What Redditors Say
Best praise vs top criticism for Sony FX3
Best Praise
+50 pts“Right so about 99% of the work I do is video based. I have a Nikon Z7ii that I’ve been using but the video capabilities just aren’t where I need them to be so I went all in with the FX3. The G master lenses were the other thing that pulled me in”
r/SonyAlpha
ViewTop Criticism
+2 pts“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.”

+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.”
