SEA&SEA YS-D2 Strobe

0.00

The Sea&Sea YS-D2 Strobe is excellent night-time visibility, the illuminated control panel is ideal for night diving.

Colour 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.

Maximum guide number is a powerful 32 (ISO 100, meter). Recycle time is only 1.5 sec(*1)

The SEA&SEA YS-D2 strobe 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 own automatic exposure control system, DS-TTL ll, has been further improved. Tuning light emitting timing in detail and adding light emission detection function, 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-D2.

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.
