What Redditors Say
Best praise vs top criticism for Sony a6400
Best Praise
+82 pts“I recommend learning the exposure triangle, basic composition, and most importantly what many people dont mention is post editing. The 6400 is a very capable camera of taking stunning pictures. Also are you only using the kit lens? Id also graba 50mm 1.8 for portraits and to get some nice backround seperation.”

ViewTop Criticism
+24 pts“Pretty sure the A6400 has the same menu system and no IBIS, so it isn’t going to address the issues you’re having with the A6000.”

What Redditors Say
Best praise vs top criticism for Sony a7 IV
Best Praise
+140 pts“I have had A6400 setup like that on a tripod in a studio for like 2 years. Where the collar mount was holding the lens and the camera was dangling for almost 2 years while I ran a studio. Didn't have any issues. Then again, I had setup where the A7IV was holding up 24-70GM for 2 years as well during that same time period as that was the main camera that I used. Didn't see any issues.”
r/SonyAlpha
ViewTop Criticism
+29 pts“This- I am most excited about the cooling. Gerald undone tested it an could get 6 hours on 4k60 in 22 degrees C. This is huge because most camera systems start overheating after even 30 minutes in 4k25. I couldn’t use the A7IV because of this in ceremonies and longer events. Sony are claiming that it will do 4K25 for 60 minutes in 40degrees Celsius which is incredible if true for something with no fan”
