reviews

    • “exceptionally sharp, especially when stopped down slightly. When used wide open at ƒ/1.4, the vast majority of the frame is incredibly sharp, tapering to very light corner softness in the extreme edges. Stopped down to ƒ/2, this corner softness is dramatically reduced, and disappears completely at ƒ/2.8 where the lens is tack-sharp across the frame. This sharpness continues all the way to ƒ/11”
    • some CA wide open across the frame in high contrast situations but improves as stopped down
    • “build quality is excellent”
    • “very fast to focus on the new DMC-G3 camera and almost virtually silent too thus suited to videos”
    • “hood does almost doubles the length of the lens”
    • “an excellent performer…you can safely use it wide open for maximum bokeh and still achieve sharp results in the centre of the frame”
    • “optimum performance stop down to f/4, where even the edges of the frame look sharp”
    • “CA is almost completely absent, while distortions are automatically corrected on both Olympus and Panasonic bodies”
    • “creamy bokeh and snappy performance”
    • “highly recommended”
  • Kirk Tuck's view - “superb” but on an Olympus body the aperture becomes very noisy in bright light as it continuously opens and closes.
