Thomas,

I think if you more on macro, the 12-50mm macro port will give you more advantage.

I can't say how convenient for you, but I have no problem to rely on the Fn button. Most of the time at 50mm + wet lens and if needed you can switch to 12mm easily and flip the wet lens. 

However, if I really want into macro - such as in Lembeh - I will use my 60mm.

If you have the OMD with 12-50mm and diopter at your hand, just assign Fn button and imagine you are diving in your fav. site and try to shoot any macro object at various sizes you expect you will see at the site.

You will get the felling.

 

Can I ask how you acheived this?

 

Which Fn button are you using as the zoom button and how did you set this up in the menus??

 

Thanks.

You need to assign/set the Fn1 or Fn2 as UW macro/WA toggle through the custom menu-Button/dial-button function.

You may not like the preset setting on this mode. I normally set to M, turn to other mode and return to M.

If you want to stick to one port only, then go with 4" dome port + flip diopter where you can use for 12-50mm, 60mm and 9-18mm.

for 12-50mm, you don't really need zoom gear - just assign Fn to switch to UW macro mode (50mm, and you need diopter) or WA mode (12mm). Set or return to M mode for more control. 

Indeed, the dome port will return/reduce the magnification 25%, but still not very difficult to shoot pigmy sea horse with this arrangement. 

These 3 lens will give you more flexibility with one port.

If you don't know what you will see at site, use 12-50mm, then if you wish you can repeat with the more suitable lens - 60mm or 9-18mm.
