Olympus UFL-3 - does anyone actually use one?

26 February 2015 - 09:03 AM



when I use my Olympus OM-D E-M5 topside with the small on-camera strobe in "fill" mode (=TTL), strobe exposure is 100% perfect. 


But when I use it u/w with my two Inon Z240 (S-TTL), the results are... mixed, at least. With f/2.8 or f/4 the pics are always too bright, with f/16 or smaller they are too dark, even when the strobes are very close to the subject. That's not what "TTL" should be like.


So kinda out of frustration, I started using manual strobe settings with my new digicam. (I am talking about macro, of course. For wide angle I use manual strobe settings exclusively.) It does work, of course, but is sometimes a bit annoying.


In my "analog days" TTL exposure was something I never had to think about - it just worked, and it was sooo convenient. 


I read about the Oly UFL-3 strobe. It is a Sea&Sea strobe which has RC integrated. From all what I have read about using RC strobes topside, they work perfect in terms of exposure. 


So after all these words my question: Does anyone have first hand experience with the UFL-3? Does it give perfect TTL-macro-exposures underwater? This would be a perfect "starting point" for my attempts for more creative lightning :)





Any news on the restrictions for 3 Sisters Springs?

07 February 2015 - 02:44 PM

I will be leaving on Tuesday to Crystal River for 10 days. Does anyone know if the discussed limitations like no-go areas inside the spring, no flash photography etc, are in effect? Especially flash photography - if it is generally forbidden inside AND outside the spring, I would leave my strobe, arm, batteries etc. at home - saves some 2kg luggage...

Could not find any up-to-date info on the "Fish and Wildlife" pages.

Kind regards,



p.s.: On a sunny and windy day, I could imagine that in the shallows manatees get a lot "strobe-like flashes" from diffracted sunrays... I took strobe photos some years ago, and not a single manatee ever showed any reaction. Only an idiot would aim the strobes straight into the eyes - why should one? There is way enough ambient light. The strobe is just to light up the belly. But try to tell that a ranger who does not dive... :(   

Bali / Tulamben July 14 with Oly EM5

10 September 2014 - 09:14 AM

Hi folks,


I have uploaded some pics from my trip to the Tulamben area: 




All pictures were taken with an Olympus OMD-EM5 in a Nauticam housing with two Inon Z240 strobes.My lenses: Oly 60mm Macro, 12-50mm kit lens, 7-14mm Panasonic. Subsee +10 adapter.


Most of the pics are macro shots. I visited the Liberty wreck only twice, with decent visibility the first and bad visibility the second time (and way too many divers). Since my wife cannot dive any longer due to a severe eye disease, I do not have a model for WA any more, and without a model I feel WA shots look somewhat boring. So I stayed at the muck sites!


We stayed at the "Villa Markisa" (which is right next to the probably better known Scuba Seraya). If you are looking for a small resort with "style" and comfort in this area  - go there. 




Help needed: What is the thread size of this Ikelite strobe adapter

18 July 2014 - 09:56 AM


The adapter on the attached pic is for using an Ikelite strobe with ULCS and similar strobe arms. I want to use it in a DIY project and need a screw nut for it.

All I know is that the thread is definitively not metric... Could someone please help and provide the specifications (like UNC 1/2")? Thanks!
