Product Description

Sea_&_Sea.gif

Included Accessories: Fixing bolt, Diffuser100, Diffuser120, Ball Mount Strobe Adaptor.

The YS-D1 sets a new standard for underwater strobes. From subtle light output as low as Guide Number 1 to a maximum power of Guide Number 32, control of underwater lighting has become effortless. 

COMPACT BUT POWERFUL....  

Compared to the YS-110Alpha, the YS-D1 is 1EV more powerful, 50g lighter and 10% smaller. The YS-D1 is robust enough for wide-angle photography and is ideal for macro photography which requires delicate light level control. 

Power/Angle of Coverage:

The YS-D1 is supplied with two diffusers; 120 and 100. These are used individually to widen the angle of coverage and reduce the power output of the strobe. 

GN20 - 120o (with 120 Diffuser)

GN24 - 100o (with 100 Diffuser)

GN32 -   80o (without diffuser)

[Guide Number (ISO 100/m) (Land)] 

Three beam angles can be selected in accordance with the photographer’s requirements. In macro photography when a wide beam is not necessary, no diffuser should be attached. For an even strong circular 100x100 light output is desired, mount the Diffuser 100. When a wide-angle lens is used, the diffuser 120 should be attached. 

VERSATILE....  

Compatible with Most Digital Cameras 

Three TTL Circuits:

DS-TTL II

Slave TTL

Conventional Nikonos Type Circuitry 

Slave Triggered and Hardwired:

Compatible with Fibre Optic Cable Type-L and 5pin Sync Cable/N 

Equipped with Sea&Sea's new slave TTL system:- DS-TTL II, and the first slave TTL strobe equipped with an exposure compensation (EV) control. 

DS-TTL II

Revising the algorithms used for the DS-TTL system, the YS-D1 employs a totally new slave TTL system. The strobe can adjust the interval between the pre flash and the primary flash in order to be compatible with a wide-variety of cameras, if not all, on the market today. The strobe is equipped with DS-TTL ll mode which is more responsive, more precise and more reliable. The DS-TTL ll enables a variety of strobe sync photography such as slave TTL and slave manual (11 steps) with compact or digital SLR cameras. When used with a digital SLR camera in housing, the strobe can also be connected with a conventional sync cord and through a YS Converter for TTL strobe photography. In a clear water environment, two YS-D1 strobes in DS-TTL ll mode provide perfect lighting. When you would like to emphasize contrast, setting the main strobe in DS-TTL II mode and the secondary strobe in manual mode (11 steps) offers flexibility without limiting control. 

Exposure Compensation (E/V)

By controlling the actual flash light level, the strobe realizes accurate exposure compensation with EV value. Regardless of a compact or a SLR camera, you can achieve any desired exposure compensation. However, many TTL systems are not reliable. The YS-D1’s DS-TTL exposure compensation function allows users to adjust the light level in TTL mode (-1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV). 

ERGANOMIC DESIGN.... 

Simple controls and configuration enables easy operation. 

Three Colour LED Indicator light on rear:

Ready Light: Red

Slave TTL Ready Light: Blue

DS-TTL II Conformation Light: Green 

No Slave On/Off Switch:

The YS-D1 will auto-sense when a sync cord is connected, the slave ON/OFF switch will no longer be active.  

Light Level Control Dial Positively Clicks into Position:

The light level control ratchets/clicks to aid in setting and operation. 

Optional Strobe Mounts:

With the conventional YS adaptor, the strobe can be moved only upward and downward. However, with the included optional Ball Mount the strobe can be moved in a variety of angles. 

INNOVATIVE, CREATIVE BUT TRADITIONAL.... 

Features:

LED Modelling Light

Over Pressure Relief Valve

Auto Power Off Function

Pre-Flash Cancellation Mode 

UNRIVALED PERFORMANCE....
