Adjusting the Degree of Bokeh

Adjust the settings in steps 2 to 4 as required.

  1. Set the bokeh control function to On.
  2. Fully open the iris.
  3. Set the ND filter to 1/128.
  4. Set the gain to 0 dB and use lighting to get the correct exposure.
  5. Adjust the focus.
  6. Adjust the iris.

    The degree of bokeh changes.

Note

  • The appearance may vary depending on the operation speed, lens, shooting settings, and subject, and also the brightness may change. Performing a camera test before shooting is strongly recommended.
  • The brightness may change when the iris operation direction changes, such as when opening the iris after closing it or when closing the iris after opening it. In this case, adjust slightly more than required beforehand and then back up a little, check the brightness, and then start shooting. For example, if you want to open the iris to F8 aperture and blur the background, first close the aperture past F8 and then return to F8, check the brightness, and start shooting.
  • Perform bokeh control operations slowly. If you need to speed up the operation, try adjusting gradually while checking the changes to the image.

Hint

  • When the bokeh control function is set to On, the ND filter and gain operate together to offset changes in exposure due to iris adjustment, allowing you to change the degree of bokeh.
  • The bokeh control is first linked to the ND filter in response to the iris operation. When the ND filter can no longer be changed, the gain is linked.
  • In MF mode, it is recommended that you first open the iris and then adjust the focus.
  • If you use the auto ND filter instead of the bokeh control function, the ND filter follows the change in the brightness of the subject.

Display during gain link operation

When the bokeh control function is set to On, the gain may change as the iris is adjusted.

When the gain link is active and the gain changes, a message appears at the top of the screen and the (B) icon on the gain indicator blinks.
