Use custom functions to customize your Speed Booster/Smart Adapter. Metabones App may present certain customizable options on the firmware upgrade screen. You may also plug in a Speed Booster or Smart Adapter with up-to-date firmware to view or change these customizable options using Metabones App.
Customizable options are not displayed if you are upgrading from a very old firmware version, or if you have pressed the jog lever downward while connecting the micro USB cable.
Park focus when camera is turned off
Some lenses change length during focusing. If this option is set and the camera is turned off, the lens will park at infinity to shorten these lenses for storage. This option is ignored for some lenses. However, STM lenses always take heed of this option because they require electricity to focus but cannot be retracted by turning the manual focus ring after power off. Olympus cameras will need to have the 'Reset Lens' option under Settings A menu turned on for focus parking to work.
Changing iris on JVC/Panasonic with adapter\'s jog lever requires inward push to activate
With a JVC or a Panasonic camera, iris can be changed either on the camera body or with the jog lever of the Speed Booster or Smart Adapter. Toggle between camera iris control and adapter iris control by depressing the whole jog lever inward. In prior versions, adapter iris control is also activated by simply flicking the jog lever up or down, but this is no longer the default behaviour as of adapter firmware version 2.5. Set this option to have the pre-2.5 behaviour, which is more convenient to switch to adapter iris control but with a higher likelihood of activating it by mistake. In either case, camera body iris control is restored by pushing the whole jog lever inward.
