| The YS-90TTL Duo is a great primary strobe and it's cordless TTL function makes it the perfect secondary strobe.
The changeable sync cord allows the YS-90TTL Duo to be used with most underwater photographic systems. Loaded with SEA&SEA's technology and quality the YS-90TTL Duo is one of the most versatile underwater flash units available. The YS-90TTL Duo can be used for all applications including wide-angle and macro photography. It includes the SEA&SEA prismatic diffuser in front of the flash tube to create even higher intensity light in an even oval pattern. The color temperature is close to that of the sun (5,400K) and provides a natural color tone for photography even in dark water. The YS-90TTL Duo's built-in Duo circuit responds to N-type (used in MMIII) and S-type TTL circuits, both used in SEA&SEA housings. Moreover, its TTL slave function enables cordless dual TTL photography, requiring only the primary strobe to be connected to the camera or housing. The guide number is 22 (land). It has 2-step (1/2 and full) light level control. Use of the accessory diffuser softens the light and helps reduce backscatter. The accessory diffuser reduces the light output by one f-stop, combined with the power control to give 4 steps of control. 2400mAh Ni-MH batteries will provide 300 full flashes over their lives at a recycle time of 1 second. It recycles almost immediately after a TTL flash, so you won't miss the chance to capture that next great image. |
