Thank you! I'll be trying it out again this week, then hopefully in the water this weekend.Yes you want macro focus.
The one spec most camera manufacturer's are silent about is the full zoom minimal focus distance.
I need to mostly fully zoom my G16 in order to eliminate vignettes when using a wet lens. So I generally default to always using it at full zoom.
I do not fully understand what type of magic happens when I flip to macro focus (why can't the Canon programmers figure out what is in focus?)
But I have found that the auto focus at full zoom with close subjects works best in macro focus mode. Adding my wet lens (Subsee +10) simply moves the minimum focus distance much closer to the camera.
