■ Changes to the Effective f-number

With this lens, the higher the reproduction ratio (the shorter 
the focus distance), the darker the image that falls on the 
image sensor and the higher the effective f-number (see the 
figure on page 162). The camera automatically compensates 
for this effect when metering exposure or adjusting flash 
output using TTL flash control, and shows the adjusted value 
for aperture in the control panel and viewfinder displays.

■ Built-in Flash Units

When using the built-in flash on cameras equipped with a 
built-in flash unit, shoot at ranges of 0.6 m (2 ft) or more and 
remove the lens hood to prevent vignetting (shadows created 
where the end of the lens obscures the built-in flash).

■ The Lens Hood

The lens hoods protect the lens and block stray light that 
would otherwise cause flare or ghosting.

When attaching or removing the hood, hold it near the 

 

symbol on its base and avoid gripping it too tightly. 
Vignetting may occur if the hood is not correctly attached.

The hood can be reversed and mounted on the lens when not 
in use.  When the hood is reversed, it can be attached and 
removed by rotating it while holding it near the lock mark (

—{

).

Align the lens hood lock mark (—{) with the 

lens hood mounting mark (●) on the lens
