A couple of waterfowl images taken with the Olympus E-M1 Mark2, 300mmf4 plus 1.4x.
Northern Shoveler ISO400 1/1600sec, f5.6
Common Merganser ISO800 1/1250sec, f5.6
Pouring rain as I left the house so grabbed the Olympus. Harder rain at the trailhead. Torrential rain when I made it to the falls. No hesitation taking the Oly out of the non-waterproof backpack.
