>>4276995No crop, just insufficient SS and some funny business during compression, I imagine, didn't even notice that very weird, seemingly almost straight line of distortion, best guess is that having the lens that close to the ground may have gotten water on the lens/between the subject and lens, or that the plants end point made a weird pattern in the out of focus area where the blades of grass overlap the feather, it's also present in the raw. I treat birds mostly as practice but I don't really care to knock the genre
