The Canon EOS 70D DSLR Camera features a 20.2 megapixel APS-C CMOS sensor and DIGIC 5+ image processor to ensure high-resolution images and excellent low-light sensitivity. Both the sensor and processor work together to produce well-detailed, clear imagery that exhibits natural tonality and color gradations with minimal noise when working in difficult lighting conditions. The processor also provides notable speed throughout the camera system, including the ability to record up to 7 fps in full-resolution, quickened AF speeds, and full HD 1080p video recording in multiple frame rates with manual exposure and audio level control.
Serving to both still and movie shooting modes, Dual Pixel CMOS AF is a powerful technology that revolves around the incorporation of two photodiodes within each pixel to provide an expansive phase-detection focusing system. This system affords focusing advantages that are similar to how a camcorder works and as such can focus on subjects in an incredibly fast and precise manner. The benefits of this system are three-fold: the ability to focus quickly and smoothly; the ability to truly utilize the vari-angle touchscreen LCD monitor to its full potential; and the ability to utilize a wide range of over 100 EF and EF-S lenses. Also benefiting from Dual Pixel CMOS AF is the Movie Servo AF mode, which enables continuous auto focusing when recording movies.
The 3.0″ 1,040k-dot vari-angle Clear View II touchscreen LCD monitor profits greatly from the advent of the Dual Pixel CMOS AF system and its ability to utilize Touch AF focusing for finely controlled selection of the point of focus. The monitor’s vari-angle design also enables more efficient shooting and viewing from both high and low angles and an anti-reflective, smudge-resistant coating allows for clear well-detailed viewing. In addition to the LCD monitor, the 70D also features an optical pentaprism finder that can be used for eye-level shooting of still images. This Intelligent Viewfinder incorporates a superimposed LCD to provide an intuitive means for monitoring exposure and camera settings during shooting.
While working with the viewfinder, an expansive 19-point all cross-type AF system is visualized for acquiring focus; integral to this array is a high-precision dual-cross center AF point that is compatible with f/2.8 and faster lenses.
Providing a wealth of additional functionality to the camera is integrated Wi-Fi connectivity, which allows instant and direct sharing of image files to an iOS or Android mobile device for sharing online. This functionality also allows for wireless remote control over camera settings, including exposure controls, focusing, and shutter release, from a mobile device when using the Canon EOS Remote app.
Dual Pixel CMOS AF
Dual Pixel CMOS AF is a refined live view focusing technology that works to provide incredibly quick and precise auto focusing abilities that function 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 to help reduce focus hunting for faster, more direct control of focus placement.
Dual Pixel CMOS AF is utilized during live view applications, for either still or video shooting, and enables an enhanced method of working with the vari-angle touchscreen LCD monitor.
The focusing system provides full and intuitive use of the vari-angle touchscreen monitor through its keen integration of touch controls for focusing and articulating design of the screen for viewing from any shooting angle.
CMOS Sensor and DIGIC 5+ Image Processor
In regard to imaging capabilities, the EOS 70D features a 20 megapixel APS-C CMOS sensor and DIGIC 5+ image processor to produce high-resolution, well-detailed still imagery and full HD 1080p video with notable low-light sensitivity. These two technologies work together to enable 14-bit A/D conversion, which helps to improve the quality and gradation of imagery by producing smoother, more natural-looking results with minimal image noise.
A native ISO sensitivity of 100-12800 is well-suited to working in difficult lighting conditions and the processing power of the DIGIC 5+ processor also affords a wealth of speed to all aspects of the camera, including a full-resolution continuous shooting rate of 7 fps.
EOS HD Video
Full HD 1080p video recording is supported at 30, 24, and 25 fps as well as HD and SD video recording in multiple frame rates. Video is recorded using the high-quality H.264/MPEG-4 AVC codec and manual exposure control is supported for greater refinement over the look and feel of recordings. Video clips are automatically partitioned after the file size has reached 4GB and both IPB and All i-frame compression are available for use depending on editing and output preferences.
Sound can be recorded using the built-in stereo microphone, or with an optional external microphone using the 3.5mm microphone terminal, and controlled manually across 64 levels. An attenuator function is also employed to prevent audio clipping for cleaner overall sound.
The Video Snapshot mode can also be used to record short video clips, in 2, 4, or 8-second segments, and in-camera editing and music can be applied to these files for finalized results straight from the camera.
3.0″ Clear View LCD Monitor
A large, bright 3.0″ 1,040k-dot vari-angle Clear View II touchscreen LCD monitor is integrated into the 70D to enable clear live view monitoring, image playback, and intuitive menu navigation. It’s vari-angle design aids in viewing from high and low angles and the touchscreen control gives way to efficient navigation of menus and shooting controls, as well as precise control over focus points. The screen’s construction incorporates an anti-reflective, smudge-resistant coating to provide clearer viewing, even in bright, sunlit conditions.
When working with still imagery and shooting at eye-level, an optical pentaprism Intelligent Viewfinder is available and provides 98% frame coverage. A superimposed LCD screen within the viewfinder provides pertinent exposure and camera information for more efficient eye-level shooting and also has the ability to outline AF points, grid lines, and an electronic level to aid in composition.
