What reviewers say

Reviews praise compact size and attractive JPEG images, but criticise the fixed non-touch screen, restricted 4K video and basic autofocus. Photography Blog recommends paying more for the R50 if possible. Amateur Photographer agrees that it makes many compromises, finding the small viewfinder dim and the controls frustrating despite its low price.
