Currently I'm looking for used A7 or A7r but dunno which is the good buy , either go for new A7ii.

Do you guys have any opinions or experience on Sony A7 performance, image quality with ISO else.

Thank you so much 😊

i used sony a7 before, but you compare with a7MII the autofocus is faster 20% not just video and also photo too on af iso is about same with a7 plus a7 dont have 5 axis but a7MII got this i can say if you are video lover then is this is good for video. one a7r autofous is slower but good thing is the pic megapixel is very huge for photographer for the video still ok

Thanks a lot for that 5 axis really help up when taken micro with video.

but then if you on tight bajet also can use sony a7 is really quite good camera just got a few problem i find out is the autofocus slow compare to a7mii second is the battery juice quite fast haha compare to dslr due to using Electronic view finder EVF power haha and also the mount of the camera of sony a7 it will lossen one after a few years you need to change metal e-mount ring, there is no 5 axis, hand held if you ask me i prefer sony a7 more nice than sony a7mii of course got pro and con la anyway sony a7 is really a beginning FF E-mount camera anyway bec of gst i force to upgrade to a7mii haha is really feel the different you can feel the iso can pump to 6400 and still good that time im using 24-70 f4 with sony a7 anyway have fun

Not sure where you got that from, but ALL A7 series comes standard with metal mounts.

yes is a metal but the original one will loosen one after 2-3 yrs for sony a7 mount and also you will find it out got a gap between lens and also camera there

Are you able to quote a source where you read that from? Just curious to know.

im using the sony a7 before i facing some problem especially some lens was not able to detect is show F_ _ on aperture im using sony a7 for 3 yrs already so far lens also no change before or take out it still loosen on sony a7 e-mount

What is the lens has it issue?

no no is not the e-mounts lens problem is the sony a7 mount body there with the lens it will have a small gap one you will notice it after used for 3 yrs on sony a7 but then sony a7mii this problem solve already so no issue already that why for sony a7 they need to replace this https://www.amazon.com/Fotodiox-Mount-Repla...s/dp/B00OI8WK1M after replace it then no problem already

Just maybe in the first batch had an issue or defected.

Ok, found what you meant by that...
