Hi mates,

For 13 years i use the combo 8-15 with 100m dome (Aquatica) and now 140mm on Nauticam (complete switch to Nauticam with Canon R7 as Aquatica support in Europe is !$#@$).

However, i wanna more flex during science missions - mean to have wide and macro at the same time.

Thus am thinking to move to WWL II and CMC on the handy 18-45 Canon lens.

Has anybody experience on such switch?

I moved from SLR and assorted lenses to m4/3 with a kit zoom and wet lenses a few years back. It works well for a journalist approach to a dive site. One site, get the wide angle to set the scene, fish in the middle, then macro all in one dive, then swap back again when the whale shark shows up! Then on to the next site.

Wide angle is comparable to before the move. I find the main difference is on macro, where the CMC has to be close to the subject. A dedicated macro lens could achieve similar magnification from a little further away. In some situations that is a plus, and in some situations its a limitation. But its not a like-for-like comparison because I have never owned a dedicated macro lens for m4/3.

If choosing again today my ideal would be a primary lens 60 or 105 macro (full frame equivalent) and a wet lens to convert that to wide angle. I would loose the ability to zoom for convenience at the extremes. But the balance of my diving has changed. I used to do a lot more wreck diving. Now I do more macro diving. Without travelling with a full shed of camera kit most of us need to compromise somewhere.
