Nope, no streaking, but I do get flares, so I do try and find an optimal place to stand. Anyway, you should really test it, just rent the camera, if possible, as everyone has different needs and use cases. My ONLY problem with the GH6 is battery life, 4k 60p 4:2:2 runs for around 1:15 hours, when the battery starts flashing, and I still havent found a reliable way to power the camera on the go without using the usb-c port.
