Frequency Setting Mode Added to High-Frequency Flicker Reduction Function
A frequency setting mode has been added to the
- Once you have configured a frequency, only values that are integer multiples of the cycle of the configured frequency can be selected for the shutter speed during shooting. The shutter speed can be changed without affecting the flicker reduction effect.
- Since the frequencies of LED lighting and high-frequency LED displays vary from product to product, you can save multiple frequencies that are each tailored to a product and switch between them according to the situation.
- By default, four frequency settings are available from [PRE1] (7680 Hz) through [PRE4] (1920 Hz). The frequencies can also be adjusted.
- If you have configured a frequency, the shutter speed should be slower than 1/(frequency) s.
Switching the Frequency
Four frequency settings are available by default. By assigning [High-frequency flicker reduction] to a desired control in Custom Setting f2 [Custom controls (shooting)], you can switch frequencies while viewing the shooting display.
Assign [High-frequency flicker reduction] to a control using Custom Setting f2 [Custom controls (shooting)].
Press and hold the control to which [High-frequency flicker reduction] is assigned.
The camera will enter frequency setting mode.
Switch the frequency.
- Rotate the sub-command dial to switch between [PRE1], [PRE2], [PRE3], [PRE4], and [OFF].
[PRE1] through [PRE4] are configured to the following frequencies by default. Reduce the flicker effect by selecting a frequency suited to the light source or high-frequency LED display.
- [PRE1]: 7680 Hz
- [PRE2]: 3840 Hz
- [PRE3]: 2880 Hz
- [PRE4]: 1920 Hz
- If none of the options from [PRE1] to [PRE4] are successful in reducing the flicker effect, use a custom frequency value (0Adjusting the Frequency Value).
- Selecting [OFF] will result in the same behavior as in earlier versions of the camera firmware.
- While in frequency setting mode, pressing the shutter-release button will not take a picture.
Press J to exit frequency setting mode.
Exit frequency setting mode and return to the shooting display to enable photography.
Cautions: High-Frequency Flicker Reduction
- Even if you have configured a frequency, the effects of flicker in the shooting display may differ from those seen in photographs.
- Even if you have reduced the flicker effect by configuring a frequency, the flicker effect may return after changing the shutter speed.
- We recommend that you take test shots to identify the shutter speed that minimizes flicker and banding.
Adjusting the Frequency Value
The frequencies configured for [PRE1] through [PRE4] can be adjusted.
Press and hold the control to which [High-frequency flicker reduction] is assigned to enter frequency setting mode.
Select an option from [PRE1] through [PRE4] to adjust the frequency.
Press the DISP button.
Enter the frequency value.
- Press 4 or 2 to highlight digits and press 1 or 3 to change.
- The frequency can be set between 30 and 9999 Hz.
Press the DISP or the J button.
- Press the DISP button to save the frequency and return to frequency setting mode.
- Press the J button to save the frequency, exit frequency setting mode, and return to the shooting display.
Using the Photo Shooting Menu
The frequency can also be configured from [High-frequency flicker reduction] in the photo shooting menu.
Highlight [High-frequency flicker reduction] in the photo shooting menu and press 2.
Highlight [On (shutter speed fine-tuning)] and press 2.
The setting of the currently selected frequency will be displayed.
Select the frequency from [PRE1] through [PRE4], or [Off].
Press the J button to save the frequency and return to the menu.
Adjusting the Frequency from “High-Frequency Flicker Reduction" in the Photo Shooting Menu
Highlight an option from [PRE1] through [PRE4] in [High-frequency flicker reduction] > [On (shutter speed fine-tuning)] and press 2 to adjust the frequency.
- Press 4 or 2 to highlight digits and press 1 or 3 to change.
- The frequency can be set between 30 and 9999 Hz.
- Press the J button to save the frequency and return to the menu.
Resetting Frequencies to Default Values
The values for all options ([PRE1] through [PRE4]) can be reset using [High-frequency flicker reduction] > [On (shutter speed fine-tuning].
- Press O (Q), highlight [Yes], and press J to reset the frequencies to their default values.
