What reviewers say
Both praise the compact handling, attractive images and effective stabilisation, while finding continuous autofocus less suited to erratic movement. Amateur Photographer likes the twin dials but finds touchscreen control incomplete and the selfie screen awkward on a tripod. Photography Blog finds the improvements useful for new buyers but too modest to justify upgrading from the Mark III.
