Best praise vs top criticism for Sony a9
Best Praise
+55 pts“I’ve been looking religiously on marketplace and eBay for a A9 for the past 2 weeks straight, sun up to sun down. I found this A9 with less than 100 s count for $1200.. not a single scratch on it. I was waiting for my a7ii to sell before I bought a new body but I caved and went to meet up with seller. Coming from an a7ii it feels like cheating with this AF and FPS, lol.”

+52 pts“Here’s your second bird 🖕 I’m kidding, lovely picture, I have a 6600 as well, always happy to see someone with one post.”

+17 pts“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.”
