In Topic: INON Dome Port for OLY 8mm Fisheye?

19 January 2016 - 09:52 AM

The Oly  8mm 1.8 and the Pana 8mm 3.5  fish-eye lenses  will profit most from  a 100mm  mini dome. But for the longer Oly fish eye lense you will  need an extension. I found the Zen 25 mm extension very useful.  This set up  allows me  to use both fish eye  lenses,  the long Oly (with extension) and the shorther  Pana  (without extension)  on the same  PEN housing. I suppose that both the Zen 100mm dome and  the Precision100 mm  dome  will work  fine on these combinations.

I forgot the name of the boat...so dont take it (-;   Three  things  went wrong with our trip 1) most of the sharks went to other boats  in the line of boats anchored along the island 2)  Our mexican  guide  spent most of his time playing  games on  his computer 3) the chumming device (a tube under  the boat)  constantly spread chum  through the cage.  

Yes,  I took the Tokina which  is OK because you can zoom between 10 and 17 mm.  A  small camera with a wide-angle lense  and filter,  no strobes would also be fine. And a thick suit!

I think Solmar V has a good reputation.  The location as such is perfect,   Have fun!

From 'fisheye' to fish eye.

The eyes of most fish species are not so much different  from  the human eye. Their retina  contains rods and cones,  thus the  ability to perceive visual details, colours as well as changes in brightness. Unlike humans, fish normally adjust focus by moving their lens closer to or further from the  retina. Different fish species have developed special  visual abilities to survive in their specific habitats. Fish that live at greater depths have adapted to darkness  by  developing  a  greater sensitivity to light and changes in brightness. Coral fishes have developed special colour, stripe and movement patterns as camouflage to trick other species (who lack the ability to detect, or are fooled by their visual tricks).  

So fishes may not differ  so much in visual abilities from the UW Photographer There is even an example of a tiger shark in the Bahamas that stole a camera and appeared to have taken several  pictures of her environment after recovery of the camera  (-;
