I'd be interested in some experiences and thoughts on mid-range strobes.

Right now I am shooting with a Sony A6400 in a Seafrogs / Salted Line housing which I will eventually upgrade, I'd rather upgrade the strobes first, but am uncertain if I would stick to a mirrorless/APC or look to upgrade to FF, as I do prefer a smaller rig overall.

Most commonly I shoot with the Sony 10-18mm rectilinear lens behind a 6" dome or a converted Tokina 10-17mm fisheye, so focused on wide angle without any great interest in macro, at least not yet.

Most of my diving is local, however I'd still like to be able to travel reasonably easy given I do take the occasional trip and liveaboard.

I have only used old secondhand Sea & Sea strobes (YS-110a and YS-27) in manual so almost anything will be an upgrade.

In general my preference is for smaller/lower weight, <=$1000 USD per strobe and reasonable power to support wide angle shots in the context of my current system.

I would prefer 18650s or other Li-ion batteries, but I do already have plenty of NiMHs from my existing strobes so it isn't a major consideration.

With that in mind the three strobes that have got my attention are the following, but also open to others;

• Sea&Sea YS-D3

• Marelux Apollo S

• Backscatter Atom

Outside of the obvious spec differences, any particular other items to share on light quality, ease of use, etc.?

Given the long timeframe so far I'm going to assume Inon 'Z335' still isn't going to be available any time soon.

I shoot an A6100, in a Nauticam A6400 housing, with the Tokina 10-17 or Zeiss Touit 50mm macro.

I use a pair of YS-D3's and they're excellent. The snoot is great for macro, and they're plenty powerful for WA, especially with the dome diffusers.

You can also get them for $500 a piece from divervision in japan. Sea&Sea YS-D3 DUO Strobe – DiverVision Underwater Photo Equipment

Sea&Sea seems to have quite a bit of chatter around reliability/durability but unclear to me how much is because they've sold so many of them.

That is a very attractive price, I was pretty tempted by the specs of the Marelux S's but I don't know anyone who uses them, but that could change the equation a fair bit.

From what I understand, there were a lot of issues with the D2 when it came out, which was mostly resolved with the D2j release.

All I can say is I've been diving S&S strobes for 20+ years, starting with YS-25a's, then a pair of YS-110a's for many years, and now with D3's for the last few years. I personally have never had any issues, following normal maintenance, o-ring inspection and lubrication, and storage practices.
