Hi there Howeikwok.
I agree with the others. Really superb. I know I can learn a lot from you. I am going to Raja on October 21, and Ammar is going there on a liveaboard around the same time. I don't think I have time to learn macro video before then. Just started shooting with an "SLR" underwater in June. So I am on steep learning curve.
I do, however, want to use a tripod I purchased. I will take the wet wide angle off the housing, and that will leave me with a 28 mm, which underwater would be a 35 mm, which hopefully will focus closely. I would like to ask you some questions a little later about the use of the tripod. I will bring mine and will want to use it for "close ups," or "portraits" as opposed to macro, and then move into macro later.
Thank you for joining the group! Will be back to you soon about the tripod questions.
The 28mm with the Nauticam WWL will focus quite closely. In fact you can shoot a good sized nudibranch with this combination.
