What reviewers say

Both reviews praised image detail, comfortable handling and long battery life, while finding the fixed screen and limited live view restrictive. PhotographyBlog considered the feature mix uninspiring and preferred neighbouring Alpha models. Amateur Photographer found it a worthwhile affordable upgrade despite awkward controls and weaker low-light autofocus; its conservative high-ISO assessment differed from PhotographyBlog's enthusiasm through ISO 3200.
