One of the challenges of shooting with very wide apertures is nailing that perfect focus. You have millimeters of room for error— aka almost nothing! Even with the steadiest and experienced hand, shooting below f/2.8 can be a challenge, not to mention f/1.4! When shooting very wide aperture portraits, as the subjects move or you recompose, it’s not easy.
This, however, is where one of the fantastic features of the EOS R really starts to help make my life a lot easier—Face Tracking and Eye Detection Autofocus!
In Single Shot mode with Face Tracking on, the camera will automatically determine my subject’s face and lock focus. Even better, if I enable Eye Detection it will lock focus EXACTLY where I need it: my subject’s eyes! Even better than that—if the subject is turned to the side, it locks focus on the eye closest to the camera! If for any reason you want to switch eyes, you can toggle back and forth between them.
Undoubtedly my percentage of shots in focus at f/1.4 has increased astronomically because of this feature. Here is a portrait taken using eye detection and shot with the 85mm at f/1.4 (wide open). You can see even when zooming in that the focus is exactly where it needs to be (though check out that super narrow depth of field!).
