In Topic: Great hammerheads of Bimini

what camera and lens combination did you use? what were generally the camera settings?

Some of the pictures when looking greater than just thumbnails are unsharp. I am asking this not as a critique but will go soon to the bahamas for the closup encounters with the Longimanus (Cat island). thanks

In Topic: Float arms.

29 October 2014 - 12:33 AM

I am using Naticams 60x200mm fibre float arms with positive buoyancy of 235g each. I can recommend these. They also have those 250mm lengths with a lift of 350 grams.









In Topic: Am I going soft: Nikkor 16-35mm

14 September 2014 - 11:15 PM

I have a similar setup with a D4s, Subal 90mm extension ring, a +2 diopter but a 9" dome port (DP-230). As you can see in this image the left corner side is still not fully sharp, but acceptable.

shot with 16-35mm @16mm, f9, 1/80sec, ISO 800. I have read somewhere, that this lens is sharper at around 20mm and not so sharp at 16mm.

In Topic: Port for Nikon 16-35 on a Subal Housing

05 September 2014 - 12:02 AM

I have the same configuration (although Subal DP-FE9) and using the 90mm focus extension ring and a +2 diopter. you could eventually stack your 50mm and the 33mm, although sub-optimal I think.

In Topic: fogging dome port and lens while video recording

02 September 2014 - 11:55 PM

thanks for all the replies. I am now convinced that this was causing the fogging. Interestingly it never happened before with same procedures when shooting stills only. but with video operation and thus warming up the air inside the aluminum housing it obviously triggered the fogging. As a matter of fact on the last dive in Dirty rock were 2 whale sharks turning on and on for about 30 minutes and my lens was completely fogged....I almost bite the mouthpiece of the regulator.....Lesson learned!



I was there the last 2 weeks (mid August till end of August this year). we did not really notice a real El Nino effect. Water temperature was about 26 degrees of Celcius with some thermoclines of down to 20-21 degrees. Schools of hammers were there (more than in my last visit 2 years ago), sometimes with more than probably 100-200 animals, but I had the impressions that they were not so active on the cleaning stations anymore (and this situation is usually the only occasion of close encounters).


Seen also whale sharks (about 5 within the 2 weeks), galapagos sharks (many), silkies and silver tips, blacktips and off course white tips all over. Also 2-3 times tiger sharks (but not that close). And they were not anymore in Manuelita   channel. Top diving places for the hammers were Dirty Rock and partly Alcyone (in fact in some dives Alcyone was completely dead). 


Visibility underwater was rather low, shot with up to 1200 ISO in 35 meter depths (Dirty Rock, Alcyone). topside rainy every day. Did practice more on the "higher ISO - lower flash power - faster frames" shooting style and like it very much...


But still did enjoy it very much despite the excessive traveling going there. I think Cocos is still one of the top 10 places in the world.


A few images (ok, the tiger shot is rather low quality due to heavy cropping since far distance shot at low visibility and almost no flash lighting):
