   *Bad spatial filtering isn’t new to Sony’s Alpha cameras. Even with the older firmware, all recent Sony alpha mirrorless cameras including the a6000, a6300, a6500, a7S, a7R, a7, a7II, a7sii, a7rii exhibit the “Star Eater” issue when using the Bulb exposure mode - in these cameras, ​ use timed exposures not BULB!   *Bad spatial filtering isn’t new to Sony’s Alpha cameras.
