Panasonic 14-140ii or Olympus 14-150ii on GX8? (or other options?)

All

Thanks for trying to help.  I think I will just buy an Olympus 14-150ii and compare with the Panny 14-140 in practice, and see whether the Oly IQ matches that of the Panny with IS.  If it does, I will probably stay with the Oly for the comfort of water resistance (even though it is only slightly better in that respect than a 'non water resistant' lens according to one report)  The other will go on ebay, any $ loss will be worth it to find out to my satisfaction

I can also see whether I think the IQ of whichever I decide to keep is good enough for a general purpose tele lens, or whether I am going to have to get the 35-100 f2.8 as well.

Of course I am assuming that with GX8 and a suitable lens I will get better results for on the water shots than I do with Nikon V2 and 30-110.  Not necessarily a given as a Sony a6000 definitely fell short and has now gone together with all its lenses.  The focusing and IS of the little Nikon is just spectacular for daylight action.

So far as shooting from a rubber duck (RIB) is concerned, I do it almost every month as I go to sailing events.  I have not lost a camera yet (I hope I am not tempting fate by mentioning it)  I have struggled with various water shields and covers, but find that they are all too difficult, when one hand is holding the camera and the other (mostly) holding me into the boat.

I am pretty careful to keep the camera in a dry bag most of the time when I am not actually taking a shot. and when I am, shield the camera from spray as best I can.

The trouble is that with the boat I am on bouncing up and down, and the sailing boats also moving, getting sharp shots needs a fast shutter speed and good luck.

My next event starts on Thursday, but I won't have the Oly by then.  I'll post some shots.

Cheers
