Thanks Bill,

 

I will leave for a non-diving vacation (shame on me...) on Friday, and right now I do not have enough time to post my test results for a comparison. But I will do so when I am back in three weeks.

Giffenk,

 

thanks for your thoughts, but I do have problems with my YS110a AND both of my Z240 V.4 with optical triggering. So all three have a bad optical sync system? Hmmm.

 

The Olympus does not have an option for hard-wiring the strobes, so that is why i tried the external Heinrichs-Weikamp converter. If you do not know it: It is OPTICALLY triggered and sends the signals via cable to the electrical port of the strobes. Unfortunately, the old internal converter (that fits to the cameras hot shoe) does not work with the latest Oly cameras; I confirmed this with the heinrichs-Weikamp office; and they told me they would not produce an updated version.

Bill,

 

as I wrote, on land TTL works 100%: perfect exposure from f/2.8 to f/22. I tried with the small strobe that comes with the camera and with a more powerful FL300R. And with the Heinrichs-Weikamp adapter and a "hard wiring" to the YS110a (sync cable) TTL also works 99% (f/2.8 a little overexposed).

 

I double-checked the fiber cable endings, no dirt or whatsoever on them.

 

Very strange.

In Topic: Advice on next camera to get

12 May 2015 - 01:24 AM

Hi,

the camera itself IMHO just does not matter. The (by far!) most important factor for taking good photos is behind the camera...

Any up-to-date SLR or Mirrorless is "good enough". All the internet rave on dpreview about "camera x" in my eyes is mostly b.s.! Have you ever seen proof, i.e. real photos that have been taken by all those self-named experts? Fortunately, here on wetpixel it is different. Take, for example, Phil Rudin (who is mostly active in the mirrorless sub-forum): He is talking a lot about cameras, lenses, ports, technical specs and so on. BUT - he does not just talk, he has been using himself the gear he is talking about. And he supplies photos he took with this special gear.

Just a few things you should think about:

- If size/weight does matter, micro43 could be an option.

- First thing I would worry about is choice and availability of housings. So you now have the ultimate super-duper camera, only to find out that there is only one housing on the market, and you cannot operate all those tiny buttons on the back with your clumsy fingers and/or when wearing gloves, or you find that the housing is too big for your small hands. You need to take a housing physically into your hands to find out if it is okay for you.

- Next thing is choice and availability of lenses suitable for u/w photography (for example, you may have a limited choice with Sony) and their corresponding port systems. There are many threads about port/lens combinations here, but I think first choice should be the recommended combination from the housing manufacturer, they have tested it (or they should have...). Of course, if you already have some "good" lenses that you use u/w and want to keep them instead of selling them on ebay, then your camera/housing choice is limited.


Regards,
Jock

... A talented photographer like Amanda can find a way to make things work to produce publishable images.

 

Phil, you are so right! Unless you buy some really cheap stuff you cannot go completely wrong with todays u/w-photo equipment. Sometimes I feel that people`s photos would benefit a lot more if the time spent on studying technical specs would be spent on studying composition, creative lightning and things like that. A dull picture with perfect, spot-on sharpness from corner to corner is still a dull picture... 

 

Rugani, what are you going to do with your pictures? Publish them in a coffeetable book or National Geographic? Print them regularly in a very large format? Or -to be honest- mostly look at them on your PC or Mac? Think about it...

 

Ah, and go for the 7-14mm lens. You will love it, it is just great.
