Re: cameras with good AF performance

face detect AF works good. Might be an option worth trying...

and use Direct manual focus when you find the AF hunting a lot in a special scene..

dont use CAF in such scenes.. its true Samsung doesnt explain that in their manuals, but i also find the CAF making a lot of problems in Lowlight.. i use an NX1 by the way... in low light CAF tends to focus hunt.. sometimes finds focus and then looses it again.. SAF is considerably better in low light.. i also do use Prefocus /locked focus.. i push the AF button on the back and when it has found AF i am set for waiting for the right expression of the subject..of course works best if people are not moving around...like people sitting at a table etc.

also take care how big your focus box is.. bigger box usually works better in lowlight, but you must be aware which contrast it finds.. AF certainly prefers hard contrast and especially vertical lines...
it doesnt like soft contrasts like you find in faces unfortunately.. 
personally i wish for an eye detect AF like Sony A7RII...

for some strange reason it works also better with AutoISO.. maybe the cam finds better contrasts when the scene is exactly as bright as it needs it..
