Key Features

Compact Without Compromise

Despite its small size, the S-2000 delivers performance comparable to much larger underwater strobes. Its compact design makes it especially well suited for compact cameras, mirrorless systems, and lightweight travel rigs while remaining powerful enough for DSLR systems.

S-TTL Automatic Exposure

The built-in S-TTL Auto mode automatically adjusts flash output based on your camera's pre-flash, helping you achieve well-balanced exposures with minimal setup. It's perfect for photographers who want reliable results while focusing on composition instead of flash calculations.

Full Manual Control

When you want complete creative control, the S-2000 offers 12 manual power levels in ½-stop increments, allowing you to fine-tune lighting for macro photography, backlighting, and creative effects.

Wide, Even Coverage

The strobe provides:

• 105° × 95° beam angle without the diffuser
• 110° circular coverage with the included diffuser

This wide beam is ideal for illuminating reef scenes, fish portraits, and close-focus wide-angle images.

Fast Recycling

With compatible rechargeable AA batteries, the S-2000 can recycle in approximately 1.5 seconds, allowing you to capture fast-moving marine life without long delays between shots.
