.05 seconds is currently the fastest exposure time that can be set within the Oracle. However, depending on the camera settings that you are using, the exposure times set in the Oracle are really a window of time for the exposure to happen. To achieve faster exposure times you will simply have your camera set in "Manual" mode and the exposure set in-camera for the desired length.
The Oracle controller only controls the exposure time length if your camera is set to "bulb" mode.
Hope this helps. If you have further questions you can contact us at firstname.lastname@example.org for further guidance.
