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.”

Best praise vs top criticism for Sony FX30
Best Praise
+24 pts“Fx30 your choice. Same camera but with couple thing more and, active refrigeration. Plug it into some powerbank maybe and you good to go!”
r/SonyAlpha
ViewTop Criticism
+3 pts““…it is important to note that where the FX30 falls short – it’s the “stills mode” when compared to the FX3. Some features and functions are not provided with the new camera. There is no mechanical shutter, continuous still shooting, or uncompressed RAW. Also missing is the image sensor “anti-dust function” and AF illuminator. If you are into photography, you will find that the camera is not compatible with an external flash and NFC communication is not available.””
