photo issue question ... for @sonyalpha or any one out there who has experienced this. these what i call "60 hertz cycle lines" appear in some of my images under certain lighting when i shoot over 1/40th in this case i was using the #a7rii and probably 1/60th . i don't know CFL lights cycle on and off 60 times a second so capturing a point where the light is off was possible though we can't see it with our own eyes. it doesn't happen all the time and i am beginning to think it has something to do with a setting "silent mode" or "electronic shutter" being on or off. i know i could experiment and find out i guess but i never get around to it. google was no help. any ever experience this know how to resolve it besides shooting 1/40th or below. #sonyalpha #a7 #60cycle #sony
