Have photographed them only twice as i live in India. But the first time was a learning process. Ideally its best to take shots while they are coming towards you. Not when they are moving away either side. Panning your camera as they move is also a help.
Hopefully these two images may help get an idea of what i mean. The eyes are in focus, but the background and body of the seal has some blur. To avoid this completely, one has to shoot when the seal is com ing towards you as higher shutter speed is not possible.
Should have clarified. This system is for an NGO working on a marine project. They will keep it, buy it AND we will be using it whenever they call us on some of their projects. We have to advise them on what is best suited within the budget and also buy this for them.
Oh and one more thing Steve, it cannot be a used system. Has to be new!!!
As far as i understand one can use a lubricant made for colored o rings across the board for any other o ring , black or colored. I have used sea and sea lubricant on inon yellow o rings and vice versa. I have not used nauticam on colored o rings but, i think it should work.
Scuba Symphony has o ring lubricants and they are in KL. Maybe you can buy some on line and have it shipped to some place convenient in KL ?
Good luck..BUT i personally think Nauticam lube will do the job without issues.
I carry my nauticam housing with Camera(7D) inside the housing and two strobes (Z240) in a laptop haversack.
