Here's a shot that's been puzzling me. I took it with a Rokkor 40/2 on a CL over Thanksgiving in Newburyport, MA on Kodak HD 400. The mid-afternoon sun was well to my left, and I was using a lens hood. I'd suspect a light leak or a shutter problem but it's the only shot with the problem and the camera was thoroughly overhauled last year. (The shot is in mid-roll, I didn't change lenses during the roll, and I try to avoid pointing the camera at the sun. I had a half-case on the camera as well.)
As I scanned this image just now, I looked closely at the film strip and saw that the "flare" extends into the area beyond the frame and crosses the sprocket holes on top. I wonder: drugstore-processing error or something else?
