Do somebody of you know if there is a Port Chart for the Zen Domes?
If there is, it resides on Hillary Clinton's email server.
No, there is no chart, or at least I have never found one, and they don't list any kind of compatibility on their website. Reef Photo's storefront website give some information but it is not in a single place, or consistent. Generally, you just have to talk to a dealer or to Zen (aka Reef Photo) directly or get input from users. If you ask here on this forum about Zen port compatibility for a specific lens and housing you will likely get a knowledgeable reply pretty quickly. You may or may not get input about actual hands-on experience but usually someone knows what is supposed to fit on what.
