Experience the power of focusing by sight . As the first EOS Digital Camera to feature the Eye Control AF , the EOS R3 redefines the limits of focusing speed and accuracy . Direct the AF point with your eye by looking at the desired subject through the viewfinder to achieve focus . The Eye Control AF is highly recommended in situations with multiple subjects as it provides a high degree of flexibility in switching focus quickly from one subject to another . When combining it with other AF tracking modes , the Eye Control AF allows split-second focus acquiring and tracking of dynamic scenes , especially when shooting unpredictable subjects that may enter or leave the frame in an instant .
