You can't always. Try sending a Samyang for that, for example.

 

Also, if you want people to behave as if you're not dog poo, seriously dial down your tone. You have probably insulted everyone on this forum here and there and believe it or not, probably nobody really likes you. I'm taking my sweet time to beat some sense into that thick skull of yours but only thing I get is shit coming out of your fingers, which would originally come out from your mouth but this is the internet.

 

So, unlike you, I'll say this only once: I'm done with you. Go ahead, post another message and have the last word. Nobody cares you do since nobody really takes you for anything serious. I just hope you don't realize what a useless asshat you have been someday and commit suicide all alone in your apartment and frame me for it.

Samyang lenses are not AF. So, they can't front/back focus with AF.

What does the focus screen have to do with front/back focus? Totally nothing at all.

 

That you want to continue to flame just says a lot about you.
