The scene was gloomy as well as foggy, and the GM1 picked up some purple fringing that I left for another time. This was cropped from 4600 wide to 3900 wide and resized. f9.0, 1/400 handheld, ISO 200. The people were about 150 yards distant (64 mm effective focal length) on a 400 yard length pier. The quality isn't great, but given the tiny camera and spontaneous handheld take in bad lighting, I thought it did pretty well.
