A review by photozone noted the lens' high lateral chromatic aberration and low edge sharpness, while suggesting that distortion was typical the genre and vignetting relatively modest, while autofocus was "good" and optical stabilisation competitive.^[2] The latter was evaluated by DPReview as "at least 3 stops benefit" (sic), adding that while the lens was resistant to flare, changing aperture also shifted focus, making macro shooting difficult.^[3]
