I take a practical handheld look at the Panasonic Leica 12mm f/1.4 on the Olympus E-M1 Mark II on a rainy walk.
Images shown at up to full resolution 5184 X 3888 = 20.1 megapixels. Viewing on an iMac 5K recommended as this allows nearly all pixels to be seen (horizontally).
I know this cannot compete with real floods, buy hey—my backyard got 4 inches or rain last night and it’s still coming down. I’ve seen it come down much harder and over a foot of rain in a week before, so it’s not an extreme storm by any means, at least not in the SF bay area.
