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 a7R V
Best Praise
+49 pts“A7RV, absolutely no question about it. If you get in any situation where you might be shooting a burst, the A7CR has an extremely limited buffer. Plus it will handle much better with the larger telephoto lenses.”
r/SonyAlpha
ViewTop Criticism
+22 pts“Hobbyist and limited budget does not equal a7rv and GM lenses lol. If you’re pretty new to photography look towards the APSC bodies (a6400 and a6700) for now and grab some nice zooms if you don’t know what focal length you like most (sigma 18-50 and Sony 70-350 are great). All those combined is still less than the a7rv body, with even enough leftover for a decent prime.”
