What reviewers say

Both reviews praised detailed images, the lens and compact handling. Digital Camera World valued the portability and autofocus, finding absent stabilisation manageable. Tom’s Guide found low-light autofocus less reliable and value poor. Both missed a tilting screen; Tom’s Guide’s short battery result used a third-party battery, limiting its relevance to Sony’s claim.
