Using focus assist
Pressing the FOCUS ASSIST button enlarges the center of the viewfinder and LCD monitor screens, or displays a bar at the bottom center of the screen. These displays make aligning the focus easier and are particularly useful in manual focus mode. The display that appears when the FOCUS ASSIST button is pressed can be configured with the FOCUS ASSIST SW item in the setting menu SW&DISP SETUP screen. (Page 106)

•In the auto iris mode, the lens iris can be corrected using this dial.
•Increase in brightness beyond the maximum aperture (OPEN) is performed via gain adjustment (CAMERA mode: 0 to 24 dB; PHOTO mode: 0 to 18 dB).
•If further gain adjustment is necessary, assign HIGH GAIN to one of the USER buttons 1 to 3. The gain mode switches between normal and high with each press of the button.
Gain can be set to up to 34 dB in high gain mode.
In PHOTO mode, switching to high gain mode is disabled.
•Set the direction of the IRIS DIAL and aperture control in the setup menus, SW&DISP SETUP screen, IRIS DIAL.
•The lens aperture can be adjusted in the focus ring by setting the RING switch to IRIS. The relationship between the direction of rotation and aperture control is based on the IRIS DIAL setting in the SW&DISP SETUP screen. However, as this will make it impossible to adjust the focus in the focus ring, please set the focus control method to A (AUTO) with the FOCUS switch. Zoom control can also be assigned to the FOCUS ring.(Page 40)
•As you shrink the aperture to a near closed state, resolution will decrease due to light diffraction. You can prevent this by adjusting the shutter speed and increasing the aperture size.
