Sony a6600 vs Sony a7R IV

“That 200-600 is a solid lens. I use it too. But you're right to struggle, and it's not you. You're fighting the A6600's AF. It's just not as fast as the newer bodies for BIF. That's the honest reality. Two things to try: 1. That lens *needs* sunlight. At f/6.3, the AF hunts like crazy on dark days. 2. Don't use "Wide" focus. It's just guessing. Try **Tracking: Expand Spot**. Lock onto the bird *before* it moves. It gives the camera a fighting chance. And don't believe the hype you see online. My keeper rate is tiny. I'll shoot 300+ photos to get maybe 30 "keepers." That's just the grind.”

“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.”
