What Redditors Say
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.”
