Lenses and Usable AF Points Although the camera has 61 AF points, the number of usable AF points and focusing patterns will differ depending on the lens. The lenses are thereby classified into eight groups from A to H. Check which group your lens belongs to. When using a lens in Groups F to H, fewer AF points will be usable. When you press the button, the AF points indicated by the mark will blink. (The / / AF points will stay lit.) Both "Extender EF1.4x" and "Extender EF2x" apply to all the I/II/III models.
