Sea&Sea Announces YS-01 Solis Strobe
By Ian Bongso-Seldrup, April 6, 2020 @ 10:00 PM (EST)

Sea&Sea has announced an updated version of its mid-level YS-01 strobe. Unlike the recently announced entry-level YS-03 Solis, which only offers TTL flash exposure, the YS-01 Solis gives photographers manual control of the strobe’s output—in 10 increments.

The new strobe uses Sea&Sea’s DS-TTL II system, which is the same circuitry found in the high-end YS-D2J. This system gives users the advantages of TTL automatic exposure but with the ability to tweak the light level control to fine-tune output.

Sea&Sea has also improved the strobe’s target light. As well as the power being 40% stronger, the target light axis has been modified to better reflect the flash coverage. Other features are similar to the YS-03 Solis: guide number of 20, beam angle of 100° by 100°, recycle time of 1.9s (using Ni-MH batteries), and depth rating of 250 feet (75 meters).

The YS-01 Solis costs $450 and is available from Backscatter. The original YS-01 has been discontinued.

PRODUCT INFORMATION

YS-01 SOLIS

FEATURES

Equipped with the same DS-TTL II circuitry as superior Sea&sea’s high-end models

The DS-TTL II circuitry helps emit the correct amount of light automatically based upon light intensity from the camera’s onboard flash. The strobe allows you to adjust light intensity stronger or weaker from programed standard exposure. With this function, even an inexperienced underwater photographer can instinctively control the desired amount of light. Example: If you are using two YS-01 Solis strobes, one on the right and the other on the left, and there is white soft coral to the right of your photographic subject, you can just delicately lessen light intensity from the strobe on the right alone by just turning the light level control to minus. With the improved circuitry, you can realize desired lighting for all your underwater images in a breeze.

Increased light intensity from the target light

Compared with the predecessor model, lighting intensity of the YS-01 Solis’ target light is 40% stronger increasing the visibility of the light axis has improved helps you understand position of the strobe position more accurately.

Superior light distribution and wide beam angle

Because of exclusively designed prism lens, the YS-01 Solis realizes a wide beam angle of 100° x 100° with ideal flat light distribution even when the accessory diffuser is not attached. With the diffuser, light will soften and beam angle will increase to 110° x 110°.
 

Ideal flat and circular light distribution. One top light. TG5 + WCL06x
