The Sea & Sea YS-01 is a small compact strobe with a guide number of 20 that is perfect for beginners and compact shooters. An excellent choice for both wide angle, with it’s 100 degree circular beam angle and macro shooters who will love its small size. The YS-01 can be used in either TTL mode or manual allowing you to make incremental adjustments on the fly in order to get the perfect illumination for your shot. This is the perfect solution for underwater photographers looking to make the first step in taking their images to the next level. All in a small lightweight package that is super travel friendly.

  • The Sea & Sea YS-01 Strobe is a compact yet powerful strobe that can be used with multiple modes: DS-TTL, manual, TTL with converter. It can also be used as a Slave flash.
  • The strobe had a guide number of 20 and utilizes a fiber optic cable connection.
  • An external flash is your most important accessory for UW photography. The ocean is one big, blue filter. As you descend, the reds and oranges quickly become muted shades of blue and gray. This strobe light will bring back your subjects’ natural colors.
  • With its circular beam angle of 100 x 100° and a guide number of up to 20 it is the perfect strobe for compact cameras as well as mirrorless.
  • The DS-TTL (Digital Slave TTL) feature gives you automatic exposure control when shooting in slave mode.
  • For finer lighting control it is best to shoot in Manual Mode. Using Manual Mode is easy since the YS-01 has a ten-level power dial located on the back of the strobe.
  • The YS-01 has a bright 1W LED target light to point at the target; it is bright enough to be used as a dive light on night dives.
