In Topic: Dry Suits - How to?

21 February 2015 - 01:39 AM

There are many ways how to control buoyancy in dry suit. It depends from the type of dry suit, volume and type of thermal protection layer. I saw that discussions many times. In my opinion there is no sense to discuss this via internet. How to swim in dry suit You can learn only in the water, with experienced colleague or instructor. And the end it is easy, but if You learn to make mistakes at the beginning, then it can go wrong. The is one main thing which can happen wrong: You will fly very fast to the surface with Your legs on the top and head still underwater, without possibility to roll and release the air.

I have 30mm macro lens and I would say it is not the best one for macro, because very short focusing distance. For corals or stones it is ok, but for living creatures not so nice,


My colleagues get nice results with 50mm lens and additional wet macro lenses. The same 1:1 factor is possible to get at longer distance.


I just saw that the extension tubes will increase the focusing distance and some Nex users are satisfied with this solution.


so I am just interested if this will work underwater, and maybe the combination of extension tubes and wet lenses will offer the magnification like 2:1


I know that Canon 100mm f2,8L macro lens with metabones can be better solution, but I am trying to work with what I have, without increasing the price of my setup by factor 2x  :)
