Sea&Sea YS-D1/YS-D2 Not Designed For High Speed Sync

11 November 2015 - 03:28 AM

On a recent trip to Indonesia, I experienced what appeared to be a sync problem with my rig. Olympus E-M1 and Sea&Sea YS-D1 strobes. Looking to get a black background, I switched the camera from 1/200th to 1/250th. The result was a half exposed image. Searching the web, I found a thread from July 2014 on Wetpixel discussing the problem (http://wetpixel.com/...showtopic=53721). While a number of alternate setting combinations were discussed, there was no clear comclusion. My own feeling was that I shouldn't have to manipulate a number of settings in order to bump the speed and get a full image. Sure, changing other settings in conjunction might produce a better image. The two images demonstrate the problem. They're not particulary good in many aspects, but were shot of the same subject, the same distance, etc.. The only difference being one at 1/200th, the other at 1/250th.

I sent a query to Sea&Sea describing the situation. Their response is pretty clear:

 

Hello Bob,

  The SEA&SEA YS-D1 is designed to work with flash sync speeds up to 1/200. The strobes are not equipped for “high speed sync”, sync speeds greater than 1/200 sec. The strobe timing will not pair higher than 1/200th of a second, leaving a portion of the image dark. There is no update at this time if SEA&SEA will produce strobes capable of high speed sync.

Thank you for your inquiry,

I followed up by asking about the new YS-D2. Their response was the same:

 

 

Hello Bob,

  I am sorry to inform you that the SEA&SEA YS-D2 will not sync in speeds higher than 1/200.

Thank you,

So it's pretty obvious that for those of us looking to achieve those stunning black background shots by using high speed strobe / small aperture shots, Sea&Sea YS-D1 and YS-D2 strobes are not the ones to use.

 

If I had found this post before I bought my Sea&Sea YS-D1s, to replace my Inon S-2000s, I wouldn't have bought them. Maybe this information will help some of you.

Cleaning External Glass (Ports, Diopter, etc.)

05 November 2015 - 07:13 PM

Just finishing up a trip to Indonesia. While packing up my gear, I noticed a film on all my external glass. The water in Ambon was pretty scummy. I'm looking for suggestions to clean the glass without messing up any coatings that may be on the glass, particularly my CMC.

 

Thanks,
