THE NEXT GENERATION YS-D2 STROBE OFFER EXCLUSIVE FEATURES LIKE NO OTHER STROBE IN THE WORLD.
BUILDING ON THE GREAT PERFORMANCE SPECS OF THE YS-D1, THE YS-D2 HAS ADDED AUDIBLE CONFIRMATION, PROVIDING TTL CONFIRMATION AND READY LIGHT CONFIRMATION. THE YS-D2 NOW ALSO FEATURES A REAR ILLUMINATED PANEL WITH EASY TO READ CONTROLS.
* Rear Illuminated Control Panel
* Audible Confirmation
* Dual Powered Target Light wit Red Filters included
* New Control Knobs
* New Design Battery Compartment
* Wing-Nut style fixing bolt
* Recycle time: 1.5 sec. with NiMh Batteries (The YS-D1's recycle time was 1.9 sec.)
* DS-TTL ll system's accuracy and stability have further improved (from the YS-D1)
* Exposure compensation: +/- 2EV. (The YS-D1's exposure compensation +/- 1.5EV)
* Information panel on rear (mode, guide number, exposure compensation) is now illuminated by a backlight so you can now check settings with ease, even in dark conditions.
* Controls have been made bigger, for easier opperation even when you are wearing a pair of thick gloves.
* Built-in target light is even brighter (compared with the YS-D1) and now has two power settings. Red filters also included for target light.
Colour of illumination changes to indicate mode: Aqua Blue (in DS-TTL mode), Blue (in Slave TTL mode), Orange (in Manual Pre-Flash mode), Green (in Manual mode without Pre-Flash) and White (in Custom mode). You can check which mode the strobe is set even under pitch-black conditions.
SLAVE TTL MODE
MANUAL PRE-FLASH MODE
MANUAL NON PRE-FLASH MODE
The YS-D2 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.
(*1) when nickel hydride AA batteries are used.
DS-TTL II MODE
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-D2.
(*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.
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).
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 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.
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.
Some manufactures use their own pre-flash timings on their cameras. The new custom function means the YS-D2 can be compatible with cameras with non-standard pre-flash in DS-TTL and manual modes.
The strobe can be attached to an arm with the YS-mount or the ball-mount (both mounts included as standard accessories).
In accordance with the camera and housing you use, choose either a fiber-optic cable (optional) or sync cord (optional) to connect the strobe.
* A Fiber-optic cable ll is required to use the DS-TTL ll function.
