In Topic: Are people leaving micro four thirds?

28 April 2016 - 03:54 PM

I'm in the same situation as Tropoboro. What I think has changed is that the blitz of excitement from the release of first the EM-5 and then the EM-1 has died down, so there is less enthusiastic chatter but still a lot of happy users. I'm taking my EM-5 down to Egypt in May and unless the EM-1 Mk II has some major features of interest it may serve me for another 1 or 2 years. Both travel/size plus lens selection and cost keep the m43 system very attractive.

In Topic: Using Macro extension tubes with Olympus 60MM and nauticam housing

The extension tubes give you extra magnification by allowing you to get closer. But that will further reduce the precious space between the lens and subject. Loosing another 2 cm due to a port that is longer than necessary might be too much. If you can get your hands on the extension tubes you may want to experiment what the minimum focus distance ends up being before buying the tubes and port extender. Finding out the maximum focus distance could be of interest too as you'll be stuck with that for the entire dive.

In Topic: Milne Bay Rhinopia/Scorpionfish?

23 March 2016 - 08:08 PM

I'm quite convinced that your image is the same species as the Alamy photo but I just don't know how reliable their ID is and would feel better if there was a similar image form a "trusted source". That said it is the only reasonable match in the very complete Fishes of the East Indies and together with Fishbase referencing the blue dots I think it is a good match.

In Topic: Milne Bay Rhinopia/Scorpionfish?

23 March 2016 - 03:54 PM

In Reef Fishes of the East Indies the only scorpionfish with bright white patches and the prominent tentacles above the eye is the raggy scorpionfish (Scorpaenopsis venosa). The description indicates that "tentacle above eye often present and up to twice orbit diameter in length". That suggests the tentacles can be absent and many imaged labeled as S. venosa indeed lack the tentacles.  Fishbase describes the appearance as "Adults are best recognized by the tiny light-blue ocelli scattered over the body, and dark triangle below the eye. Small juveniles have three distinctive white spots along the back". Finally, I think there is a very good match with the image below, which was also IDed as S. venosa.

Too bad you didn't get a better image because this colour form seems to be rare, or just rarely photographed.

In Topic: Finally created an online portfolio

Very nice shots from Fiji & Wakatobi. Liked the Red Sea images as well. For some reason New Caledonia and the Great Barrier reef images look quite different.

 

Thanks for sharing.
