Methods to determine the appropriate dome port for a wide angle lens in an underwater housing

I have prepared a new piece following the demand here that explains a few methods to determine an appropriate dome port and related extension

There are two versions of this articles

Here on waterpixel in the article section in a slightly reduced form,  to make it more digestable and user friendly. There is a PDF you can download for convenience for offline use.

The full version is on by blog this has more Sony full frame examples but also some point of view which only reflects my views and I did not want that anyone associated those with the team here at waterpixel as they may be controversional to some extent.

The article does not take comments is read only but I am ok to answer questions here or on my blog through the comment functionality

I hope you find it useful.
