Reception

Photozone reviewed the lens favourably, stating, "in terms of resolution and contrast the lens is able to produce very good results straight from the max. aperture setting" and "mechanical quality of the lens is absolutely exceptional thanks to high quality materials and seals against dust and moisture". Of the ultrasonic autofocus motor, they wrote that it "works like a breeze - it's both fast and almost silent." Overall, they concluded that the lens is "highly desirable lens for sports and wildlife photographers."[2]

ColorFoto wrote the lens had outstanding sharpness over the entire frame, even wide open,[3] and PopPhoto.com said that "images shot in the field were satisfyingly contrasty and sharp."[4]
