Best praise vs top criticism for Sony Alpha a7
Best Praise
+2 pts“I 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.”
r/SonyAlpha
ViewTop Criticism
+1 pts“I 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.”
