- Page 2 Safety Warning for Batteries usage ➢ Use only batteries of the type specified in the Specification. ➢ Batteries must be new and undamaged. Carefully check batteries before usage. ➢ To avoid leakage or explosion, always check appropriate battery terminals position (“plus” terminal up) before installing to the TTL Converter.
- Page 3 Battery energy saving ▪ IMPORTANT! Set an acceptable small “Standby Timer” (or “Power Off Delay”) and other small times of camera activity (time for image viewing, menu displaying time etc.) in camera menu. This is important for TTL Converter battery saving. When camera is in Standby mode or switched OFF, the TTL-Converter is switched OFF automatically.
- Page 4 Set necessary synchronization for the flash, using menu “Flash mode” (“Flash Synchronization Mode”). The most popular sync mode is “Fill Flash”, it means “Front curtain” synchronization (1-st curtain sync). So, for beginning, please set “Fill Flash” (1 curtain sync). Later, as an option for special creative shooting, you also can set “Rear-curtain sync” (“2-nd Curtain sync”) mode. This option is supported by TTL-Converter as well: For shooting in TTL flash mode user should set a desired maximum “Flash sync speed”...
- Page 5 (in M-mode of camera controls). The automatic modes and semi-automatic modes (A, T, P etc.) also can be used by experienced users. But in common case, the fully automatic or half-automatic modes of setting Aperture/Shutter/ISO are not recommended for underwater shooting, because of unpredictable results in underwater conditions. Set recommended Aperture in range F8-F16 for Wide-angle photo, or F16-F22 for Macro photo, as initial settings.
- Page 6 Shooting in MANUAL flash mode TTL-Converter supports 2 different variants of manual flash mode (described below in detail): Manual Flash Mode set via camera menu (“Auto FP” command usage, flash intensity also can be adjusted via camera menu), Manual Flash Mode at rotary switch “0” position (When TTL Converter rotary switch is in “0” position, the communication protocol with camera is disabled).
- Page 7 Manual Flash Mode at rotary switch “0” position: ▪ Switch system to Manual mode by setting TTL-Converter onboard rotary switch to “0” position. ▪ This operation can be done only before submerging, when underwater housing is open. ▪ TTL protocol communication is totally disabled in this case. The symbol “Flash” disappears from camera service screen.
- Page 8 underwater strobes are not recommended for Continuous (Serial) Shooting in TTL mode. The 1 shot will have normal exposure, but the next shots will have different lighting or none at all. The effect strength depends on specific strobe’s capabilities. ▪ Large size underwater strobes (like YS-250, DS-162 etc.) have bigger size main capacitor inside, which contents much more energy.
