HM4x H730 You can use [Camera] > [Day/Night Mode Focus] > [Compensate for light source] to focus according to the wavelength of an infrared light (P. 107). H730 [One-shot AF] HM4x H730 S30 Use when [Focus] is set to [Manual]. When you click [Exec], the camera will focus once using autofocus and then switch to manual.

[Auto] Automatically controls the exposure. [Auto (Flickerless)] Automatically adjusts the shutter speed according to the brightness of the usage environment. Video flickering caused by fluorescent lights, etc., is reduced. [Auto (Flickerless2)] S30 S31 S80x S90x Use this mode if you cannot achieve the desired flickering reduction even after selecting [Auto (Flickerless)]. However, the appropriate exposure level may not be applied (causing excessive brightness) because the range of automatic shutter speed adjustment cannot exceed 1/100 seconds while using this mode. Important S30 S31 S80x S90x Unstable light sources may still cause flickering on the screen, even if you have selected [Auto (Flickerless)] or [Auto (Flickerless2)].

[Auto (Aperture-priority AE)] HM4x H730 Automatically adjusts the gain and shutter speed according to the specified [Aperture]. [Manual] Manually set [Shutter Speed], [Aperture] ( HM4x H730 ), and [Gain]. Cannot be set when [Smart Shade Control] is set to [Auto]. [AGC Limit] Select the Auto Gain Control (AGC) limit value for increasing gain to brighten video in low light conditions. The greater the value, the higher the sensitivity will become, but video noise will increase. Important • [AGC Limit] will not function if [Exposure] is set to [Manual], [Auto (Flickerless)], or [Auto (Flickerless2)] ( S30 • Minimum subject illumination may change when [AGC Limit] is set.
