Samsung NX30 review – Autofocus
The Samsung NX30 boasts an advanced hybrid autofocus system that uses the 105 phase-detection and 247 contrast-detection points. This is the same autofocus system first used in the NX300 and later in the Galaxy NX. However, Samsung says it has improved the autofocus speed by 35% when compared to the NX300. When used, it certainly did appear faster, most noticeably in low-light situations. In very low light the focus would lock on to low-contrast subject areas in around 1/2sec with a good degree of accuracy, although not faultlessly. In optimum lighting conditions the focus is very snappy and accurate achieving focus without much delay.
Thanks to the touchscreen, manually selecting a focus point using spot AF is very easy and achieves great results. Also, for those with a preference for manually focusing, the NX30 has focus peaking and controllable MF-assist that enlarges an area x5 when the focus ring is moved. I found this particularly useful for shooting portraits with a shallow depth of field in order to get the focus precisely on the eyes.
