What reviewers say
Both reviews praise corrected image quality, quiet fast autofocus and compact size, while stressing dependence on digital distortion correction. Digital Camera World likes the retractable design and travel value, but measures less stabilisation than claimed. OpticalLimits dislikes the extra deployment step and questions pricing against L-series alternatives, while finding strong central sharpness and respectable corrected corners.
