Both a 24.2MP APS-C CMOS sensor and DIGIC 7 image processor are used to deliver high sensitivity and fast camera performance to suit both stills and video applications. A flexible native ISO 100-25600 range, which can be extended to ISO 51200, suits working in a variety of lighting conditions, and the processing capabilities minimize noise for notable clarity. The processor also contributes to a fast 6 fps continuous shooting rate for photographing fast-moving subjects.
45-Point All Cross-Type AF and Dual Pixel CMOS AF Systems
Benefitting stills shooting with the optical viewfinder, a wide-area 45-point all cross-type phase-detection autofocus system provides quick and precise focusing in difficult lighting conditions. The cross-type design of the sensors affords greater accuracy in low-contrast and mixed lighting conditions, and the broad coverage of the 45 sensors is ideal for tracking and maintaining focus on moving subjects.
When recording video or shooting in live view, a Dual Pixel CMOS AF system is employed that offers smooth and fast focusing performance in a similar manner to how a camcorder acquires focus. This system integrates two separate photodiodes within each pixel to provide a broad and dense network of phase-detection gathering elements across a majority of the image sensor to reduce focus hunting for faster, more direct control of focus placement. When working with still imagery, this focusing system works to acquire focus quickly and accurately, making it ideally suited to shooting and tracking moving subjects so that critical focus is attained with each shot. When shooting video, a Movie Servo AF mode offers smooth and natural focusing when changing from different subjects or different distances within the scene, as well as the ability to specify tracking sensitivity, AF speed, and Face Tracking priority. Benefited by the Touch AF system, rack focus is possible simply by touching elements within the scene on the touchscreen in order to change focus in an intuitive manner. Subject tracking in movies is also heightened due to the Dual Pixel CMOS AF system’s ability to recognize subjects and maintain focus when working within changing or cluttered scenery.
Full HD 1080p Video Recording
In addition to stills recording, the T7i also supports Full HD 1080p video recording at up to 60 fps in the MP4 format with IPB compression, or 30 fps in the MOV format with ALL-I compression when making in-camera time-lapse movies. Video recording is benefitted by the inclusion of Dual Pixel CMOS AF and the Movie Servo AF focusing functions, as well as the touchscreen design of the LCD monitor for intuitive control. Movie Electronic IS is also featured to minimize the appearance of camera shake across five axes for smoother, steadier recording when shooting handheld. Additionally, an external microphone jack is incorporated in the body design for greater control over your recorded sound.
Unique to most video recording systems, the T7i also features an HDR Movie mode that can be used to achieve greater highlight and shadow detail when recording in high contrast scenarios. This mode captures two HD frames at different exposures, one normal and one underexposed, in short succession at up to 60 fps and then composites them during playback at 30 fps to create a movie with a longer-appearing dynamic range.
