![]() This is known as 'Intelligent Tracking and Recognition', or iTR for short, and it's the first time we're seeing iTR outside of the 1D X. ![]() The RGB + IR metering sensor is also used for subject recognition to aid focus tracking in AI Servo mode. Intelligent Tracking and Recognition (iTR) The extra resolution over the 63-zone sensor pictured at the left offers for more accurate metering, as well subject tracking in conjunction with the AF system. The 7D Mark II has a 150,000-pixel RGB + IR metering sensor, much like the 100,000-pixel metering sensor from the 1D X pictured here. You can see 7x9 grid of sensors that make up the 63 zones. This is the iFCL metering sensor previously found in the 7D,ĥD Mark III, 6D, etc. Frankly, we'd like to see the metering sensor technology and all its benefits (scene analysis, spot-metering linked to AF point, and iTR) in every Canon DSLR - much as Nikon has done across its DSLR line. And while it's exciting to see this technology filter down from the 1D X, we're confused as to why Canon left out the 1D X's ability to link spot-metering to the selected AF point. The ability of the sensor to use color and IR information to 'see' the scene and perform scene analysis should theoretically result in more accurate metering compared to the 63-zone metering system found in the 7D and 5D Mark III. With the 7D Mark II, Canon is also introducing a new RGB + IR metering sensor with 150,000 pixels, filtering in and improving upon the technology introduced in the 1D X. * Brand new 150,000-pixel RGB + IR metering sensor This should aid in shallow depth-of-field applications where faster lenses require critical focus. The dual diagonal sensors have wider baselines, which essentially means they can provide higher focus accuracy. This means it's capable of detecting diagonal lines with wide aperture lenses, in addition to horizontal and vertical lines (it offers x shaped as well as + shaped sensors). To combat challenging focus scenarios, the center AF point in the 7D Mark II is both dual cross-type and high-precision when a f/2.8 or faster lens is attached. Furthermore, it appears that the center horizontally-sensitive (which appear as vertical stripes) and diagonally-sensitive sensors are slightly offset for the detection of 'zig-zag' lines - click on the image for a larger image to see what we're talking about. This is in addition to the standard horizontal and vertical line sensitivity. This center point is capable of detecting diagonal detail along two orthogonal axes with high-precision due to a wider baseline (have a look at the drastic separation in the diagonal stripes, above). The center AF point is of particular interest, as it is a dual cross-type design (featuring both x and + shaped sensors, as seen in the vertical 5 center AF points in the 1D X and 5D Mark III). The brand new AF sensor module in the 7D Mark II ![]() This can make focusing on horizontal lines - like horizons or sometimes eyes - harder to focus on. For example, an AF point capable of detecting only horizontal detail in landscape orientation will only detect vertical detail when the camera is rotated into the portrait orientation. The ability to detect both types of detail makes for a more robust AF system. The 7D Mark II's 65 cross-type AF points are capable of detecting both horizontal and vertical detail (only 41 of the 1DX and 5D Mark III's 61 AF points are cross-type). All 65 of its AF points are cross type, with the central point being sensitive to diagonal contrast, as well as vertical and horizontal. This gives that center point a 1 EV advantage in low light compared to the 1D X and 5D Mark III.Īn approximation of the position of the AF points in the EOS 7D Mark II. Additionally, the center point is capable of focusing with lenses (or lens/teleconverter combinations) as slow as f/8, as well as down to EV -3. All of these AF points are cross-type (when using lenses with a maximum aperture of f/5.6 or faster), with the center AF point capable of high-precision, dual cross-type focusing with wider aperture (f/2.8 and faster) lenses. It features 65 AF points spread across a significant portion of the frame, with especially wide horizontal coverage. The Canon 7D Mark II introduces a brand new autofocus (AF) module inspired by the professional level AF system in the Canon 1 DX.
