greenspun.com : LUSENET : Canon EOS FAQ forum : One Thread

A simple silly question. How do you set the AF to Center Cross? Thanks.

sorry,i dont't understand actually what u asked.i cannot answer your question exactly because u didn't tell which model it is. what i can tell u is just that the AF of my eos300 can be manually set at the central cross sensor by pressing the focusing-point- selection button and then turn the command dial until a central 'black box' appears at the LCD.

You select the centre AF point, you can't select cross/horizontal/vertical or whatever the other focus points are.

I guess I misunderstood. Some posters referred to the Center Cross Sensor(s). I took that to mean they somehow selected the 5 central sensors. I realize the choice is all or 1.

The first generation of EOS cameras could only autofocus if you gave them a straight line to go on - usually a vertical line. These autofocus sensors, therefore, only operated in a single plane.

Canon by the early 90s had developed a "cross sensor" which is capable of sensing both horizontal and vertical lines. EOS cameras with multiple sensors usually have a cross sensor in the middle - the other sensors usually require a horizontal or vertical line.
