Using the focus ring design

The manual focus mechanism of this camera reads the direction and distance the manual focus ring is moved and drives the focusing lens with a small motor. Even when the camera-to-subject distance displayed in the monitor is 20 cm (8 in.) or ∞ , the focus ring can be turned farther, but stops at

20 cm (8 in.) or ∞ .

Note

•When the camera is set in the macro mode, if you set the focus mode switch to the MF position, the camera is automatically released from the macro mode .
