Rain with OM 20mm f/1.4 PRO Lens

I’m trying out the new OM 20mm f/1.4 PRO Lens on my E-M5 III camera.  I have mixed feelings about it, probably due to the cost.  I wish that I had this lens when I toured Ireland when we had frequent rains, but I did alright then with my 20mm pancake lens in between rains and kept my camera in my raincoat pocket when it rained.
