Sea & Sea YS-D2J Overview

  • 1Description

Illuminate the underwater world in rich, natural color at depths up to 328' with the yellow YS-D2J Underwater Strobe from Sea & Sea. It features a guide number of 104' / 32 m on land at ISO 100; this value changes to 65' with the supplied Diffuser-120, or 78' with the supplied Diffuser-100. The flash has a beam angle of 80 x 80°, which is widened to 100 x 100° with the Diffuser-100 and 120 x 120° with the Diffuser-120. A daylight-balanced color temperature of 5600K enables the strobe to restore colors that are absorbed underwater, thus allowing for more vibrant and accurate images.

Both TTL and manual flash exposure modes are available on the YS-D2J. Unlike the previous model, the YS-D1, this strobe features audible and ready-light TTL confirmation. Additionally, the rear side of the unit has a glowing panel with easy-to-read controls, which will be helpful in low-light situations. The YS-D2J is configured with a 5-pin sync cord connector and a fiber-optic port for connection to an underwater camera housing. It is powered by 4 AA Alkaline or NiMH batteries.

Guide Number
  • 104' / 32 m on land at ISO 100
  • Changes to 65' with the supplied Diffuser 120 or 78' with the supplied Diffuser 100
  • Beam angle of 80 x 80°
  • Widened to 100 x 100° when used with Diffuser-100 and 120 x 120° when used with Diffuser-120
  • Diffusers help create soft, even light to reduce glare, backscatter, and hard shadows
Color Temperature
  • Daylight-balanced color temperature of 5600K enables the strobe to restore colors absorbed underwater for more vibrant and accurate images
  • With diffuser in place, color temperature is reduced to 5250K, which is still close to daylight-balanced
Target Light
  • Included LED target light with red filter helps you avoid disturbing the skittish sea life that is likely to be alarmed by normal light. It is fitted inside the diffusers
  • Target light's output is adjustable in 2 steps: 100-300 lumens
  • Automatically turns off when strobe fires and turns back on after 0.5 sec
Depth Rating
  • Safe for use at depths up to 328'
  • Features over-pressure relief valve
Controls, Modes, and Operation
  • Both TTL (DS-TTL and slave TTL) and manual flash exposure modes are available
  • Sea & Sea's DS-TTL II system has been improved, with an added function that stabilizes light emission by controlling voltage differences--so variability of intensity will not be evident during continuous firing
  • Accuracy of TTL exposure has been increased, and images are less likely to be overexposed
  • EV control function can fine-tune amount of light emitted. Exposure compensation range has been improved to +/- 2.0 EV: -2.0, -1.5, -1.0, -0.7, -0.3, +0.3, +0.7, +1.0, +1.5, +2.0
  • Custom function allows for compatibility with cameras that have non-standard pre-flash in DS-TTL and manual modes
  • Illuminated control panel for good visibility in dark conditions
  • Color of illumination changes to indicate mode: aqua blue for DS-TTL, blue for slave TTL, orange for manual pre-flash, and green for manual mode without pre-flash
  • Large knobs and magnetic rotary switch enable improved handling and fast operation, while helping to prevent accidental activation/deactivation
Power Source
  • Recycle time is about 1.5 sec with NiMH batteries
  • Flash features audible charge signal
  • Configured with a 5-pin sync cord connector and a fiber-optic port for connection to an underwater camera housing using an optional cable
  • Fiber-Optic Cable II from Sea & Sea is required to use DS-TTL ll function
  • YS and ball mounts included for attachment to lighting arms

    Sea & Sea YS-D2J Reviews

    YS-D2J Underwater Strobe (Yellow) is rated 3.6 out of 5 by 5.
    Rated 4 out of 5 by from Improved technology over Use two ys-d2 with TTL Y-cables for a Sea&Sea housing for a Nikon D7000. Replace two y-120's. Plus - works perfectly with current cables and attachments. Weighs less and uses only 4 AA batteries each (versus 8 on older Sea&Sea equipment). Attaching gear appears more durable and offers choice of ball or bolt to attach strobes to system. Similar, simple on/off as older equipment AND different colors on back of strobe based on whether you're in manual/optic cable/TTL mode :). minus - arrived with one of the diffusers spread so that it could not be attached. on TTL setting, color on back panel changes for light blue to dark blue when Y-cable is attached - dark blue indicates strobe is in slave mode. Somewhat confusing, but TTL works correctly.

    Rated 1 out of 5 by from Died after 15 dives My YS-D2 died shortly after the warantee expired.? It could not be repaired, and the company did nothing to make it right.? This has happened to many others.? This strobe has gained a deservedly terrible reputation, and the company along with it.

    Rated 5 out of 5 by from Lighter and better than my previous strobes - Recommend Amateur Scuba photographer using a Nikon D7k with S&S housing. Use a 'Y' sync cord w/2 strobes and TTL wire. These strobes have more power than previous strobes and used the included diffusers to 'cool' most shots. 3 items:1. Op/Ed - The 'modelling' light was not much use, even at night. I attach a separate light to my housing and it only requires that I move it up/down to center on subject. Also the modelling light isn't near bright enough for daytime and you must place strobe where you want the modelling light to use it.2. FYI - Attaching a TTL sync cord precludes the use of the 'slave' setting. 3. New/Improved - Attachment to extension arm is improved, both engineering and material. Choice of 2 mechanisms and much sturdier/stronger. (Last S&S strobe broke and had to epoxy together).

    Rated 5 out of 5 by from Good strobe Item arrived promptly in good shape. So far I have used it for only a couple of dives, but it performed well. In TTL mode with an Olympus E-M! in a Nauticam housing, the exposures were good if sometimes a tad bright. I'll play with some of the many adjustments next time. Very happy with the purchase.

    Rated 3 out of 5 by from Replaces D2 that leaked in cable connection. Hope the D2J is better built from Japan and not from where ever the D2 was built. Give Sea and Sea one more chance. I have one more D2 left. If it craters I'll move on to some other Manuf.

    can you please advise what fixing accessories are already included in the pack? Is fiberobtic cable included?
    Asked by: nidai i.
    Nidai i . I bought the YS-D2 strobe from B&H. I attached the included ball mount at the bottom of the strobe. I then bought strobe arms from ultra light control systems to attach the strobe to a ball on my underwater housing. You have to buy the fiber optic cable separately.

    If I use this strobe for my Olympus TG4 + Olympus Housing, will I be able to use the TTL function using just an ordinary fiber optic cable? if not, which cable should I use? Thanks!
    Asked by: Daniel D.
    Yes. Just purchase the fiber optic cable in the length that your set up requires.

    I have a YS-D1 and am considering a second light with my Olympus OMD EM5/Nauticam rig: since the D1 has been discontinued, is there any reason I cannot/should not add the D-2?
    Asked by: Anonymous
    Go for it. The D2 is a great strobe.

    Will this strobe fit well on my Iklite house for the Olympus TG4 housing
    Asked by: Anonymous
    If your housing permits the onboard flash to work and you can see the flash from outside the housing, you can use a YS-D2. You will need a fiber optic cable and masking kit.

    how does the modeling light affect battery life? Can I just leave it on throughout the dive?
    Asked by: Robert
    I estimate that you will cut the battery power available for photos in half if you leave the modeling light on high throughout the dive. I conducted a test for you by comparing the mah needed to recharge the batteries. Initially, I turned on the strobes for an hour and then recharged the batteries while measuring the energy replaced. I repeated this test with modeling light on high. When recharging the batteries after using the modeling light, they required twice as much to recharge.
