12. Hood
Attaching the Hood
Loosen the hood lock knob by turning it
counterclockwise. Fit the hood onto the lens’s
hood mount, and tighten the lock knob to fix it in
place securely.
To stow the lens, reverse the lens hood and slip
it over the lens.
11. Infinity Compensation Mark
To compensate for shifting of the infinity focus
point that results from changes in temperature,
there is a margin at the infinity (
∞
) position.
The infinity position at normal temperature is the
point at which the vertical line of the distance
scale L mark is aligned with the distance index.
O O
For accurate focusing in MF on subjects at
infinity distance, look through the viewfinder or
at an enlarged image on the LCD monitor* while
turning the focusing ring.
* On cameras capable of Live View shooting
The custom lens hood cuts out unwanted light
and protects the front of the lens from rain,
snow, and dust.
