Gary Wolstenholme reviews the Fujifilm Fujinon XF 55-200mm f/3.5-4.8 R LM OIS lens.
Excellent performance at 55mm; Low distortion; Good build quality; Very effective optical stabilisation; Fast linear focusing motor
Drop off in sharpness as lens is zoomed towards telephoto; May be a little pricey when compared to equivalent lenses for other systems
