Welcome, I'm Dethi from RamLite and today I'll be talking to you about the new stage of the I-40TL. RamLite's IFL-TTL is compatible with Canon or Nikon DSLR and mirrorless cameras that are equipped with a hot shoe. It is an all-powerful stroke lighting system with compact design DC battery pack and AC power supply pack. It supports E-TTL 2, the Nikon I-TTL with great performance. The RamLite's accumulated T-TL technology supports idealized exposure value anywhere under any environment. It also comes built in with the innovative RamLite's TSV wireless system. The optimized user interface, visible color LCD display and compact design supports very easy operation and logical T-TL performance. Very mild at the T-TL and HSS mode should only be used with the TSV wireless controller and trigger. To synchronize the TSV wireless trigger and IFL-T, simply switch on the IFL-TTL, press the mode button once on the TSV wireless controller and you're ready to go.
