Best praise vs top criticism for Sony a9
Best Praise
+26 pts“I use my good ol A7M3 as a wildlife camera with an Tamron 150-500. works great! Sure an A1 or A9 is „better“ but the price tag? I’m happy with its capabilities. https://preview.redd.it/nks5xr7m34xe1.jpeg?width=2845&format=pjpg&auto=webp&s=297fb38f2984a0211a347b3ad7aa0033c685b23b”

+242 pts“That’s great. With the price drop of the A7 IV the A7 III on the used market will also go down, which means I can finally afford the A7 II.”
