+26 pts“I use ISO1600 a lot with my A7RIV, def that ISO is very acceptable with these cameras”
r/SonyAlpha
ViewTop Criticism
+26 pts“Not only they break down, but they are also cursed. Owners mysteriously die exactly one year after the camera breaks down, so stay away from them. This is my last day on earth as my a7r iv broke down exactly 364 days ago. They're already here, at my house. Let this be a warning. I regret the day I touched this damned camera.”
