Have any of you gone from using an EM5iii to an OM-1?  What appeals to me is the longer lasting battery and perhaps a brighter screen.  I've read articles that the EM5iii / OM-5 focuses more accurately in low light than the OM-1.  Is the auto-tracking on the OM-1 a game changer?  It seems that using a fisheye lens would be less critical.  Yes, I'm sure I'm over-analysing all of this.  I'll be on a liveaboard for my first trip to Indonesia.  Otherwise, I'm diving in the cold waters of the Pacific Northwest.

I'm using the OM-1 previously the EM-1 MkII and the EM-5 Mkii.  The auto focus is fast and snappy on the OM-1 in most circumstances, but can slow down a little with high magnification.  It's a step up over the EM-1 MkII in everything bar tracking.   UW using the  60mm macro it is pretty good with little hunting.  I haven't used the subject recognition UW and the tracking works sometimes, but I tend not to use it much UW.  The subject tracking/recognition  is great above water.  With a fisheye it's seamless and as you say no need for tracking in any shots I've taken.
