![]() ![]() That’s when subject detection and tracking become especially important. But when a subject moves around the frame, the active AF point/area also needs to keep up with the subject's changing position. The variety of AF modes makes it easier to acquire focus on different kinds of subjects. In its place is the Whole Area AF mode.ĭeep learning-based subject detection tracking with EOS iTR AF X Subject detection via deep learning tracking via EOS iTR AF X As a result, there is no more “Face Detection + Subject Tracking Priority AF” mode. The biggest difference from previous EOS camera models is that subject detection and tracking is possible in all AF area modes. Now enabled by default: Subject tracking, Servo AFĭue to the significant improvements to the subject detection capabilities and tracking capabilities on the EOS R3, Subject Tracking: ON and Servo AF are now enabled by default. This provides greater flexibility to set a Zone AF frame size that best suits the subject. Users can freely set the size of the Flexible Zone AF frame anywhere from a 9 (3×3) segment area to up to as large as 999 (37×27) segments, and save up to three different Flexible Zone AF area sizes. On the EOS R3, Zone AF has been enhanced and now takes the form of the Flexible Zone AF mode. Previous EOS camera models had the Zone AF mode, which limits the AF area to allow easier tracking of a target subject via an auto-selected AF point. ![]() However, as the mirrorless EOS R3 uses an electronic viewfinder (EVF), which displays the same image as the Live View display, users can expect the same fundamental AF performance regardless of whether they are shooting through the viewfinder or in Live View. On DSLR cameras, different AF systems are engaged during viewfinder shooting compared to during Live View shooting, which can cause performance to differ. ![]() Up to 100% × 100% coverage is available with almost all RF lenses-in other words, AF is possible anywhere throughout the image area. In this article, we will look at each different aspect of AF in detail.ĪF coverage and changes to AF area modes AF coverage and changes to AF area modesĪF coverage on the EOS R3 depends on the lens attached and the AF method selected. Among other improvements, Version II adds to this the ability to conduct advanced subject detection by leveraging on the powerful DIGIC X image sensor and deep learning technology.ĪF systems are complex because they require coordination between different features such as subject detection and tracking to work. Under the Dual Pixel CMOS AF system, each pixel on the CMOS image sensor is equipped with two photodiodes, allowing every pixel on the sensor to be capable of both phase difference detection as well as imaging, hence achieving both highly accurate AF and high image quality. The EOS R3 uses the Dual Pixel CMOS AF II system for autofocusing. ![]()
