What Redditors Say
Best praise vs top criticism for Sony a9
Best Praise
+55 ptsâIâve 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.â

Best praise vs top criticism for Sony Alpha a7
Best Praise
+2 ptsâI know a few people who still shoot with the OG A7. Sure the autofocus is dated, but in the right hands will still produce images that can hang.â
r/SonyAlpha
ViewTop Criticism
+1 ptsâI saw this on a very used and beat up A7 that I was trying out (thankfully I never bought it). The lens would slide around quite a bit. I had never seen an A7 before so I thought that it was OK. But actually it's not normal. However this was a known issue due to heavy use on the original A7 which has a mount partially made of plastic. I though they had fixed it on newer bodies. I'm guessing a fall could also damage the mount and make it loose.â
