Sea & Sea YS-01 Solis Strobe

This affordable, compact underwater strobe makes TTL strobe photography accessible and enjoyable for everyone. Its user-friendly design ensures ease of use, allowing anyone to capture stunning underwater images.

Sea & Sea YS-01 Solis underwater strobe

The Sea & Sea YS-01 Solis Strobe is one of the latest addition to Sea & Sea strobes. Lots of great improvements have been made from its predecessor, YS-01 but still retained the small and compact footprint which is great. This is great for compact, mirrorless and amateur DSLR users. It is very easy to use and has TTL capability.

Featuring high-end DS-TTL circuitry at an affordable price

Unlock the full potential of your underwater photography with our cutting-edge DS-TTL II circuitry. This advanced technology automatically adjusts the emitted light based on the intensity detected from your camera's onboard flash. Now, you have the power to fine-tune the light intensity to your liking, whether you want it stronger or weaker than the standard exposure.

Sea & Sea's innovative strobe is compatible with any camera that has a pre-flash and a TTL flash exposure function, regardless of make. This means you can seamlessly integrate the YS-03 SOLIS into your existing underwater photography setup, without any compatibility issues.

Simple Controls

Experience the ultimate simplicity in underwater photography with the user-friendly YS-01 SOLIS. Designed with every photographer in mind, this strobe is easy to understand and operate. With just one control—the rotary power switch—capturing stunning images is as simple as turning the switch from OFF to TTL.

Superior light distribution and wide beam angle

Discover the exceptional capabilities of the YS-01 Solis, featuring an exclusively designed prism lens for unparalleled performance. With its advanced design, this strobe achieves an impressive wide beam angle of 100°x100°, ensuring ideal flat light distribution even without the need for an accessory diffuser.

If you desire a softer lighting effect, simply attach the diffuser to enhance the experience further. The diffuser not only softens the light but also increases the beam angle to an impressive 110°x110°, providing even more coverage for your underwater photography.
