More info

Excellent night-time visibility. The illuminated control panel is ideal for night diving

Color of illumination changes to indicate mode: aqua blue (in DS-TTL mode), blue (in slave TTL mode), orange (in manual pre-flash mode) and Green (in manual mode without pre-flash). You can check which mode the strobe is set even under pitch-black conditions.

The YS-D2J is powerful enough to illuminate a wide area, even under very bright conditions with plenty of natural sunlight. During macro photography, where subtle exposure control is required, manual mode can easily be selected and the guide number quickly adjusted as low as 1.

DS-TTL ll automatic exposure control with improved accuracy and stability

SEA&SEA’s own automatic exposure control system, DS-TTL ll, has been further improved. Tuning light emitting timing in detail and adding light emission detection function (*2), the accuracy of automatic TTL exposure has been noticeably improved. Previously, TTL photography was difficult with the lens’s aperture wide-open (maximum aperture) and images were likely to be overexposed. It is now possible to give a low powered flash so the correct exposure can be easily achieved with the YS-D2J.
(*2) When the YS-D1 strobe is fired continuously, variability of light intensity (caused by voltage differences of the main condenser) could be evident. The new function will stabilize light emission by controlling the voltage differences.

EV control function can finely tune the amount of light emitted

By controlling the actual flash light level, the strobe achieves accurate exposure compensation with EV compensation. As the exposure compensation range has improved to +/- 2.0 EV, users can concentrate on shooting even more creative images. (-2,0EV, -1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV, +2.0EV).

Two diffusers and red filters included with the strobe as standard

By attaching one of the included diffusers, the beam angle is increased to 100o or 120o (circular) with a soft and even light. The red target light filter helps avoid disturbing skittish creatures that are likely to react to normal light. The red filter is fitted inside the diffusers.

The target light can be adjusted in 2 steps

The strobe is equipped with a target light (approximately 100/300 lumen). In use (target light switch in ON position), the light will be automatically turn off when the strobe fires and will automatically turn back ON after 0.5 sec.

Ergonomically improved controls

Handling is greatly improved. Larger knobs and a new magnetic rotary switch help prevent controls being accidentally reset in use. With the new controls, quick operation is possible when photo opportunities suddenly appear.

Custom mode is a new innovation which allows the YS-D2J to be compatible with cameras with non-standard pre-flash settings

Some manufactures use their own pre-flash timings on their cameras. The new custom function means the YS-D2J can be compatible with cameras with non-standard pre-flash in DS-TTL and manual modes.
