Sony a6600 vs Sony FX3

“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.”

“People like me that are hybrid shooters and clients require both video and photography in the same shoots. An EVF is essential for photography so the fx3 is useless to me. We already must each carry at least two cameras for different lens options/backups. Imagine if we had to do the same for video, we would need 4 cameras per person. By the a7s existing, that cuts it down to 2. If the fx3 had an EVF, then maybe I would agree with you, but until that happens, I hope the a7s line never goes away and instead they make an a7siv with 24mp so that the photos have more resolution and it can do native 6k.”
