What reviewers say
Both reviews praised fast live-view autofocus, stabilisation, battery life and the detailed tilting screen, while criticising the small optical finder and absent video. Photography Blog found images usable through ISO 3200; OpticalLimits was more cautious above ISO 800 and favoured RAW for detail. Both questioned the dust-removal system.
