These focusing sensors are geared to obtain 
higher precision focusing for lenses with a 
maximum aperture of f/2.8 or faster. A diagonal 
cross pattern makes it easier to focus subjects 
that may be difficult to focus. They cover the five 
AF points vertically aligned at the center.
These focusing sensors are geared to obtain 
high-precision focusing for lenses with a 
maximum aperture of f/4 or faster. Since they 
have a horizontal pattern, they can detect 
vertical lines.
These focusing sensors are geared for lenses 
with a maximum aperture of f/5.6 or faster 
(greater than f/5.6 but not exceeding f/8 with an 
extender attached). Since they have a horizontal 
pattern, they can detect vertical lines. They 
cover the three columns of AF points at the 
viewfinder center.
