Eye-controlled Focusing

Through the tracking of eyeball movements, EOS cameras equipped with eye-controlled focusing (ECF) are able to choose the appropriate autofocus point based on where the user is looking in the viewfinder frame. ECF comes especially useful in sports photography where the subject may shift its position in the frame rapidly.

EOS cameras equipped with ECF are the EOS A2E (U.S. model names are shown; see the table below for equivalents in other countries), EOS Elan IIE, EOS IXe, EOS-3, EOS Elan 7E, and EOS Elan 7NE.

Canon has not continued its use of eye-controlled focusing with its digital SLRs, however. The EOS Elan 7NE is the last EOS camera to have this function.
